The ability to quickly match empirical data to well-known mathematical models is an essential feature in the analysis of experiments. This technique is generally referred to as curve-fitting. The up-and-coming, but not yet leased, CloudLab software from PocketLab provides an easy way to fit data to models including linear, quadratic, power, exponential, and logarithmic. This curve-fitting can be done for any selected region of PocketLab data. This lesson provides a sneak preview of this CloudLab feature, allowing students to study the inverse square law of light.
