a) What is the null hypothesis?

b) What is the alternative hypothesis?

c) What is the predictor variable?

d) What is the criterion variable?

List the descriptive and inferential statistics of the analysis

N = _____ Education: Mean/Standard Deviation = _____

Salary Mean/Standard Deviation = _____ Significance (p-value) = _____

Pearson correlation (r) = _____ Solve for effect size: r2 = _____

e) Do you reject or retain the null hypothesis?

f) Write the results as you would in the Results section of a journal article. Use correct APA format and include the descriptive statistics, type of statistical test, results of the test, and effect size.

g) Summarize your findings in a few sentences as in the Discussion section of a journal article.

A criterion variable is another name for a dependent variable. Here it is Salary.

List the descriptive and inferential statistics of the analysis

N =20

Variable Mean StDev
Years of Education 16.35 4.96
Salary 29420 12267

Correlations: Years of Education, Salary
