Overview
I'm working on a statistics multi-part question and need the explanation and answer to help me learn.
Scenario:
The data set you opened represents scores of 800 recent college graduates who participated in a study. First, participants were asked to control their emotions while watching a very sad movie, and then completed a challenging set of brain teasers. One week later, participants returned to the lab and again watched a sad movie. This time, they were not asked to control their emotions and completed a different (but equally challenging) set of brain teasers. In both cases, the researchers measured how much participants persisted at the difficult brain teasers. The variables in this data set are:
SUBJECT
Unique subject identifier from 1-800
PERSONALITY
Personality Type (0 = Introvert; 1 = Extrovert)
CTRL_PER
Persistence after watching a sad movie and being asked to control emotions (1-10 scale; higher numbers indicate greater persistence).
NO_CTRL_PER
Persistence after watching a sad movie and NOT being asked to control emotions (1-10 scale; higher numbers indicate greater persistence).
NEED_CTRL
Self-report of need for control in the environment, measured two months before participating in the study (1-5 scale; higher numbers indicate greater need for control over one's environment)
JOB
First job or activity following college graduation (0 = Public service job; 1 = Graduate school; 2 = Travel; 3 = Private sector job)
What statistical test to use? (SPSS data, output.spv file, can be provided)
Q1) Do introverts and extroverts differ in their need to control their environment?
Q2) Does persistence after watching a sad movie and being asked to control emotions vary depending on job plans?
Q3) Is the self-reported need to control one’s environment associated with persistence scores when participants did not control their emotions after watching a sad move (variable NO_CTRL_PER)?
