Which correlation method should I choose?

Use Pearson for linear relationships between continuous variables, Spearman for monotonic relationships, and Kendall for smaller datasets or when data contains many tied ranks.

How does the tool handle missing data?

You can choose to remove rows with missing values, or fill them using the column mean, median, or linear interpolation.

What is the purpose of the p-value?

The p-value indicates the statistical significance of the correlation; a lower p-value generally suggests that the observed relationship is unlikely to have occurred by chance.

Can I analyze data by specific categories?

Yes, use the 'Group Column' feature to segment your analysis by categories like region, department, or time period.

What is the difference between Pearson and Spearman?

Pearson measures the strength of a linear relationship, while Spearman measures the strength of a monotonic relationship based on the rank of the data.
