the mean, while a low variance means the numbers are closer to
the mean. Data Points

Variance
Standard deviation is the square root of the variance, and it
provides a measure of how spread out the values are in the original units (not squared units, like variance). It gives
a sense of how “far” the data points are from the mean on average.
Outlier
An outlier is a data point that is significantly different from the other points in the dataset. It’s an “exceptional”
value that is much higher or lower than most of the other values.
