![]() The procedures in the calculator in alphabetical order. The TI 83/84 Calculator to Find Equations of Regression Lines and CoefficientsĬoefficients of determination and correlation, you must first make a change in Similar to those shown in the figure below. Once you make that decision, your axes should be fairly You would pick the first row or column as your x-values and the second row or column as your y-values. ![]() Once the axes are set up, you just act like each pair of x- and y-values is an ordered pair, and you plot these ordered pairs onĬonsider Table 1 on page 178 of Sullivan, which is reproduced below. Number line on your horizontal axis so that the values extend from the minimum x-value to the maximum x-value but not much farther.Īnd set up a uniform number line on the vertical axis so that the values extendįrom the minimum y-value to the maximum y-value Outliers and Influential Observations inĭiagram is a fairly straightforward process.
