Hourly Wage ($)
Sketch a scatterplot showing the association between the wage and the years of experience. Describe the association.
Create a scatterplot with the x-axis labeled "Experience (years)" and the y-axis labeled "Hourly Wage ($)."
See CCA 6-85(a) Answer eTool (Desmos). Remember to describe the association.
Sketch the residual plot. Is a linear model appropriate?
Refer to the Math Notes box in this lesson to review residual plots.
See CCA 6-85(b) Residual Answer eTool (Desmos). Is the linear model appropriate?
Why or why not?
What is the correlation coefficient? What does it tell you?
Remember that the correlation coefficient, r, is a measure of how much or how little the data is scattered around the LSRL.
