Answers will vary. Sample Answer: One possibility is to obtain the class roster and assign each student a number from 1 to Then use a random number generator or table of random number to generate 30 numbers between 1 and , and select the students matching the random numbers. One possibility would be to obtain a roster of students enrolled in the college, including the class standing for each student. Then you would draw a proportionate random sample from within each class for instance, if 30 percent of the students in the college are freshman, then 30 percent of your sample would be drawn from the freshman class. For the first person picked, the chance of any individual being selected is one in For the second person, it is one in , for the third it is one in , and so on. For the 30th person selected, the chance of selection is one in There are at least two chances for bias.- First, the viewers of this particular program may not be representative of American football fans as a whole. Second, the sample will be self-selected, because people have to make a phone call in order to take part, and those people are probably not representative of the American football fan population as a whole. These results 84 percent in one sample, 86 percent in the other are probably due to sampling variability. Each researcher drew a different sample of children, and you would not expect them to get exactly the same result, although you would expect the results to be similar, as they are in this case. The improvement could also be due to self-selection: only motivated students were willing to sign the contract, and they would have done well even in a school with 6.
- Because both changes were implemented at the same time, it is not possible to separate out their influence. At least two aspects of this poll are troublesome. The first is that it was conducted by a group who would benefit by the result—almond sales are likely to increase if people believe that eating almonds will make them happier. The second is that this poll found that almond consumption and life satisfaction are correlated, but does not establish that eating almonds causes satisfaction.
- It is equally possible, for instance, that people with higher incomes are more likely to eat almonds, and are also more satisfied with their lives. You want the sample of people who take part in a survey to be representative of the population from which they are drawn. People who refuse to take part in a survey often have different views than those who do participate, and so even a random sample may produce biased results if a large percentage of those selected refuse to participate in a survey. There are many lurking variables that could influence the observed differences in test scores.
- Perhaps the boys, on average, have taken more math courses than the girls, and the girls have taken more English classes than the boys. Perhaps the boys have been encouraged by their families and teachers to prepare for a career in math and science, and thus have put more effort into studying math, while the girls have been encouraged to prepare for fields like communication and psychology that are more focused on language use.
- A study design would have to control for these and other potential lurking variables anything that could explain the observed difference in test scores, other than the genetic explanation in order to draw a scientifically sound conclusion about genetic differences. To use random assignment, you would have to be able to assign people to either smoke or not smoke. Because smoking has many harmful effects, this would not be an ethical experiment. Instead, we study people who have chosen to smoke, and compare them to others who have chosen not to smoke, and try to control for the other ways those two groups may differ lurking variables.
- Sources of bias include the fact that not everyone has a telephone, that cell phone numbers are often not listed in published directories, and that an individual might not be at home at the time of the phone call; all these factors make it likely that the respondents to the survey will not be representative of the population as a whole. Research subjects should not be coerced into participation, and offering extra credit in exchange for participation could be construed as coercion. In addition, this method will result in a volunteer sample, which cannot be assumed to be representative of the population as a whole. The value is an outlier, because the exams were graded on a scale of 0 to , and is far outside that range.
- It may be a data entry error, with the actual score being 74, so the professor should check that exam again to see what the actual score was.
