mean:

median:

mode:

range:

standard deviation:

unimodal:
bimodal:

mean: average (add all #’s, divide by #

median: middle number

mode: occurs most often

range: max - min

standard deviation: how data varies from mean (high: spread out; low: close to mean)

unimodal: one peak
bimodal: two peaks

correlation:

direct variation

inverse variation:

correlation: if both variables increase

direct variation: 2 quantities have direct relationship

inverse variation: one increases, other decreases
