Statistical graph maker
Paste one numerical data series. The tool draws the selected graph and calculates the mean, median, standard deviation and frequency table.
Data graph
The histogram and polygon use the selected number of equal-width bins. The ECDF shows the share of observations less than or equal to x.

How do I use this page?
- Paste your numerical data.
- Choose a histogram, frequency polygon or ECDF.
- Compare the graph with the table and descriptive statistics.
What this page does not do: Up to 5,000 numbers. The graph does not replace data quality checks, missing-data analysis or model selection.

Theory — how does the statistical graph maker work?
A histogram groups numbers into bins and shows how many values fall into each one. A frequency polygon connects the midpoints of those same bins with a line, making it easier to compare the shape of several distributions at once. An ECDF requires no grouping at all — for every value it shows the share of observations that are less than or equal to it. Changing the number of histogram bins can noticeably change its appearance, so it is worth checking a few variants before drawing conclusions.
