In the 2 x 3 ANOVA summary table below, with variables X (Stress-low/high) and Y (Money level), there is evidence of a: $50 $100 $150 Low Stress M = 85 M = 80 M = 75 Row 1 Mean = 80 High Stress M - 75 M = 70 M = 65 Row 2 Mean = 70 C1 M = 80 C2 M = 75 C3 M = 70 a. significant main effects for both stress and money b. significant main effect of money level c. significant interaction effect m d. significant main effect of stress and an interaction effect
Homework Answers

Correct Answer
Explanation: There is no interaction effect with
money being the only independent variable and stress being the
dependent variable. There is a marked increase in stress, both high
and low in the lower end of the money.

A psychologist was interested in the effects of age and stress on memory. Her rationale was that memory would become impaired following a stressor, and this would be excerbated with increasing. She recruited 48 participants: 24 young (ages between 18 - 35) and 24 old (ages between 55 - 72). Both young and old participants were randomly assigned to one of three stress conditions: Control (sitting in a quiet room); Low stress (listening to a 1 hour Hillary Clionton speech);...

12. Measuring effect size for two-factor ANOVA It is projected that approximately 580,000 veterans will take advantage of the GI Bill for the 21st Century. Boots to Books is a course for all veterans, current military members, and their family members, friends, and supporters. The goal of Boots to Books is to assist deployed, postdeployed, and veteran students in making a positive transition from military to civilian life or from deployment to postdeployment life, including the acquisition of college survival...

A researcher in Wyoming is investigating which factors influence people's decision to honk their car horns in frustration. In a study, male or female staff who were driving low quality or high quality cars pulled up to a stop light, then remained stationary after the light turned green. They measured the delay (in seconds) until the car behind them rger numbers mean they took longer to honk, small numbers mean they honked quickly Factor B- Gender M=10.17 T= 122 SS-5.67...
