The mistake he made is that he Yuri divided by n instead of n -1.
<h3>What mistake did he make?

Standard deviation is used to determine how the values in a group differs from the mean of the values in the group.
In order to determine the standard deviation, take the following steps:
• Determine the mean of the observation: 14
Determine the difference between each value and the mean and then square the result: (12 - 14)² + (14 - 14)² + (9 - 14)² + (21 - 14)² = 78
Determine the mean of the sum of the squared differences and then find the square root of the mean: √78/(n - 1) = 5.1

Answer:
It does = 20 you're correct :)
Step-by-step explanation:
No real way to solve it, with the knoledge of the perfect squares (1,4,9,16,25,49 ect) you can do the simple ones but more complicated ones require a calculator to solve it in decimal form
