- Select the two continuous variables
- Ensure Pearson is checked
- Click OK.
What should you interpret after running a Pearson correlation analysis?
Look for the correlation coefficient (r) and p-value.
What is the purpose of Partial Correlation Coefficient?
To examine the relationship between two variables while controlling for the effect of a third variable.
What steps are involved in running a Partial Correlation analysis?
- Click Analyze > Correlate > Partial
- Select the two variables of interest and the control variable
- Click OK.
What should you interpret after running a Partial Correlation analysis?
Review the partial correlation coefficient and p-value.
What is the purpose of Simple Linear Regression?
To predict the value of one continuous variable based on another.
What steps are involved in running a Simple Linear Regression analysis?
- Click Analyze > Regression > Linear
- Transfer the dependent variable to the Dependent box and the independent variable to the Independent box
- Click OK.
What should you interpret after running a Simple Linear Regression analysis?
Examine the R-squared value, coefficients, and significance of the model.
What is the purpose of the Mann-Whitney U Test?
To compare differences between two independent means.
What steps are involved in running a Mann-Whitney U Test?

- Choose Mann-Whitney U
- Click OK.
What should you interpret after running a Mann-Whitney U Test?
Review the U statistic and associated p-value.
What is the purpose of the Chi-Square Test of Independence?
To determine if there is a significant proportion/association between two categorical variables.
What steps are involved in running a Chi-Square Test of Independence?
- Organize data in a contingency table
- Click Analyze > Descriptive Statistics > Crosstabs
