Calculate coefficients instantly with the Correlation Calculator by Ease Tools. Analyze Pearson correlation for accurate statistics and data insights.

Love how clean the interface is, no clutter just the two variables and the result. Nice that it does Pearson by default and doesn't bury the formula explanation behind extra clicks.
Ran a quick check on two columns of sales data and got the Pearson result in seconds without having to open a spreadsheet. Simple and does exactly what it says.
Would be great if you could add Spearman and Kendall correlation options too since Pearson only works for linear relationships and a lot of datasets I work with are non-linear or have outliers.
The instant Pearson calculations are exactly what I needed for quick data checks without firing up a full stats program. Clean, no-fluff interface that just works.
