250 words/ two scholarly sources due 12/2!

Each student will complete the following problems for the Unit Three Discussion post assignment:

1) Immediately following the reading of a social science unit, a class of 13 students takes a 20-item quiz on the material presented. Their scores, based on the number of items answered correctly, were as follows: 12, 12, 14, 15, 16, 19, 20, 10, 7, 5, 2, 3, 3. Find the mean, median, and mode and report them in your narrative discussion post.

2) A week later the same class of 13 students mentioned in the previous problem takes the same test a second time. This time their scores were: 11, 11, 11, 11, 12, 14, 20, 10, 10, 10, 9, 2, 8, 9. Find the mean, median, and fashion. Was there a difference in their performance when taking the test a second time?

Respond to the above two questions with a minimum of 250 words in a narrative format, supporting your post with two scholarly sources from the Library
