Question

For items 1-5 (2 pts each), use the following scores to calculate the descriptive statistics below: 2, 4, 6, 8, 8, 8

1.   Mean =                                                                        4. Standard deviation =

2.   Mode =                                                                        5. Degrees of Freedom =            

3.   Median =                                                                                                                        

For items 6-7, use the data from a standardized test (m = 75, s = 10) that measures superhuman power. In addition to calculations, be sure to complete the distribution below by labeling z scores, mean, and standard deviation (1 pt) AND drawing in where each individual’s score fall

Spiderman has a score of 78. What is his z score and percentile rank? Where does Spiderman fall in the distribution? (5 pts total)

      z score =                                                                      percentile rank =                                                                    

8.   Superman is at the 95th percentile. What is his z score and raw score? Where does Superman fall in the distribution? (5 pts total)

            z score =                      raw score =
