Answer:
10.94
Step-by-step explanation:
The standard deviation is calculated by using the following formula:
This means that N is the total number of cases you want to take into account, times the sum of x at the ith position - x squared.
In other words, the standard deviation in your example implies the following:
26 is the first value, so i = 1, 34 is the second value, so i = 2, 18 where i = 3, and so on and so forth, until you reach the end, which is 6 (so the initial value is 1 and the last one is 6).
You're doing a sum over an iteration of all the numbers in your sample.
So applying the sum of all of the numbers, it gives us the following:
The sum of all of the numbers in your sample is equal to 119.6.
Substitute into the equation once again:
Where the square root of 119.6 is 10.93617...
Rounded to two decimal places: 10.94
