Statistical inference based on Pearson's correlation coefficient often focuses on one of the following two aims: • One aim is to test the null hypothesis that the true correlation coefficient ρ is equal to 0, based on the value of the sample correlation coefficient r.• The other aim is to derive a confidence intervalthat, on repeated sampling, has a given pr…

r, the Pearson product-moment correlation coefficient for a sample of ... Application of this formula to any particular observed sample value of r will ...

It will also output the z score, p-value, and confidence intervals (two-sided bounds and one-sided bounds) for all but the weighted Pearson's coefficient. The output also includes the least-squares regression equation (regression line) of the form y = m · x + b where m is the slope and b is the y-intercept of the regression line.

The final step in the process of calculating the p-value for a Pearson correlation test in Excel is to convert the t-statistic to a p-value. Before this can be done, we just need to calculate a final piece of information: the number of degrees of freedom (DF). The DF can be found by subtracting 2 from n ( n – 2 ).

Pearson Correlation Coefficient Calculator. Pearson's correlation coefficient measures the strength and direction of the relationship between two variables. To begin, you need to add your data to the text boxes below (either one value per line or as a comma delimited list).
