Suppose we would like to find a characteristic of the relationship between the number of hours spent mowing and how much water a person consumes based on the data set from a seven-days experiment. Data of mowing time and water consumed are listed in column 1 and 2 of the table below, respectively. Notice that pair values of X and Y variable have already been rearranged in an ascending order based upon X observations.
