Pearson r. There is a simple and straightforward way to measure correlation between two variables. It is called the Pearson correlation coefficient (r) – named after Karl Pearson who invented it. It's longer name, the Pearson product-moment correlation, is sometimes used. The formula for computing the Pearson r is as follows:

For each scored column, calculate the Pearson correlation by creating two unique data arrays. [Excel syntax: CORREL (array1, array2)] Create the first data array by selecting all column values (Array 1) and the second array by selecting all column values (Array 2) for the overall raw score. .

Understanding the Pearson Correlation Coefficient (r) The Pearson product-moment correlation coefficient (r) assesses the degree that quantitative variables are linearly related in a sample. Each individual or case must have scores on two quantitative variables (i.e., continuous variables measured on the interval or ratio scales).

So, she must now plug this Pearson Correlation value (.65) into the Spearman Brown Split-Half “correction” Formula to estimate the reliability of the whole test. rsb = 2rxy /(1+rxy) where rxy is the old Pearson reliability coefficient. where rsb is the new Spearman Brown correction reliability coefficient. rsb = 2 x .65 / 1 + .65 = rsb = 1 ...
