Private on your device

Your information stays on your device and is not uploaded.

Paste numeric lists or paired data to calculate descriptive statistics, fit regressions, and review accessible plot summaries. Probability helpers and CSV export stay on your device for classroom and personal analysis.

The Utilnivo Statistics Calculator helps students and analysts summarize numeric lists and explore simple relationships between two variables. Enter data once, then inspect count, sum, mean, median, mode, range, variance, and standard deviation without sending values to a server.

Paired data supports linear regression with an equation string, correlation coefficient, and R². Residuals and plot summaries stay accessible so screen-reader users can understand the same story the visual charts convey.

Probability helpers for common distributions are available through the shared math engine. Inputs are validated so invalid probabilities and impossible parameters produce clear errors instead of silent NaN results.

All processing is local. You can paste from a spreadsheet, import CSV text, and export cleaned results. This keeps classroom datasets and personal experiments private while still providing the statistics workflows people expect from an advanced calculator suite.

How to use this tool

Enter values separated by commas, spaces, or new lines. Review count, mean, median, and standard deviation. Paste x,y pairs for linear regression. Export a CSV summary when you need a record.

Worked example

For the list 1, 2, 3, 4, 5 the mean is 3, the median is 3, and the sample size is 5. For pairs (1,2), (2,4), (3,6) linear regression recovers a slope near 2.

When to use this

  • Summarizing class or lab measurements quickly.
  • Checking correlation strength for a simple scatter relationship.
  • Preparing a local CSV export of summary results.

Common examples

  • 1, 2, 3, 4, 5
  • mean and median
  • linear regression
  • standard deviation

Common mistakes

  • Including non-numeric text without cleaning the list first.
  • Interpreting correlation as causation.
  • Using too few points for a meaningful regression.

How it works

Paste or type a numeric data list. Utilnivo computes one-variable summaries locally, fits optional regressions to paired data, and prepares accessible plot summaries without uploading your dataset.

Limitations

Results are based on the inputs you provide and may not cover every edge case. This tool is for general use and is not professional advice.

Privacy and file handling

Your data stays on your device and is not uploaded.

Formula or method

Descriptive statistics use standard formulas for mean, median, variance, and quartiles. Linear regression minimizes squared residuals and reports R and R² when defined.

FAQ

Frequently asked questions

What statistics can I calculate from a data list?

Count, sum, mean, median, mode, range, variance, standard deviation, and quartiles are available for valid numeric lists.

Can I run linear regression?

Yes. Paste x,y pairs to fit a line and review the equation, R, and R² when defined.

Is my dataset uploaded?

No. Statistics and regressions are computed locally in your browser.
