Imagine that you are an awesome student in PSY362 this quarter (fingers crossed this is not much of a stretch to imagine) and you just got back your Quiz #1 grade. You received a 74% on this quiz. You are curious about how you did in relation to the rest of the class, and want to know your percentile rank within the class. You jotted down the mean and standard deviation for the quiz that your professor posted and now want to see how you performed on the quiz compared to the rest of the class. X = 79.90 X = 74.00 SD = 13.60 1) First compute your z-score, then identify your percentile rank in the class (remember to show all of your work!): You just found out that another student in the class, your nemesis (fictional examples: Susan, the loud breather, too much cologne guy), did better than you on this quiz, getting a 77%. However, both of you and your nemesis are also in the same Organic Chemistry class, and you did better than your nemesis on a quiz in that class. Specifically, you scored a 78% and your nemesis scored a 72%. The descriptive statistics for the Organic Chemistry exam are as follows: X = 73.90 SD = 20.10 Figure out if you performed better than your nemesis averaging across both exams! 2) First, calculate the z-score for your organic chemistry test performance:

3) Next calculate the z-score that represents your nemesis' stats performance (mean and standard deviation are on the previous page) and the z-score that represents their chemistry performance: 4) Now, average the z-scores for each person to determine how each person performed, on average, on the quizzes combined: 5) Finally, compare these ultimate z-scores to determine who performed better. Also be sure to report how much better one performed compared to the other (hint: remember what the z-score represents!):
