4. A school psychologist is interested in determining whether children who attend public schools have poorer self-esteem than children who attend private schools. The psychologist obtains a list of the public schools and a list of the private schools in the immediate area and then randomly selects 5 public schools and 5 private schools from the respective lists.

This type of sampling method is called _________________. a. stratified random sampling. b. cluster sampling. c. purposive sampling. d. convenience sampling.
B (cluster sampling: a sampling procedure in which units (e.g., geographic regions, schools) that contain members of the population are identified. These unitsÑcalled "clusters"-are then randomly sampled, and within each sampled cluster either all members or randomly chosen members are selected to participate in the study.)
13. A group of psychologists have decided to conduct a study with a sample of 200 students from a local elementary school, which is made up of 75% girls and 25% boys. In order to accurately reflect the gender composition of the school, the researchers decide to select 150 girls and 50 boys. They then use simple random sampling to select the participants. This sampling procedure is called ____________ sampling. a. random cluster b. stratified random sampling c. quota sampling d. purposive random sampling
B (stratified random sampling： a sampling technique in which a sampling frame is divided into groups (called strata; singular = stratum), and then within each group random sampling is used to select the members of the sample.)

B（ Sensitive questions usually come in the middle, after rapport has been established.）
Which of the following would NOT be a benefit of strong visual presentation and careful formatting of a survey? a. A strong visual presentation communicates that you are professional and care about your work. b. Strong visual presentation and careful formatting can help interviewers easily move through the survey. c. Strong visuals and careful formatting always shorten the survey, increasing the response rate. d. Good attention to visual presentation can influence participants to complete the survey.
C
10. A company asked their employees to answer the following question: "Do you agree or disagree that gossiping and inter-office affairs are a problem?". The major problem with this question is that it is a ___________ question. a. double negative b. leading c. double-barreled d. loaded

1. A psychology professor decides to study the prevalence of plagiarism on campus and decides to select 1000 participants randomly from the study body. The professor contacts the college registrar and asks for information regarding the percentages of students who are male and female and who are Caucasian, African-American, American Indian, and Asian-American. Based on this information, the psychologist randomly selects a sample that is similar to the student body in terms of sex and race. With regard to these characteristics, the group of participants in this study would be a ______________ sample. a. clustered b. demographic c. representative d. quota
C (representative sample: a sample that reflects the important characteristics of the population.)

D
4. Which of the following is NOT true about non-probability sampling? a. It is less costly than probability sampling. b. It is more common than probability sampling. c. The probability of a population member being selected often cannot be determined. d. It relies on statistical theory.
D
8. One of the items on a scale asks participants to indicate how important their autonomy is to them. The possible responses are 1 (very unimportant), 2 (somewhat unimportant), 3 (neither important nor unimportant), 4 (somewhat important), and 5 (very important).

D
Stratified random sampling is the preferred strategy when: a. only a part of the population is accessible to researchers. b. the population is very small. c. no sampling frame is available. d. you want to include specific subgroups in the study.
D
Surveys often use a matrix format. The major benefit of this format is that it: a. makes the language of the items less complex. b. is more readable than other formats. c. requires less effort from the participant to respond. d. saves space in the questionnaire.
D
Systematic sampling can produce a very biased sample when: a. the population is too small. b. there is no available sampling frame. c. the population is too heterogeneous. d. there is a structure to the sampling frame.
D
The sequence of items in a survey is important because: a. participants often become tired when completing surveys. b. items should always progress from more general items to more specific items. c. surveys should always begin with background information. d. the content of previous items can bias later responses.

6. A political policy team is interested in determining how many people vote in national elections. They randomly select three nationally representative samples of 1000 people and get slightly inconsistent results. Specifically, the first sample suggests that 35% of people vote, the second reveals that 37% of people vote, and the third sample indicates that 33% of people vote. These chance fluctuations in the characteristics of a randomly selected sample are called: a. sampling error. b. random variability. c. probability error. d. sampling variability.
D （sampling variability： chance fluctuations in the characteristics of samples that occur when randomly selecting samples from a population.）
