What is a scatter plot?
A scatter plot places each observation at the intersection of two numeric values. The overall pattern can reveal positive or negative association, clusters, gaps, and unusual observations that deserve investigation.
How to make a scatter plot
- Arrange paired numeric values in your spreadsheet.
- Upload the file or enter the observations manually.
- Use a title that names both measurements and include units in the column headers.
- Inspect the pattern and export the plot as PNG or SVG.
Interpret with care
A tight upward pattern suggests positive correlation; a downward pattern suggests negative correlation. A diffuse cloud suggests weak or no linear association. Always investigate outliers and remember that correlation is not evidence of causation.
Frequently asked questions
What data do I need for a scatter plot?
You need paired numeric observations: one value for the horizontal axis and one corresponding value for the vertical axis.
Does a scatter plot prove causation?
No. A visible association can suggest a relationship, but it does not by itself establish that one variable causes the other.
Can I download the result?
Yes. Export the scatter plot as a high-resolution PNG or scalable SVG.
