Significance of coefficient of correlation
WebIf the p-value for a variable is less than your significance level, your sample data provide enough evidence to reject the null hypothesis for the entire population.Your data favor the hypothesis that there is a non-zero … WebThere are tests of statistical significance that can be applied to individual correlations, which indicate the probability of obtaining a correlation as large or larger than the the sample correlation assuming the null hypothesis is true. The key point is that what constitutes a statistically significant correlation coefficient depends on:
