Distribution
You've probably heard of mean, median, and mode. Schools teach you this
stuff in high school; although they should teach it much sooner. The mean
is the sum of all data points divided by the number of points. To find the
median, you order your data from least to greatest and mark the halfway
point. The mode is the number that occurs the most. These are well and
good and super easy to find, but they don't give you the whole story. They
describe how parts of your data are distributed. If you visualize everything
though, you can see the full distribution.
