How It Works
- 1.Mean vs Median: The mean (average) is sensitive to extreme values. The median is the middle value and is more robust. If your data is skewed, the median gives a better picture of the "typical" value. For example, average income is misleading because billionaires pull it up — median income is more useful.
- 2.What Standard Deviation tells you: Standard deviation measures how spread out your data is. A small std dev means most values are close to the mean. A large std dev means wide variation. In a bell curve, about 68% of data falls within 1 std dev of the mean, and 95% within 2 std devs.
- 3.How to spot outliers: The IQR (Interquartile Range) method flags values below Q1 - 1.5*IQR or above Q3 + 1.5*IQR. These are not necessarily errors — they could be legitimately extreme values. Always investigate outliers rather than automatically removing them.
- 4.Reading a histogram: A histogram shows how often values fall into specific ranges (bins). A bell shape means normally distributed data. Two peaks (bimodal) might mean you have two distinct groups mixed together.
- 5.All computation is local: Your data never leaves your browser. Everything is calculated in real-time on your device — no server calls, no data stored.
About This Tool

Why Use This?
Raw numbers are hard to interpret. A table of 100 values tells you almost nothing at a glance, but a histogram or box plot reveals the whole story instantly. This tool bridges the gap between data and understanding.
