# Sample Variance

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

**Formula**

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

:

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.
