Sage Final Exam Questions with Correct Answers 100% Verifed 2024 the simplest possible kind of true experiment is ___ -a one-group design -a two-groups design -a one-way design -a 2 X 2 factorial design - Correct Answer a two-groups design The major limitation of one-way experimental designs is that they only allow researchers to look at one ______ at a time.-independent variable -dependent variable -control group -treatment condition - Correct Answer independent variable How many cells (i.e., how many unique experimental conditions) are there in a 2 x 2 x 3 completely between-subjects factorial experiment?-6 -7 -12 -there is no way to tell without knowing more about the design - Correct Answer 12 In the Gilbert et al. (1988) study of causal attribution discussed in the text, the researchers independently manipulated cognitive load (low vs. high) and discussion topics (anxiety-provoking vs.relaxing). Thus, the design of this study was ______.-a one-way, four-groups design 1 / 3
-a latin square factorial -a mixed-model design -a 2x2 factorial design - Correct Answer a 2x2 factorial design In a 2 x 2 factorial study, what is the maximum number of main effects that you could possibly observe?-one -two -three -four - Correct Answer two If you overheard a researcher say that "each of the three possible main effects in my study was significant," you could conclude that the analysis the researcher had conducted was ______.-a one-way, three-groups anova -a two-way anova -a three-way anova -a planned comparison - Correct Answer a three-way anova Is it possible for a statistical analysis to yield three main effects in a 2 x 2 factorial study?-no, because there are only two independent variables -no, because there are only two cells in such a design -yes, but only if the test for an interaction is significant -yes, but only if the test for an interaction is not significant - Correct Answer no, because there are only two independent variables If you plotted the results of a factorial study using lines whose slopes represent mean differences across different experimental conditions, the presence of a statistical interaction would show up in the form of
______. 2 / 3
-lines that are separated by a statistically significant distance -lines that generally slope upward -lines that generally slope downward -nonparallel lines - Correct Answer nonparallel lines Consider the findings of the hypothetical study of plant growth summarized below (and in your text): Amount of Sunlight Received Amount of Water Received Low High Row Means Low 22.4 25.6 24.0 High 10.8 37.2 24.0 Column Means 16.6 31.4 This study appears to have yielded ______.-only a main effect of sunlight -only a main effect of water -both a main effect of sunlight and a sunlight x water interaction -both a main effect of water and a sunlight x water interaction - Correct Answer both a main effect of sunlight and a sunlight x water interaction a disordinal interaction is the same as _______.-a crossover interaction
