What does standard deviation measure? What is a standard deviation, and how do you find it? The mean is 71 and the standard deviation is 9. What is the z value of the value 66? If X has a normal distribution with a mean of 10, and a standard deviation of 5 , what is P(X)?
In short, a lower standard deviation means that the elements of the set are clustered more closely around the mean. The standard deviation is particularly useful when working with normally distributed data, but it can be used to make useful inferences about all kinds of statistics. ...

While deviation gives an idea of the distance of each data point from the mean, it does not provide a comprehensive picture of the dataset's overall variability. Standard Deviation builds on the concept of deviation by squaring the differences, averaging them, and then taking the square root, ...
