Lesson 4 Summary

 

This graphic shows a sinusoidal curve of best fit.

 

Curve fitting is the general method for using a line or curve to estimate the relationship between two variables. Throughout Lesson 4 you used a curve of best fit for sinusoidal data, which is periodic and looks like a sine wave when graphed. The curve determines the specific parameters that make the sinusoidal function match your data as closely as possible. After finding the sinusoidal regression function, interpolation and extrapolation can be used. However, care must be taken to make sure the predictions are reasonable.
