It was not practical for Kerin to measure her classmates’ feet, so Kerin collected the following shoe-size data from some of her classmates. Make a graph with appropriately scaled axes.
What are the largest and smallest values? Consider shoe size and height independently.
Does it matter which data is on the
-axis and which is on the -axis?
Is there a relationship between shoe size and height?
Examine the scatterplot you made in part (a). Estimate a line of best fit to help you see any trends.
Input the data into the eTool below to graph the results.
