Standard deviation is basically used for the variability of data and frequently use to know the volatility of the stock. A mean is basically the average of a set of two or more numbers. Mean is basically the simple average of data. Use. Standard deviation is used to measure the volatility of a stock.

Q. What is mean deviation how is it calculated?
Mean deviation is a statistical measure of the average deviation of values from the mean in a sample. It is calculated first by finding the average of the observations. The difference of each observation from the mean then is determined. The deviations then are averaged.
Q. What is mean deviation and its merits and demerits?
Mean deviation is a measure that removes several shortcomings of other measures i.e. it does not ignore extreme terms or values which play a significant role in average or Mean. According to some Economists, Mean Deviation is very useful for the forecasting of Business Cycles.
Q. Why we use mean deviation?
Mean deviation can give us a sense of how much data is dispersed from one of the average measurements (mean,mode,median). Mean deviation depends on the difference between the data and the average measurement.
Q. Why is standard deviation is important?
Things like heights of people in a particular population tend to roughly follow a normal distribution. Standard deviations are important here because the shape of a normal curve is determined by its mean and standard deviation. The mean tells you where the middle, highest part of the curve should go.
Q. What does average deviation tell you?
Average deviation, combined with mean average, serves to help summarize a set of data. While mean average roughly gives the typical, or middle value, average deviation from the mean gives the typical spread, or variation in the data.
Q. What is a good average deviation?
For an approximate answer, please estimate your coefficient of variation (CV=standard deviation / mean). As a rule of thumb, a CV >= 1 indicates a relatively high variation, while a CV < 1 can be considered low. A “good” SD depends if you expect your distribution to be centered or spread out around the mean.
Q. What does deviation mean?
: an act or instance of deviating: such as. a navigation : deflection of the needle of a compass caused by local magnetic influences (as in a ship) b mathematics : the difference between a value in a frequency distribution and a fixed number (such as the mean)
