This section provides extensive details on one method. We will use one effective and tricky method to calculate the p-value for Spearman correlation in Excel. Necessary Steps to Calculate P Value for Spearman Correlation in Excel -1 indicates a perfect negative correlation between two ranksĪ p value is a probability of obtaining the observed difference(or a larger one) in the outcome measures, given that no difference exists between the data containing paired samples.Īssumptions of a Spearman Correlation Test.The Spearman correlation coefficient (r s) can have a value between +1 and -1 Here, is the difference between the ranks in i-th sample. Spearman correlation is often denoted as ρ or r s like the following form. Through this Spearman correlation test, one can calculate the Spearman correlation coefficient(r s) and p value. Spearman correlation test measures the strength and direction of a monotonic association between two ranked variables.
