Question: Use the following numbers: 48, 38, 15, 36, 25, 38, 48, 18, 34, 37. and assume the numbers represent scores on a posttest. Using these “scores,” give the formula, compute the following (show your work), and interpret each result:
* Mean - 10 points
* Median - 5 points
* Mode - 5 points
* Standard deviation - 10 points
* z scores, and - 10 points
* Pearson r (divide the column in half and make two columns of five scores each).
