Types of Relationships in Scatter Plots | 8.SP.A.1💗

In this video lesson we will learn about the types of relationships in Scatter Plots. We will begin by understanding a scatterplot is a graph of bivariate data. Two questions have been asked and answered to form ordered pairs. The data is graphed on a coordinate plane to determine if a relationship exists between the two variables. We will identify positive linear relationships, negative linear relationships, no relationship, and nonlinear relationships. We will briefly discuss nonlinear relationships - exponential, quadratic and cubic. We will also learn how to identify an outlier, a cluster and gaps in the data of a scatter plot. Student practice is embedded in the lesson. Modeled exemplar solutions are provided for each of the practice problems.
