Using Chapter 13 Dataset 2 and SPSS, compute the F ratio for a comparison among three levels representing the average amount of time that swimmers practice weekly(<15, 15-25, and >35 hours) with the outcome variable being their time for the100-yard freestyle. Answer the question of whether or not practice time makes a difference.

the 3 levels of practice time for swimmers. Does practice impact swimming time? This is the problem on page 251 in the textbook. To do this you need to identify your dependent variable-what it is that you are looking for as an outcome.

What is the degrees of freedom for the numerator (k-1)?

What is the degrees of freedom for the denominator (n-k)?

Calculate the critical value for the ANOVA F-test at the .05 level using table B.3 on page 373-374 of the textbook

What is the conclusion that you can draw?

Using Chapter 13 Dataset 3 compute the F ratio for the stress levels of workers based on shift worked. Include descriptive analysis and a Bonferroni post hoc analysis.

First determine your dependent variable-this goes in the
