Variables in the working file
For each research question, describe in your Microsoft Word document the application of the seven steps of the hypothesis testing model.
Step 1: State the hypothesis (null and alternate).
Step 2: State your alpha (unless requested otherwise, this is always set to alpha = .05).
Step 3: Collect the data (use one of the data sets).
Step 4: Calculate your statistic and p-value. (This is where you run spss and examine your output files.)
Step 5: Accept or reject the null hypothesis. (This is where you report the results of your analyses t (df) = t-value, p = sig. level.)
Step 6: Assess the Risk of Type I and Type II Error. (Did the data meet the assumptions of the statistic, effect size, and sample size?)
Step 7: State your results in APA style and format.
