Step 1: State your null and alternative hypothesis
Step 2: State your critical value. What is your alpha level? Is this one-tailed or two-tailed? How many degrees of freedom?
Step 3: Compute the appropriate statistic for an obtained score
Step 4: Make your decision, should you reject or fail to reject the null hypothesis? What can you conclude? (3 points) Should you compute effect size? If so, do it! What do you conclude from this statistic? - Of course, you should also report the appropriate proportion of variability
Write a formal paragraph to interpret your scores.(5 points)
