Purpose
The purpose of this test is to test whether neuroticism, extroversion, and sex predict the
likelihood that a student would participate in your study. Based on my findings,
I will be able to
determine what types of students should be recruited for the study.
Method
The data for Lesson 10 Practical Exercise: Categorical Outcomes comes from the Cowles.csv
dataset provided in the lesson assignment. The variables that will be used will be
Volunteer
: 0 for
would not volunteer, 1 for would volunteer for the study which is the dependent variable, and the
other variables will be
Neuroticism
: Eysenck’s Personality Inventory measure of neuroticism. It
ranges from 0 (stable) to 24 (neurotic).,
Extroversion
: Eysenck’s Personality Inventory measure
of extroversion. It ranges from 0 (introverted) to 24 (extroverted)., and Sex: Female: 0 for male,
1 for female. The Cowles.csv dataset will be put into JASP and a Logistic Regression will be
conducted with (volunteer) being the dependent variable and Neuroticism and Sex being the
Covariates. A Logistic Regression will also be conducted for Extroversion as well using the same
steps as was done for Neuroticism. Conducting these tests will determine whether a neuroticism
or extroversion student should be recruited for the study.
Results
As you can see in figure one for Logistic Regression for Neuroticism it is indicated that the P
value for the volunteer was 0.001 and is Less than 0.05 this means that there is a relationship
with the variables that are being tested. The P Value for neuroticism is 0.954 and is greater than
0.05 meaning that there is no relationship between the variables being tested. The P value for Sex
is 0.024 and is less than 0.05 meaning that there is a relationship between the variables being
tested. As for the standard error and odds ratios as you can see in figure one the intercept
standard error is 0.143 and the odds ratio is 0.627 meaning that it is greater than the standard
