❓ FAQ
What is the difference between mean and median?+
The mean (average) is the sum of all values divided by the count. The median is the middle value when sorted. The median is more robust to outliers — if Bill Gates walks into a room, the mean wealth skyrockets but the median barely changes.
What is standard deviation?+
Standard deviation measures how spread out the values are from the mean. A low SD means values are clustered close to the mean; a high SD means they are spread out. SD = square root of the variance.
What is the mode?+
The mode is the most frequently occurring value. A dataset can have no mode (all values unique), one mode, or multiple modes (bimodal, multimodal). This tool shows all modes if there are multiple.
What is variance?+
Variance is the average of the squared differences from the mean. It measures the spread of the data. Standard deviation = √Variance. Variance is in squared units, so standard deviation (same units as data) is often more interpretable.
When should I use median instead of mean?+
Use median when your data has significant outliers or is skewed (e.g. income data, house prices). Use mean when data is normally distributed without extreme outliers.
