It is the type of plot on any cartesian coordinate , where various points are plotted in two variables for the set of data , is referred to as a scatter plot.
The data of the particular experiment is plotted as the collection of dots , where it corresponds to two values , one in the horizontal axis and other in the vertical axis .
Hence , from the question ,
Kate can use the method of scatter plot , in order to plot the relation between sleep hours with grade point average.
Scatterplot is a type of representation of data that presents the relationship in between two variables, normally numerical variables. In this plot the data variables are shown on the horizontal, and vertical axis to represent the affect of the variables on one other.
Kate would use the scatterplot as it would provide better visual depiction of the correlation between grade point average and hours of sleep.
