Multiply that number by the number of people in your sample minus one. In the formula that is: (N-1)SxSy. 8. Take the number you calculated first [Σ (X-Mx) (Y-My)] and divide it by the number you just got [ (N-1)SxSy]. 9. Interpret your result. r is the symbol used to denote the Pearson Correlation Coefficient).

(Round to three decimal places as needed.) TO A Yes. The correlation between the expected 2-scores and the observed data, exceeds the critical value. Therefore, it is reasonable to conclude that the data come from a normal population O B. No. The correlation between the expected Z-scores and the observed data, does not exceed the critical value.To find the critical value for a correlation coefficient on TI-84, follow these steps: 1. Turn on the diagnostic mode on your TI-84 calculator. To do this, press the [2nd] key, then press the [CATALOG] key (located above the \'0\' key). Scroll down to find the \"DiaGnosticOn\" option and press enter to select it. 2.Here are the steps to take in calculating the correlation coefficient: 1. Determine your data sets. Begin your calculation by determining what your variables will be. Once you know your data sets, you'll be able to plug these values into your equation. Separate these values by x and y variables. 2.
