Project 3 – SPSS Analyses
Before beginning this assignment, be sure to watch the MindTap SPSS Demonstration Library
videos corresponding to each question in order to successfully complete the assignment. The
videos and links are listed in the LMS assignment description and below each question.
In SPSS run the correct statistical test for each study.
1. A researcher is interested to learn if there is a linear relationship between the hours in a
week spent exercising and a person’s life satisfaction. The researchers collected the
following data from a random sample, which included the number of hours spent
exercising in a week and a ranking of life satisfaction from 1 to 10 (1 being the lowest
and 10 the highest).

a. Run descriptive statistics on the data. Report the mean, variance and standard
deviation for the data of hours of exercise per week by the participants. Copy
and paste the SPSS output into the word document.
b. Run a bivariate correlation to determine if there is a linear relationship
between the hours of exercise per week and life satisfaction. In 3-4 sentences
interpret the results in words, then write the statistical results in APA
style. Report the Pearson’s Correlation and probability statistic.
2. Insomnia has become an epidemic in the United States. Much research has been done in
the development of new pharmaceuticals to aide those who suffer from insomnia.
Alternatives to pharmaceuticals are being sought by sufferers. A new relaxation
technique has been tested to see if it is effective in treating the disorder. Sixty insomnia
sufferers between the ages of 18 to 40 with no underlying health conditions volunteered
to participate in a clinical trial. They were randomly assigned to either receive relaxation
treatment or a proven pharmaceutical treatment. Thirty were assigned to each group. The
amount of time it took each of them to fall asleep was measured and recorded. The data is
shown below.
a. Run a two-independent samples t-test to determine if the relaxation treatment is
more effective than the pharmaceutical treatment at a level of significance of 0.05.
Copy and paste the SPSS output into the word document.
b. In 3-4 sentences interpret the results in words, then write the statistical
results in APA style. Report the t statistic and probability statistic. MindTap

3. A researcher is interested to learn if the level of interaction a woman in her 20s has with
her mother influences her life satisfaction ratings. Below is a list of women who fit into
each of four levels of interaction. Conduct a One-way Between Subjects ANOVA on the
data to determine if there are differences between groups; does the level of interaction
influence women’s ratings of life satisfaction?

a. Report the results of the One-way Between Subjects ANOVA. If significance is
found, run the appropriate post-hoc test and report between what levels the
significant differences were found. Copy and paste the SPSS output into the
word document.
b. In 3-4 sentences interpret the results in words, then write the statistical
results in APA style. Report the F statistic and probability statistic.

4. A researcher is interested in studying the effect that the amount of fat in the diet and
amount of exercise has on the mental acuity of middle-aged women. The researcher used
three different treatment levels for the diet and two levels for the exercise. The results of
the acuity test for the subjects in the different treatment levels are shown below.
