In this project Olivia and I surveyed the junior and senior class on how many sweatshirts they owned. We decided to use systematic sampling to choose who we would survey. We found the mean, median, mode, range, trimmed medians, the variance, standard deviation, coefficient of variation, a 75%, 88.9%, and 93.8% Chebyshev interval about the mean, and the five number summary. The average number of sweatshirts owned was 7.
