Question

Data from 5.7:

Problem Set 5.7: Scatterplot in SPSS

• Criterion: Create a scatterplot using SPSS.
• Data: Dr T wanted to see if mindfulness 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. These were his results:

Minutes of Mindfulness Training	DRT Stress Inventory Score
61	8
122	6
201	3
133	9
55	7
329	1
10	9
1	10
93	7
144	5

Problem Set 5.9: Pearson r in SPSS (2)

• Criterion: Complete hypothesis testing and interpret correlational data.
• Data: Use the same data set from Problem Set 5.7.
• Instruction: Complete the following:

a.   Identify the null hypothesis.

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?

c.   Report the results as you might see them in a journal (i.e., in APA Style).

Answer 1

The scatter plot using SPSS is:

The hypothesis being tested is:

H₀: β₁ = 0

H₁: β₁ ≠ 0

The SPSS output is:

The p-value from the output is 0.000.

Since the p-value (0.000) is less than the significance level (0.05), we can reject the null hypothesis.

Therefore, we can conclude that mindfulness training is related to stress levels.
