9-31) In a 2 x 2 factorial interaction plot, if the two lines on the graph are completely crossed (forming an “X”), it would appear that the results could be summarized by saying that a. there is one significant main effect and a significant interaction effect. b. both main effects are significant and the interaction effect is significant. c. neither main effect is significant, but the interaction effect is significant. d. both main effects are significant, but the interaction effect is not. 9-32) In a 2 x 2 factorial interaction plot, if the two lines on the graph are sloped upward, not parallel, and separated vertically from each other, it would appear that the results could be summarized by saying that a. there is one significant main effect and a significant interaction effect. b. both main effects are significant and the interaction effect is significant. c. there is one significant main effect and no significant interaction effect. d. both main effects are significant, but the interaction effect is not. 9-33) In a 2 x 2 factorial design, if the 40 research participants are divided equally across the four conditions (i.e., 10 subjects per condition), the design could be labeled as a(n) a. all independent groups design. b. mixed design. c. all dependent groups design. d. none of the above 9-34) In a 2 x 2 factorial design, if the 10 research subjects participate in all four conditions, the design could be labeled as a(n) a. all independent groups design. b. mixed design. c. all dependent groups design. d. none of the above 9-35) In a 2 x 2 factorial design, if one of the independent variables is between-subjects in nature, and the second one is within-subjects in nature, the design could be labeled as a(n) a. all independent groups design. b. mixed design. c. all dependent groups design. d. none of the above 9-36) Dr. Roberts is a cognitive psychologist and she is designing a factorial study where she wants 30 subjects to be assigned to a 5-minute study condition and the same subjects to then be assigned to a 10-minute study condition. For the second independent variable, Dr. Roberts wants 15 of these participants to consume a cup of caffeinated coffee before studying, and the other 15 subjects to drink a cup of decaffeinated coffee before studying. This design is an example of a(n) a. all independent groups design. b. mixed design. c. all dependent groups design. d. none of the above 9-37) Dr. Sprague is a cognitive psychologist and he is designing a factorial study where he wants 30 subjects to be assigned to a 5-minute study condition and the same subjects to then be assigned to a 10-minute study condition. For the second independent variable, Dr. Sprague wants all 30 of these participants to consume a cup of decaffeinated coffee before studying, and then, later on, all 30 subjects to drink a cup of caffeinated coffee before studying. This design is an example of a(n) a. all independent groups design. b. mixed design. c. all dependent groups design. d. none of the above 9-38) Upon analyzing the data of a 2 x 3 factorial experiment, Professor Lange notes the following result from the computer output: F(3, 96) = 42.17, p < .01. What would Professor Lange conclude? a. This particular effect is statistically significant. b. This result is based on a nonparametric analysis. c. This result is based on an independent groups t test. d. none of the above 9-39) In factorial experiments, researchers are limited to __________ levels within any of the included independent variables. a. 2 b. 5 c. 10 d. none of the above 9-40) A “four-way” factorial design would have a. one independent variable with four levels. b. one independent variable with four dependent variables. c. four independent variables. d. two independent variables with two dependent variables.
