The following set of scores was collected on the number of hours spent on social media by students in a week:

11, 13, 14, 14, 15, 16, 17, 17, 18, 19, 20, 20, 21, 22, 22, 23, 23, 24, 24, 25

14) Which raw score is indicated at 45%? Use the formula shown in lectures

15) What is the percentile for 19 hours a week? Use the formula shown in lectures

16) Based on the previous example, construct a simple frequency distribution, a relative frequency distribution, a cumulative frequency distribution and a percentile

17) If you wanted to represent a distribution visually, how would you know if you should use a bar graph, pie chart, histogram or frequency polygon?

Formulas: P= i/n * 100

i = p*n
