Does correlation prove that one thing caused another?
No. A correlation only describes how two columns moved in this file. Other variables, timing, missing data, and chance can affect the result.

A useful comparison, not an explanation
Pearson correlation compares how closely two numeric columns follow a straight-line pattern. Rank correlation compares the order of the values, which can be useful when the relationship is consistent but not perfectly linear.
Neither score proves that one variable caused the other. Check the number of included rows, missing values, unusual days, and other factors before deciding whether a pattern deserves more observation.
Common questions
Does Kiomora receive my CSV file?
No. The selected file is read and analyzed inside your browser. This tool does not upload the file or save its contents.
What data works best?
Use a header row and at least three rows where both selected columns contain numbers. More consistent records usually make the comparison easier to interpret.
