Find the best fitting line and r2 for replicate 1 with and without the fourth point. Graph the two regression lines and the data.
Consider the following data which include one outlying point. Find the best fitting line with and without that point. How much difference does that point make? The idea of removing one point and testing how much the fit changes is an important tool in regression, and is sometimes called the leverage of that point.
