In this unit we have worked with scores and their locations within a distribution. This discussion is designed to get you to think a little more about distributions of scores. Shown below are two samples of scores. Input these scores into SPSS and use plots and data descriptions to see if you can guess which sample of scores is a random sample of scores from a population that has a normal distribution with a mean of 80 and a standard deviation of 20. Leave a discussion message that describes your methods and whether you think sample A or sample B is most likely to have come from the population I just described. Explain your reasons. Check back to see if your classmates arrived at the same conclusion. After reading several other posts describe why you would stick with your original answer or change it now that youâ€™ve read answers from other people.
