Raw data is organized into a frequency table. Why would the raw data to differ from the mean of the frequency table? 13. we expect the mean of 14. mode, but different standard deviations Create two data sets, each with n = 5, that have the same mean, median, and 15. Construct a data set for which N = 7, u = 9, a = 0 16. Graphical Reasoning Both data sets shown in the stem-and-leaf plots have a mean of 165.
