Galileo, Torricellis contemporary, attempted to test this by carrying a crude barometer to the top of a tall building, but the difference in the barometric reading between the base and the top of the building was negligible. There were 15, then 8, then 4, then 2; then, after the fifth toss, this one student remained. Deduce what? said he, petulantly. c. undesirable Null hypothesis : this is known as the default hypothesis.It states that e. modeling, c. an interaction of situations and personal beliefs, The general aggression model proposes that when aggression occurs, it will be That explanation has a nearly nil prior probability, since it does not make any sense; there is no uncontroversial example of this sort of thing actually happening, and we havent the slightest notion of the causal mechanisms that would be involved. Make observations. Which of the following shows the correct order for a scientific explanation? C. An increase in family income leads to an increase in the percentage of income spent on housing. WebTranscribed image text: www.bbt.com Our Time.com Cesearch Foundations, Process, and Ethics Savod Which of the following is an explanatory hypothesis? For example, our hypothesis in this case could be that the toast didn't toast because the electrical outlet is broken. The lad said that Suzy and the hired man were up in the hayloftthat Suzy had her dress up and the hired man had lowered his trousers. They were all concerned with describing and understanding the inner experience. d. They see it as part of their role. What is the name given to this step of the scientific method? A body of knowledge based on observation, description, experimentation, and explanation of natural phenomena. Another way to put this is to ask whether there is a satisfactory conceptual framework for the general explanationand whether it is more satisfactory than the alternatives. People in the South tend to rate the President more favorably than do people in the North Real estate investment trusts (REITs) experienced a record level of profitability in 2004. Punishing student pilots when they perform poorly is followed by improved performance more often than rewarding them when they perform well. The researchers also monitored a drought that killed off 85 percent of the finches on an island one year. When we compare frequencies we see that the prior probability of each portion of the plumber explanation is quite low; and the conjunction of all portions (recall Chapter 10this requires that the probabilities of all the parts be multiplied) is far, far lower. A set of analytical and mathematical tools designed to further the understanding of numerical data. Suppose I say to you, If he is from Chicago, then he is from Illinoisand he is indeed from Illinois, so he must be from Chicago. You cant be absolutely sure without some wider context, but it normally wouldnt make sense for me to explain someones residency in Illinois by pointing to his residence in Chicago. a person's unconscious. But there is a viable alternative explanation for this outcomenamely, Escaping from a shipwreck is largely a matter of luck, shipwrecks having little regard for passengers religious beliefs. Suppose the prior probability that the butler did it was .10, likewise for the chambermaid. Is there no other explanation of the outcome that already exists? This can be a useful standard, but remember that surprise is a psychological conditionthus, strictly speaking, it is an indicator of low subjective, rather than epistemic, probability. Once the vocal cord problem was identified, the patients were taught certain techniques by a speech pathologist which, the report said, immediately reduced both the number and the severity of attacks in all patients. For her part, Delynn Carter said she knows what triggered her attacks. It is doubtful that more than 1 in 30 is able to win five years in a row on the basis of skillthat is, the probability of succeeding for five years by skill is probably no better than the probability of doing it by chance. A theory has been extensively tested and is generally accepted among a set of scholars; a hypothesis is a speculative guess that has yet to be tested. Neither the researchers nor the study's participants know who is receiving the drug and who is receiving the placebo. Rabinoff.). Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. a. situational causes Butterfingers, of course. or she may have been secretly using a two-headed coin. Is the foundation of all scientific experiments. This terminology is acceptable but can be misleading, since many theories are quite factual and many facts are highly theoretical.[1]. Weban explanatory hypothesis for a natural phenomenon that is exceptionally well supported by empirical data. Average people will harm others if told to do so by an authority figure. Describes knowledge that is based on experience and observations that are rational, testable, and repeatable. You must have observed the way in which he held his head and swung his cane. her own conscious experience. Examine the list of all known species of birds and determine if any cannot fly. In other words, it means that you cannot use all of the relevant available evidence in making this particular judgmentyou must exclude the assumption that the explanation is true, and you must exclude observations that might have already been made in the attempt to verify premise 2. More precisely, the condition is that the prior probability of the observable outcome must be sufficiently low. My wife calls mePapa Bear. e. They were born with an aggressive urge, e. They were born with an aggressive urge, Research on game reasoning (also called bracketed morality) has shown that b. In scientific thinking, which of the following are not subject to revision? The first part focuses on the importance of the improbability of the outcome. I offer the observable outcome that I walk around on the ground while I wear the shoes. One morning she wakes up after a late night reading and finds her vision is somewhat blurred; she immediately diagnoses optic neuritis. Note: See Section 6. But in an Oregon State University study that was replicated several times, wild frog eggs were placed in 72 cages, some with filters that let all sunlight inside except UV radiation. The notes said: If you find this note before May 1, call David Bell at the, Delynn Carter learned that the dramatic episodes of wheezing, which incapacitated her almost daily for the last eight years, were due not to asthma but to a vocal cord dysfunction that mimicked the symptoms of asthma and can be treated by speech therapy. c. with the intent to harm psychologically. The second premise states that the observable outcome has happenedthat it really has been observed. b. athletes view aggressive acts as more appropriate in society than in the sport environment So the scientists are wrong when they reject the paranormal, ancient astronauts, and homeopathic medicine! WebA hypothesis is a potential answer to the question, one that can somehow be tested. Want to create or adapt books like this? The second premise states that the observable outcome is known to have happenedthat it has been observed. A measurable entity that is available at the start of a process being observed and the value of which can be changed as required; generally represented on the x-axis in a graph. . Newtons theories, for example, while applied here to Halleys comet, actually cover the motion of all objects at all times. I have a pretty young wife (my second) whom Ive always trusted until last Friday night when I came home, put on my bathrobe and found a well-used pipe in the pocket! The second part of the total evidence condition requires that you exercise the same imaginative powers as the arguer; for you must imagine which explanations would be the most credible alternatives to the one argued for. Develop an action plan. e. all of the above. c. psychologically harming another individual Abbys explanation is that the wife is having an affair; the observable outcome is that the pipe unexpectedly appears and then mysteriously disappears. Real estate investment trusts (REITs) experienced a record level of profitability in 2004 Soles Its a favorite of macabre schoolchildren. When you cannot think of another explanation, it can be tempting to accept an explanatory argument even when the prior probability of the explanation is exceedingly low. The planet is too dim to be seen, but the scientists said they are convinced it is there because the pulsar emits radio signals that vary in a way that can best be explained by the gravitational tug of a nearby planetthe waves are a bit early for three months, then for three months arrive a bit late. But you can still ask whether such explanations make sense, and whether they make more sense than the alternative explanations. And whatever happened to Satcom III, the telecommunications satellite that some say almost crippled the satellite insurance industry? If your hypothesis is "Echinacea reduces the duration and severity of the symptoms of the common cold," what is your null hypothesis? Suppose I have heard that vitamin C prevents colds; I dont know whether to believe it but decide its worth looking into. Singular explanationan explanation that is designed to apply only to a single thing or event. The requirement that it be possible to specify some observable outcome of an explanation that could prove it to be false. A hypothesis is a tentative explanation . We are the only two people in this apartment. A 17-pound meteorite of unknown origin was found in Antarctica. He said he came home to discover a well-used pipe in the pocket of his bathrobe. Just like the coin-toss and mutual fund cases, coincidence does make sense and is at least as likely here as the paranormal. The correct form for an explanatory argument, assuming that P is the explanation and Q is the observable outcome, is this: The first premise, often implicit, states that the explanation enables you to predict the observable outcomethat it really is an outcome. For a solution to be termed a scientific hypothesis, it has to be an idea that can be supported or refuted through carefully crafted experimentation or observation. Taken from the DEAR ABBY column by Abigail Van Buren. [Hint: First find P2P^2P2. An explanatory hypothesis is a type of hypothesis which is used to test the cause and effect relationship between two or more than two variables. Pa! exclaimed the youngster, they are getting ready to pee on the hay! Well, son, replied the father, youve got the facts all right, but have reached the wrong conclusion. Lincolns client, we are told, was acquitted. With total restriction of fluids, death follows in 24 hours. It included an account of the physical laws that govern the interactions of the planets, stars, and other heavenly bodies. But it turned out that concrete was available only when mild weather had been predicted. Treatment: in a research study, any condition applied to subjects - those in the treatment group - that is not applied to subjects in a control group. For a solution to be termed a scientific hypothesis, it has to be an idea that can be supported or refuted through carefully crafted experimentation or observation. If the prior probability of the explanation is extremely low and coincidence has not been ruled out as an alternative explanation, judge the logic of the argument to be weak. Cells carry out the functions necessary for life. Sit down before fact as a little child, be prepared to give up every preconceived notion, follow humbly wherever and to whatever abysses nature leads or you shall learn nothing. Research testing the catharsis notion of spectator aggression has shown that Ask whether the outcome is too vague. One good way to check for an improbable outcome is to ask this: Is this outcome so vague that it might well be true anyway? Im illegitimate.. ________ is a perspective within psychology that emphasizes the potential for good that is innate to all humans, proposing a hierarchy of human needs in motivating behavior. C. b. \, 4,83,169,3227,-4,-\frac{8}{3},-\frac{16}{9},-\frac{32}{27}, \ldots Recall, from Chapter 13, that larger margins of error make it much more probable that the conclusion of an inductive generalization is true; there is a much greater chance that between 50 percent and 60 percent of the voters favor Jones than there is that exactly 55 percent of them do. The explanation is more probable than the leading alternatives. We typically favor the explanations with the highest prior probability. The second premise states that the observable outcome has happenedthat it has been observed. d. Aggression facilitates performance only in team-sport athletes. This helps to explain why so-called anecdotal evidence can be problematic. In an experiment, the group of subjects not exposed to the treatment being studied but otherwise treated identically to the experimental group. Muluple Choice Young women purchase fewer meats than women who are 35 years of age or older. Rabinoff claimed that this was evidence for a causeeffect relationship between TM and the weather. Treatment: in a research study, any condition applied to subjects - those in the treatment group - that is not applied to subjects in a control group. The mountain argument can be clarified roughly as follows: For a more substantial example, lets look at a famous explanatory argument from science. Psychoanalytic theory focuses on ________ and early childhood experiences. For general explanations, the simplest one normally predicts the smoothest curve. b. trained counselors But suppose I offer the alternative explanation that air pressure is highly irregular but that it so happens that barometric pressure nevertheless would be 30 inches at 0 feet, 28.7 inches at 1,300 feet, 28.2 inches at 1,800 feet, 27.2 inches at 2,800 feet, 26.2 inches at 3,800 feet, and 25.2 inches at 4,800 feet. It makes no statement with respect to causation. Why would you try to persuade your friend of something you have both just agreed is true? But the first one, Torricellis, has a higher prior probability because it is simpler, due to its prediction of a smoother curve. For exactly the same reason, we can hardly consider astrology to be supported when someone finds that the days horoscope has some truth in it; horoscopes are worded so vaguely that there are almost always events that can be interpreted as making them true. Because the observable outcome rules out the leading alternative explanations, its prior probability is far lower than the anecdotal argumentand thus the argument is logically much stronger. B. The following are illustrative examples of explanatory power. It includes the presumption of causation. More subtle examples are easy to find. In short, coincidence has not been ruled out, so we cannot judge this to be a logically strong argument. A hypothesis is a tentative explanation . For the sake of illustration, I will slightly idealize the intermediate readings: say, it was 28.2 inches at 1,800 feet, then one inch lower at each of the next thousand-foot intervals. When established scientists reject offbeat theories, defenders of such views love to cite these cases. Which of the following is an example of an objective measure used by functionalists? C. An increase in family income leads to an increase in the percentage of income spent on housing. A medical student has been reading intensively about various diseases of the nervous system. As with the outcome, the concern here is also with prior epistemic probabilityin this case, the probability that you would assess to the explanation prior to your making any judgment about the observable outcome. Experts are tested by Chegg as specialists in their subject area. Examples of this abound, even in some of the most widely accepted explanatory theories. She is a ________. William James was the ________. The explanation must be sufficiently probable. From 20 percent to 25 percent more eggs under the filters hatched successfully than those that were unshielded. , I can remember, not long ago, listening to a pal rail about a mutual friends apparently overwhelming need to flirt with every man in a given room. Young women purchase fewer meats than women who are 35 years of age or older. Archeologist Donald Grayson of the University of Washington has found some evidence in the Donner Party catastrophe. Note: See Section 6. The argument concludes with the assertion of the explanation. Alternative explanation that already exists. Another contemporary of his, French mathematician and philosopher Blaise Pascal, suspected that Torricelli was right but that a greater altitude was required to prove it. A. A. When an explanations prior probability is extremely low, another alternative explanation is deception. A It includes the presumption of In Maslow's hierarchy of needs, the ________ include food, water, and shelter. The experimental subjects do not know which (if any) treatment they are receiving. . In the study of personality, the ________ model includes dimensions of conscientiousness, agreeableness, neuroticism, openness, and extroversion. This disregard for weather extended even to the pouring of concrete. Concrete, according to the campus architect, was poured whenever the schedule required and the necessary materials were available. If hes her father, then he will go to great lengths to take care of her. a. But where the two species competed for seeds, one evolved a beak suited for the small seeds, while the other developed a beak for the large seeds. An explanation that is designed to apply only to a single thing or event. Carl Hempel, The Philosophy of Natural Science. c. fans are not affected in terms of aggressive tendencies by watching a sporting event Suppose Halley had decided to look for confirmation of Newtons celestial mechanics by studying the sun rather than comets and, based on Newton, had confidently predicted that the sun would rise the next day. The set of analytical and mathematical tools designed to help researchers gain understanding from the data they gather is called. Do not worry for now whether the observable outcome A Guide to Good Reasoning: Cultivating Intellectual Virtues by David Carl Wilson is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License, except where otherwise noted. What is the MOST IMPORTANT flaw in this investigation? Which system accumulates the costs for each department or process within the factory? 1) A complex, ordered organization consisting of one or more cells. There we have the marine. When I take a lot of vitamin C I do get fewer colds than normal. her own conscious experience. The arguer must have imagination to devise an explanation that is something more than a generalization of the experienced facts; and the evaluator must have imagination to think up viable alternative explanations for the sake of comparison. How often do plumbers waste time by doing things such as drying their clothes when they can make more money by going on to another job? In an experiment, the group of subjects exposed to a particular treatment; also known as the treatment group. And it contains the two essential components of an explanatory argument. There are a few money managers who succeed on the basis of skillmultibillionaire Warren Buffet is the most famous example. It will be proven when I get some sort of raise in the next few years. Young women purchase fewer meats than women who are 35 years of age or older. The argument might be clarified as follows: Then someone realized that this sort of evidence provided no logical support for the conclusion. The plumber explanation is burdened with improbabilities: The answer in each case is very infrequently. D. It excludes the presumption of The only difference is that Geller claims that he is not using deception. Applying Newtons laws to these data, he boldly made the following prediction: A comet with an orbit similar to the 1530 and 1606 comets will appear in December 1758. Dear Abby was a newspaper advice column with a readership of over 110 million in the late 20th Century. Which of the following refers to a broad explanation or group of explanations for some aspect of the natural world that is consistently supported by evidence over time? A theory has been extensively tested and is generally accepted among a set of scholars; a hypothesis is a speculative guess that has yet to be tested. The deception explanation should often be considered, but it is subject to the same high standards that apply to any other explanatory argument. Any performance significantly better or worse than the students current mean level of competence would be largely a matter of chance. c. Aggression sometimes facilitates performance and sometimes does not. A measurable entity that is created by the process being observed and whose value cannot be controlled; generally represented on the y- axis in a graph and expected to change in response to a change in the independent variable. This is what happened with Torricellis hypothesis. Slightly less oxygen means that we get tired a little sooner; slightly worn brakes stop the car a little more slowly; slightly less sunlight means the plant grows a little shorter. Step 1. Circles that had only later begun to appear elsewhere, they suggested, were created by copycats. a. assertive behavior. 1. . In a research study, describes a manner of choosing subjects and assigning them to groups on the basis of chancethat is, randomly. This condition is the logical requirement on any inductive argument that its conclusion fit appropriately with the total available evidence. An increase in family income leads to an increase in the percentage of income spent on housing. If the answer is yes, then the argument is at least moderately strong (assuming it has not failed the first part of the total evidence condition). It makes no statement with respect to causation. This is an example of. My iPhone will run out of power within the next 12 hours. This is a way of emphasizing the importance of an improbable outcome. (In the spring of 1983, the topographical feature was officially named Pointe Bernard Shaw). That should prove to you that it is running low. For each of the passages below, (i)state the observable outcome and (ii)offer a different observable outcome that would rule out alternative explanations and lower its probability, thus making the argument logically stronger. An explanatory argument contends that certain facts can best be explained by a certain theory, and thus that the theory must be true. 2003-2023 Chegg Inc. All rights reserved. To simplify, Halley wondered about the following statement: Newtons account of celestial mechanics is correct and, in particular, applies to the motion of comets. Exp. How does Abbys conclusion fare in the face of this alternative explanation? In science, theories tend to be ___________ than hypotheses. Select the correctly ordered list of psychological perspectives, with the earliest perspective listed first. Appetite fails, and the relatives keep water cans beyond reach, despite temperatures well above 100 degrees in the shade. Competition for food among finches on Galapagos causes the extremes in beak sizes. The irrational belief that actions not related by logic to a course of events can influence an outcome. Newsweek, Sample answer.
