How do i know if a correlation is significant
WebThe value of correlation is limited between -1 and +1 and can be interpreted as follows: -1: If it is -1, then variables are known as perfectly negatively correlated. That means if one variable is moving in one direction, another is moving in the opposite direction. 0: That means the variable is not having any correlation. WebThe formula for the test statistic is. t = r n − 2 1 − r 2. t = r n − 2 1 − r 2. The value of the test statistic, t, is shown in the computer or calculator output along with the p -value. The test statistic t has the same sign as the correlation coefficient r. The p -value is the combined area in both tails.
