Understand the basics of population, data collection, and sampling.

Learn different ways to measure the "center," or typical values, of a set of data: mean, median, and mode.

Learn the concept of dispersion, range, IQR, outliers, and box and whisker plots.

Learn about standard deviation and variance, which we use to measure how tightly or loosely clustered the data is around the mean.

In this lesson, we learn about different ways to visualize data.

Regressions of y on x, regressions of x on y, the correlation coefficient r, the rank correlation coefficient rs​, extrapolation and interpolation of data.
