What kind of correlation analysis would you conduct? Run the scatterplot with regression line, and descriptive statistics for both variables and document your findings (r and sig. [p value], ns, means, standard deviations) and hypothesis resolution.

Solve the following exercise from the Knapp textbook:

An exercise advocate wants to determine the relationship between walking rigorously and weight loss. He recruits participants to engage in a weeklong study. He instructs participants to take a brisk walk as many days of the week as possible for as long as they can. Participants will record the following data: weight prior to engaging in the walking regimen, the amount of time walked each day, and their weight at the end of the week. Participants will submit their data to the exercise advocate at the end of the week. The exercise advocate will preprocess the data to derive the total number of hours walked (walkhrs) and the change in weight for each participant (wtloss = weight at the beginning of the week – weight at the end of the week).

Conduct this analysis using SPSS: Exercise 8.1. Data file: Ch 08 – Exercise 01A.sav Download Ch 08 – Exercise 01A.sav

Answer the following:

(1) Write the hypotheses.

(2) Run the criteria of the pretest checklist (normality for both variables, linearity, homoscedasticity) and discuss your findings.

(3) What kind of correlation analysis would you conduct? Run the scatterplot with regression line, and descriptive statistics for both variables and document your findings (r and sig. [p value], ns, means, standard deviations) and hypothesis resolution.

(4) Write an abstract up to 200 words detailing a summary of the study, your statistical test, hypothesis resolution, and implications of your findings.
