Deviation The amount by which a single measurement differs from a fixed value such as the mean A significant deviation from the average value Difference An instance of disparity or unlikeness There is a big difference in sound between a clarinet and an oboe. Deviation The deflection of a ship...
I'll be honest. Standard deviation is a more difficult concept than the others we've covered. And unless you are writing for a specialized, professional audience, you'll probably never use the words "standard deviation" in a story. But that doesn't mean you should ignore this concept. Th...

Standard deviation is the spread of a group of numbers from the mean. The variance measures the average degree to which each point differs from the mean. While standard deviation is the square root of the variance, variance is the average of the squared difference of each data point from th...
Definition:Standard Deviation (SD) is a statistical measure that captures the difference between the average and the outliers in a set of data. In other words, standard deviation measures how volatile a set of data is. What Does Standard Deviation Mean?

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. ...
The division by one less than the sample size provides a sort of mean deviation. This negates the effect of having many data points each contribute to the measurement of spread. As stated before, the standard deviation is simply calculated by finding the square root of this result, which pro...
