Question: Calculate the Pearson r between stress and anxiety, using the formula presented in Exercise 28. List the SOLVED numerator and the denominator values (solve to completion).

Compute the Pearson r with SPSS. Paste the correlation matrix table into your homework.

What was the exact likelihood of obtaining the r value at least as extreme or as close to the one that was actually observed, assuming that the null hypothesis is true? (this question is asking you for the exact p value, converted to a percentage. Remember, p is NEVER, EVER zero!)

How would you characterize the magnitude of the effect between stress and anxiety? Refer to Table 28-1 for the size of the effect. State your rationale.

Write your interpretation of the results, as you would in an APA-formatted journal.

Help for Homework 3:

Please watch my video ‘What is a p value‘ in Module 2. When comparing the obtained r to the tabled r, the obtained must be higher than the tabled r to achieve significance. The other way to determine significance is to look at the exact p value presented in statistical software output. If the exact p is LESS THAN .05 then
the result is significant.

Q5: You want to pattern your interpretation exactly like that on page 342, top of the page. Two sentences: the first one reports the analysis performed, correlation value, df, and p. The second sentence should offer some explanation of the nature of the association- "Higher stress levels were associated with lower/higher.....
