  • 8.SP.J Investigate patterns of association in bivariate data.

    • 8.SP.J.1 Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Describe the association by form (linear/nonlinear), direction (positive/negative), strength (correlation), and unusual features.

    • 8.SP.J.2 Know that straight lines are widely used to model relationships between two quantitative variables. For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.

    • 8.SP.J.3 Use an equation of a linear model to solve problems in the context of bivariate measurement data, interpreting the slope and intercept.

    • 8.SP.J.4 Understand that patterns of association can also be seen in bivariate categorical data by displaying frequencies and relative frequencies in a two-way table.

      • 8.SP.J.4A Construct and interpret a two-way table summarizing data on two categorical variables collected from the same subjects.

      • 8.SP.J.4B Use relative frequencies calculated for rows or columns to describe possible association between the two variables.
