Now let's delve into sample variance. The definition is similar to that of population variance, but the formula differs.

Formula

Sample Variance

Look at the example of variance rounded to two decimal points for the column 'salary_in_usd':

salaries_distribution

The variance of the column 'salary_in_usd' is 5034932663.18

Variance Key Note

We can see that the variance of the 'salary_in_usd' column is quite substantial. The values in this column are spread out a lot.

Note

The greater the variance, the more the values are scattered.

Select the one with lower variance from the graphs with an equal number of observations and identical mean values.
