Which Model Models Best?

Why might a logarithmic function be the best fit for the data? 

The data increases, but once a girl reaches the late teen years, the height starts to “level off” when she reaches her adult height.  This and the shape of the data in the scatter plot indicate that a logarithmic function may be the best fit.

Check Your Understanding

Test and Confirm

  • Graph the logarithmic curve of best fit on the scatter plot.
  • Calculate and review the residual plot to determine if the model is the best fit. Explain your reasoning.
