Spectrum Math Grade 8 Chapter 6 Lesson 6.2 Constructing Scatter Plots Answers Key
A scatter plot is a way of displaying bivariate data, or two sets of data. A scatter plot can show the relationship between the bivariate data. Scatter plots can show if the values increase or decrease relative to each other and if there are any outliers in the data.
Step 1: Set up the x-axis of a graph with intervals for one set of the data and the y-axis for the other set.
Step 2: Use the data sets as ordered pairs to create points on the scatter plot.
Use the data sets below to create scatter plots.
