Summarize, represent, and interpret data on two categorical and quantitative variables
Grade 912
S.ID.5.
Summarize categorical data for two categories in twoway frequency tables. Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). Recognize possible associations and trends in the data.
S.ID.6.
Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.
S.ID.6.a.
Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models.
S.ID.6.b.
Informally assess the fit of a function by plotting and analyzing residuals.
S.ID.6.c.
Fit a linear function for a scatter plot that suggests a linear association.
