Find one quantitative and one qualitative data set from a reliable source and determine the best way to present that data graphically. Show your graph and explain your reasoning for choosing this presentation method. When might the reported median of data be more appropriate than the mean of data? What is the purpose of finding the mode of data? Provide an example of when the mode is more appropriate than the mean or median of the data.

Mean is more influenced by deviant scores, so skewed distributions would be better represented by the median.
Mode (most frequently occurring score) would be better, if the distribution is bimodal. A bimodal distribution can usually be separated into two underlying distributions. Handgrip strength would be an example, with men averaging greater handgrip strength than women.
You will need to find your own data sets.
