The Pearson Correlation Measures Quizlet. Basically a Pearson product-moment correlation attempts to draw a line of best fit through the data of two variables and the Pearson correlation coefficient r indicates how far away all. Pearson correlation coefficient formula.
Σy the sum of y scores. First we will calculate the following values. Σx the sum of x scores.
As Figure 64 shows Pearsons r ranges from 100 the strongest possible negative relationship to 100 the strongest possible positive relationship.
First we will calculate the following values. A The correlation r is equal to 20 10 400 10 10 10 40 10 X SS Y SP r 6. Measures the amount of covariability between the two variables SP sum X-MxY-My Mx. Use of the term correlation coefficient is almost always a short-hand phrase for the Pearson product-moment correlation coefficient.
