The closer a data points residual is to 0, the better the fit. In our example, these numbers represent measurements of You can find the standard deviation of a data set in two ways with your TI-84 Graphing Calculator. For example, if the height of student is 1.36, its predicted weight is 53.08, if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[336,280],'reneshbedre_com-large-leaderboard-2','ezslot_4',147,'0','0'])};__ez_fad_position('div-gpt-ad-reneshbedre_com-large-leaderboard-2-0'); = -22.37 + (55.48 * 1.36) = 53.08. This plot visually shows the difference between the y-value of each data point and the corresponding y-value associated with the regression equation. Both are available in the test output of R. Of course whether a difference is large is hard to tell from absolute counts, but it will give you some sense where the differences are.
