The sample standard deviation is used to calculate the determine the spread of estimates for a set of observations (i.e., a data set) from the mean (average or expected value).
<h3>What is sample standard deviation?</h3>
The spread of a data distribution is measured by standard deviation. The average distance between each data point and the mean is measured.
The sample standard deviation (s) is a measurement of the variation from the expected values and is equal to the sample variance's square root.
where
s = sample standard deviation
N = the number of observations
= the observed values of a sample item
= the mean value of the observations

In the initial number xx7,xxx; 7 is in the thousands place meaning its value is 7,000.
If it is moved to the tens place = xxx,x7x then it's value will decrease, it will become 70 only.
Every placement has its corresponding values, thus whereven the number 7 is place it is multiplied by its corresponding values (ones, tens, hundreds, etc).
