Given an experimental situation, the student will write linear functions that provide a reasonable fit to data to estimate the solutions and make predictions.

Use this lesson, practice exercise, and teacher resource in planning instruction on scatter plots and line of best fit. In the lessons, you'll find definitions and examples of ways to make a scatter plot, determine correlations, and find...

A line plot may not be a useful graph for investigating variation so we must come up with a new representation based on groups of data. Construct a stem and leaf plot from a set of 26 data values.
