Two-Variable Statistics Capstone
Two-Variable Statistics Skills
Graph a scatter plot
Estimate the correlation coefficient and describe the relationship
Estimate and find the line of best fit
Interpret the values in the line of best fit equation
Predict values given using the line of best fit
Calculate and understand the residuals
Common Core State Standards Discussed:
S.ID.B.6 Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.
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.
b. Informally assess the fit of a function by plotting and analyzing residuals.
c. Fit a linear function for a scatter plot that suggests a linear association.
S.ID.C.7 Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.
S.ID.C.8 Compute (using technology) and interpret the correlation coefficient of a linear fit.
S.ID.C.9 Distinguish between correlation and causation.
