Find out what a scatter plot is and how it can be used to investigate relationships between two variables. Gather and analyse data for a pair of variables such as hand span and foot length. Enter your data set and plot it on a graph. Use a line of best fit to identify if there is a positive or negative relationship between the two variables. This learning object is one in a series of five objects.
