1-41) In a scientific investigation, the variable that is measured by the investigator and is presumed to be the result of the manipulated variable is known as the a. independent variable. b. dependent variable. c. control variable. d. confounded variable. 1-42) The research strategy that makes use of independent and dependent variables in an attempt at inferring causal relationships is the a. descriptive study. b. correlational study. c. experiment. d. survey. 1-43) Davida has agreed to participate in a psychological study to earn extra credit in her introductory psychology course. When she arrives for the study, she notices that the testing room is white, very quiet, and highly controlled. The researcher randomly assigns her to a testing condition by flipping a coin. Most likely, Davida appears to be participating in a(n) a. descriptive study. b. correlational study. c. experiment. d. quasi-experiment. 1-44) In a study on memory, Professor Roberts randomly assigns his subjects to one of two different groups: a group that is given 10 minutes to study a list of spelling words, and a second group that, while treated identically to the first group, does not receive a 10-minute study session. Following this, a spelling test was given to both groups to assess the level of spelling mastery. In this example, the first group would be considered the __________, while the second group would be considered the __________. a. experimental; control b. control; experimental c. experimental; quasi-experimental d. quasi-experimental; control 1-45) In experimental studies, the __________ group receives the treatment or manipulation, while the __________ group does not. a. experimental; control b. control; experimental c. experimental; quasi-experimental d. quasi-experimental; control 1-46) In trying to remove bias in an experiment, researchers often make use of __________ in an attempt at making different groups equivalent. a. pseudoscience b. correlational studies c. random assignment d. introspection 1-47) Which of the following is NOT a criterion for establishing cause-effect conclusions? a. Covariation of variables b. Causal time sequence c. Elimination of other plausible causes d. Strong, positive correlations of at least +.80 1-48) __________ research designs examine differences among different groups but often fail to meet one or more criteria for inferring causation between the independent and dependent variables. a. Descriptive b. Correlational c. Experimental d. Quasi-experimental 1-49) Which of the following correlation coefficients represents the strongest relationship between two variables? a. +.75 b. -.10 c. +.80 d. -.90 1-50) Which of the following research designs assesses the degree and direction of statistical association between variables? a. Descriptive strategy b. Correlational strategy c. Experimental strategy d. Quasi-experimental strategy 1-51) Dr. Morova is involved in a research study that has as its goal the categorization of violent acts committed by players in a football game. Furthermore, he wants to chart the course of the violent acts as the season progresses. What type of study is Dr. Morova most likely conducting? a. Descriptive b. Correlational c. Experimental d. Quasi-experimental 1-52) While, theoretically, it is possible to infer causation from any research design, which design represents the least likely chance of producing cause-effect conclusions? a. Descriptive b. Correlational c. Experimental d. Quasi-experimental
