your interpretation on them. Please circle the key parts of the output that you discuss. Use the

output as in Output 6.1 by writing an explanatory paragraph as you would in the method section
of an article or paper.
6.2 Compute interrater reliability by running a paired t test for the essay score 1 with the essay

your results for this analysis as you would in the method section of an article or paper.
6.3 Run an Exploratory Factor Analysis using the extraction method of principal axis factoring
as demonstrated in Problem 6.3. Run the factor analysis on the 13 items related to stress. In the
extraction window (see Fig. 6.7), request “fixed number of factors to extract” as 2. Study your
output using the Interpretation of Output 6.3, make a table and write up your results as you

6. Use appropriate level headings for key elements of your discussion such as Research
