• For what types of data would you use nonparametric versus parametric statistics?
• Briefly describe the difference between internal and external validity.
• When a researcher has an accidental or convenience sample, what kind of population can he or she try to make inferences about?
• For each of the following lists of scores, indicate whether the value of SS will be negative, 0, between 0 and +15, or greater than +15. (You do not need to actually calculate SS.)
• Sample A: X = [103, 156, 200, 300, 98].
• Sample B: X = [103, 103, 103, 103, 103, 103].
• Sample C: X = [101, 102, 103, 102, 101].
