Pressing 6actually enters two variables into the statistics registers because the value already in the Y–register is accumulated as the y–value. For this reason, the calculator will perform linear regression and show you values based on y even when you have entered only x–data — or even if you have entered an unequal number of x–and y–values. No error occurs, but the results are obviously not meaningful.
