# Variance & Std. Deviation
|
|
|
|
Variance measures the average squared deviation from the mean, and standard deviation is its square root in the original units. Both quantify how spread out data values are. Pandas computes them with `var()` and `std()`. A high standard deviation relative to the mean signals high variability in the data.
