  • Investigate patterns of association in bivariate data.

    • NC.8.SP.1 Construct and interpret scatter plots for bivariate measurement data to investigate patterns of association between two quantities. Investigate and describe patterns such as clustering, outliers, positive or negative association, linear association, and nonlinear association.

    • NC.8.SP.2 Model the relationship between bivariate quantitative data to:

    • NC.8.SP.3 Use the equation of a linear model to solve problems in the context of bivariate quantitative data, interpreting the slope and y-intercept.

    • NC.8.SP.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.

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

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