Unit Overview: Scatter Plots and Data
We are now starting the chapter that covers scatter plots. Scatter plots compare two sets of numeric data
using a dot or box plots by comparing shape, center, and spread. The data is used from a random sample
to make inferences about a population or to make predictions.
