What kind of t test would you use to analyze the data? How do you know? 2. Generate the hypothesis for this t test using the variables named in the graph. 3. Scroll down to the chart that shows distribution of sleep. What do you think about the homogeneity of variance of the two distributions? Would it meet or violate the assumption? 1. If it were violated and the data were in SPSS, what would you do to account for the violation? Your book discussed the conditions under which you would perform an independent samples t test and a one-way ANOVA. The hypotheses for these tests were also discussed. In this activity, you will apply this information.

Pretend you are investigating this shoe-coming-undone phenomenon. Assume the dependent variable is number of times each knot comes untied, and each person in your (imaginary) study was randomly assigned to tie their shoe using one of the knots only. 1. Generate a hypothesis using the available knots as groups. Use the term mean differences in your hypothesis. 2. What type of test would you use to test the hypothesis?
