Problem Set 5.9:

Pearson

r

in

SPSS (2) - (ignore the color and shading, please)

• Criterion: Complete hypothesis testing and interpret correlational data.
• Data: Use the same data set from Problem Set 5.3.
• Instruction: Complete the following:

a.Identify the null hypothesis.

H0: Practice of Mindfulness correlates with a reduction of stress

b.Answer this: Based on the correlation output (two-tailed test), can the null hypothesis be rejected? If the null can be rejected, how confident can you be that the results are not due to chance?

The null hypothisis can be rejected.99% confidence the results are not by chance.

c.Report the results as you might see them in a journal.

The practice of mindfulness correlates strongly negative with the reduction of stress, thus the null hypothesis can be rejected with a pearson coorelation of -0.9796 at the 0.01 level. There is a 99% confidence the result are not by chance.

I'm looking for feedback on the null null hypothesis - I feel like it should probably read "H0: Practice of mindfulness does not correlate with a reduction in stress."

0 Data: Dr T wanted to see if mindilness training is related to stress levels. He recruited 10 participants to undergo mindfulness training and examined their reported stress levels on the DRT Stress Inventory.
