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.

When they find the designated character, they press a button to stop a timer. Their reaction time (in ms)...
SPSS Homework 1 Instructions: Review and One-Way ANOVAs (40 points) Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember that we divide the p value in half when reporting one-tailed tests with 1 – 2 groups. Problem Set 2: Pearson’s correlation (7 pts) Research Scenario: Is there a positive relationship between...
