SOLVED

10-41) Trish has put her name on a list as a potential volunteer for a research study. She knows that the list will eventually contain 100 names and that the study will make use of 25 of those volunteers. Hence, Trish’s chances of being in the study will be 1-in-4. This type of a sampling strategy is referred to as a. probability sampling. b. nonprobability sampling. c. stratified random sampling. d. cluster sampling. 10-42) In probability sampling, the list of all individuals from which the sample will be selected is known as the a. population. b. sampling frame. c. experimental group. d. participant pool. 10-43) In selecting representative samples, the technique that specifies that every individual has an equal chance of being included in the sample is known as a. simple random sampling. b. stratified random sampling. c. cluster sampling. d. nonprobability sampling. 10-44) In selecting representative samples, the technique that specifies that the sampling frame is broken up into sub-groups before random selections are made is known as a. simple random sampling. b. stratified random sampling. c. cluster sampling. d. nonprobability sampling. 10-45) In selecting representative samples, the technique that specifies that the researcher begins by identifying a large number of units of individuals who have a feature in common, and then randomly selects some of those units, is known as a. simple random sampling. b. stratified random sampling. c. cluster sampling. d. nonprobability sampling. 10-46) In general, researchers will often use __________ when they don’t have access to a sampling frame, but are trying to construct one. a. simple random sampling b. stratified random sampling c. cluster sampling d. nonprobability sampling 10-47) In __________, researchers cannot derive a sampling frame nor can they determine the likelihood of any individual from the target population being included in the sample. a. simple random sampling b. stratified random sampling c. cluster sampling d. nonprobability sampling 10-48) Dr. Marcus is conducting a study and he recruits subjects from his introductory psychology class. This type of sampling strategy is best characterized as a. simple random sampling. b. stratified random sampling. c. cluster sampling. d. convenience sampling. 10-49) In determining how many subjects to include in a study, researchers need to consider three factors: 1) the alpha level to be used; 2) the desired power of the analysis; and 3) the a. expected effect size. b. geographic location of the study. c. significance level of the results. d. precision of the dependent measure. 10-50) In terms of assigning subjects to different treatment conditions, researchers should try to a. recruit as few subjects as possible. b. make use of animal subjects as often as possible. c. make the number of subjects as similar as possible in all groups. d. deceive the subjects as much as possible in order to maintain high levels of accuracy.
