What is the standard deviation of the data set? 7,3,4, 2, 5, 6,9

2.4103

Step-by-step explanation:

The first step in evaluating the sample standard deviation of a data set involves the determination of the sample mean.

The sample mean is simply the average value of the data set;

sample mean =

The next step is to evaluate the sum of the squares of deviations from the mean;

sum of squares of deviation =

We then divide the sum of squares of deviation by (n-1) where n is the sample size to obtain the sample variance;

variance =

The standard deviation is simply the square-root of variance;

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

it alot will look like this 4.4

it is only things thain can be deafeated
