Find a data set and take a sample of 15 - 20 observations (the data set cannot be in the book). Your first post should be your data set along with a description of what it is, where it comes from, and how you chose your sample data.Your first response to a post is to find the mean, median and mode for that data set. Your second response is to a different post and you need to find the standard deviation for that data set. Each data set should end up having a post with: 1. the data set and description, 2. the mean, median, and mode for the data set, and 3. the standard deviation for the data set. Remember you are working with sample data here so be sure to use the correct formulas.
