Describe how the following analysis of two-variable data may be affected by sample size and/or outliers. a. 888888 450 400 350 300 250 200 0 5 10 15 20 25 Figure 10 b. 25 20 15 10 10 5 0+ 0 5 10 15 20 20 Figure 11 5. The following are the entrance exam scores (percentages) of 15 randomly chosen students: 65 81 95 74 77 83 338 55 90 85 62 89 83 62 68 83 a. Calculate the mean, median and mode of the 15 scores. Round answers to the nearest whole number if applicable. b. Calculate the range of the scores. c. Determine the first, second and third quartiles. d. Calculate the percentile rank of a person who has a score of 62%. e. What is the score of a person who is in the 80th percentile of the data? 6. Seven out of every nine people do not floss regularly.
