\2 $E[XY]$ is expected value of $X * Y$
\2 Linearity of expectation
\1 Mean, median, mode
\2 \textit{When to use each}
\2 Categorical: mode, total: mean, skewed: median, else: mean
\2 Additive (arithmetic), multiplicative (geometric), harmonic
\2 Mistakes with means: large range, skewness, multiplying when not
independent, ratio with different bases
\1 Covariance
\2 Measure whether two random variables vary together
