Computing pairwise correlations...
Sent to — correlation heatmap, ranked relationships with significance, strongest-pair scatter, R code, and AI insights.
Analyze another fileFor every pair of your selected columns, the analysis computes the Pearson correlation coefficient (r) — a -1 to +1 score of how tightly the two move together — plus a significance test of whether that relationship could be chance. The heatmap shows the full matrix, the table ranks the strongest pairs, and the scatter shows the dominant relationship's actual shape.
Use it when you have several numeric columns and want a fast map of what relates to what — before regression, forecasting, or dashboard pruning.
Not for categorical columns (use the categorical association tool) and blind to non-linear patterns — always sanity-check the scatter.
Built for: Analysts and operators exploring relationships in metric data
Typical data source: Any spreadsheet or CSV with several numeric columns
Any table with several numeric columns. For example, weekly business metrics:
Minimum 10 rows · Best with 50-10,000 rows and 3-12 numeric columns
Standard-library analysis: pairwise correlations across the numeric columns you choose. A full correlation heatmap, the strongest relationships ranked with significance tests, and a scatter of the single strongest pair — so you can see which metrics move together, how tightly, and whether it's statistically real. Works on any dataset: map 2 or more numeric columns.
Every pairwise relationship at a glance — blocks of red/blue reveal families of metrics that move together.
The top relationships ranked by strength, each with a significance test so you know what's real.
The strongest relationship plotted point by point, so you can see its actual shape and spot outliers.
Plain-English interpretation — what the numbers mean, what's significant, and what to do next.
Which of my metrics actually move together?
Map your numeric columns. The heatmap shows every pairwise relationship at a glance, and the ranked table tells you which correlations are statistically real versus noise.
