      In statistics, the Pearson product-moment correlation coefficient (sometimes referred to as the PMCC, and typically denoted by r) is a measure of the correlation (linear dependence) between two variables X and Y, giving a value between +1 and −1 inclusive. It is widely used in the sciences as a measure of the strength of linear dependence ...

      This number is called “the critical value of r”. Draw your conclusion by comparing the calculated and critical r values: If the absolute value of the correlation coefficient you calculated is above the critical r value from the table, reject your null hypothesis and conclude that there is a statistically significant relationship between the ...

      The reliability between the pre-post tests was determined using the Pearson Correlation. The first in dependent t-test that was run compared the pre-test of the treatment group with the pre-test of the control group. The results were t(22) = 0.47, p > .05. this simply means the obtained value of 0.47 is less than the critical value of 0.63.

      Look at the ‘critical t’ for a one-tailed test in the printout. This is the value given for p = 0.1 in a t-table (because we are testing only for a difference in one direction - above zero - so we can double the normal probability of 0.05). We should have used this value, not the value for p …
