correlation

ignore sign, whichever is closest to 1.0

using s to interpret mean

whichever has smaller standard deviation

descriptive

to describe (procedures used to summarize, organize, and simplify large datasets, making them easier to interpret)

inferential stats

infers something about population (draw conclusions about a large population based on data collected from a smaller, representative sample)

skewed distribution (+)

outliers = high (right side)

mode median mean (L to R)

skewed distribution (-)

outlier = high (left side)

mean median mode ( L to R)

deviation - why n-1?

samples are less variable than population
