Jenny recently learned of plans to cut down an old beautiful tree on her campus to make way for a new bike path. Jenny is opposed to cutting down the tree, and she decides to survey some students at her university to see if others also oppose cutting down the tree. She plans to share the results of her survey with the school administration to argue to keep the tree. One question on Jenny's survey asks, "Would you be in favor of brutally cutting down this majestic tree to make way for a stupid bike path?" A problem with this question is that it is a _______________.
Leading Question

Dr. Lawrence is the director of Counseling Services at her university. She is planning to conduct a survey of 100 students at the university to see how aware they are of the counseling services that are offered at the university. She wants the proportion of males and females in her sample to reflect the proportion in the university as a whole (55 percent female and 45 percent male). Dr. Lawrence plans to stand in the Student Union and ask people to participate until she has given the survey to 55 females and 45 males. Is Dr. Lawrence collecting a representative sample? Yes, because the sample includes a representative proportion of males and females. Yes, because all of the students in her sample attend her university. No, because the participants are selected nonrandomly. No, because 100 people is not enough for a representative sample.
No, because the participants are selected nonrandomly.
Masked, or blind, study designs are designed to deal with:
Observer Bias
A study by Rosenthal and Jacobson (1968) involved telling teachers that some of their students were "bloomers" and would achieve rapid academic success within the next year. In fact, these students were no different than any of the other students in the class. At the end of the year, the "bloomers" showed more gains in IQ than the other students. It appeared that the teacher had unintentionally treated the "bloomers" in special ways. This is an example of which of the following?
Observer effects

On a scale of 1 (Strongly agree) to 5 (Strongly disagree) scale, rate the following statement: Computer games are a great pastime. On a scale of 0 (Not at all) to 5 (Very much), rate how much you like and play your favorite game.

Given the scenario above, Dr. Ewell is concerned that the children will behave differently because of the presence of research assistants. He is concerned about:
Reactivity
Convenience sampling relies on which of the following?
Studying people who are easy to find
The campus safety committee has asked Professor Ibrahim to study bicycling on his campus. He trains two observers and has them observe the number of cyclists and their safety at various points around campus. After completing the observational study, Professor Ibrahim sends a survey out to the entire campus about bicycle safety, and asks all bicyclists to respond. He finds a large difference between their reports of how safely they ride and what his observers found. What is the most likely cause of the self-report ratings being inconsistent with the observational data?
The bicyclists were probably responding in a socially desirable way on the self-report survey.
Which of the following is true regarding interrogating frequency claims? Their accuracy can usually be determined. The chief concern is to evaluate the sampling technique. The most important thing to consider is the size of the sample. Frequency claims cannot be interrogated.
The chief concern is to evaluate the sampling technique.
The campus safety committee has asked Professor Ibrahim to study bicycling on his campus. He trains two observers and has them observe the number of cyclists and their safety at various points around campus. When the observations began, the observers noticed that bicyclists slowed down when they neared the observers. How could this reactivity be avoided? The observers could use a blind study design. The observers could use random assignment. The observers could make unobtrusive observations by hiding. The observers could use a masked design.
The observers could make unobtrusive observations by hiding.
Why are double-barreled questions problematic?
They may have poor construct validity.
Which of the following is true about open-ended questions? They are more efficient than asking forced-choice questions. They are the most common format for psychologists to ask questions. They completely lack construct validity. They provide rich data, but they can be time-consuming for researchers because the responses need to be coded.
They provide rich data, but they can be time-consuming for researchers because the responses need to be coded.
Is it ethical for psychological researchers to observe people in a public place? No, because informed consent cannot be obtained from those being observed. Yes, because in those settings people can reasonably expect their behavior to be public, not private. No, because the researchers will have to individually identify the people they observe. Yes, because as long as it is for the sake of science, it is ethical to observe people in public or private places.
Yes, because in those settings people can reasonably expect their behavior to be public, not private.
Dr. Fletcher is concerned about a fence-sitting response set when he conducts his survey. Which of the following might you recommend to decrease fence sitting?

Mr. Stratford is the president of a national organization of lesbian, bisexual, gay, and transgender people in the United States. He wants to survey 1,000 members of his organization about the position they want the organization to take on several political issues. He knows that transgender people make up only 5 percent of his organization, but he wants to make sure that their views are accurately represented. He decides that he will randomly sample 100 transgender members and then adjust the final results so that transgender people are weighted to their actual proportion in the organization. Is Mr. Stratford collecting a representative sample? Yes, because 1,000 people is enough to make a representative sample. Yes, because the transgender people in the final sample were sampled randomly from the population of transgender people in the organization. No, because the transgender people are over-represented in the final sample. No, because straight people are not included in the sample.
Yes, because the transgender people in the final sample were sampled randomly from the population of transgender people in the organization.
Which of the following is true of a nonrepresentative sample in a research claim? You should automatically disregard the claim. You should automatically accept the claim. You should ask whether it is relevant to what the researchers are measuring. You should ask whether more participants are necessary.
You should ask whether it is relevant to what the researchers are measuring.
What kind of sample is best for external validity?
a sample where each member of the population has an equal chance of being selected
The superintendent of schools in a small town in Ohio made a lot of policy changes to the way school administration worked in his district. A researcher at a nearby university wanted to look at what teachers in his district thought about the changes. The researcher made a list of all of the schools in the district and used a random number generator to select a sample of five schools from the district. Then the researcher interviewed every teacher at each of those five schools. What sampling method did the researcher use?
cluster sampling
Typically, in which type of claim is it most important to have a random sample?

A college administrator knows that 70 percent of the students at his college are from out of state, so he decides to make sure that he includes 70 out-of-state students and 30 in-state students in his survey about admission practices at the college. He has a list of all of the out-of-state and all of the in-state students currently enrolled at the college. He randomly selects 70 students from the out-of-state list and 30 students from the in-state list. What sampling method is he using?
