Statistics lab
Paste a number list for mean, median, mode, and quartiles; paste coordinate pairs for a quick scatter plot and least-squares line; run fair coin or die trials for probability intuition. Built for middle school data work, no account required.
List summary
Paste numbers separated by commas, spaces, or line breaks. We compute mean, median, mode (when repeats exist), and quartiles for a quick class check.

- Median

- Mode
- — (no repeat)
- Q1 / Q3
- 12.0000 / 16.0000
- IQR

Scatter from pairs
One pair per line as x, y (comma or tab). Points scale to fit; the blue segment is the least-squares line when the x-values are not all identical.
- Points
- 5
- Mean x / mean y
- 3.0000 / 4.4000
- Least-squares line
- y = 1.3000x + 0.5000
Fair coin or die
Quick physical-model simulator: each press is an independent trial (50–50 coin or uniform 1–6 die).

About the statistics lab
The statistics lab takes a list of numbers and computes the measures you meet in middle and high school statistics, mean (average), median, mode, range, variance, and standard deviation, and visualizes the data so the shape of the set is easy to read.
Enter or paste your values, and StudyQuest shows each result with the steps behind it. Use it to check homework, explore how outliers move the mean and median, and build intuition for spread and center.
