Descriptive statistics

Mean (average), median (middle value), mode (most common), range (max − min), variance (spread), and standard deviation (average distance from mean). These six measures describe the centre, spread and shape of any dataset.

Variance vs standard deviation

Variance is the average of squared differences from the mean. Standard deviation is the square root of variance — it's in the same units as your data, making it easier to interpret. A low standard deviation means data is clustered around the mean; a high one means it's spread out.
