`SD = sqrt(Σ (x - mean)`^{2} / n)

`If you need to calculate the standard deviation of a set of data, a useful formula to use is ``SD = sqrt(Σ (x - mean)`^{2} / n)

. To get started, you'll need to first calculate the mean of your data. Once you have the mean, you can calculate the squared differences between each data point and the mean. After you've added up the squared differences, you can use the formula above to calculate the standard deviation.
For more information on calculating standard deviation, you can reference helpful tutorials online, or find helpful functions in programs like Sourcetable.

`The formula for standard deviation is ``SD=âˆ‘âˆ£xâˆ’xË‰âˆ£2n`

.

Standard deviation is used to measure the spread of a data set, or how far apart the data points are from each other and from the mean.

`SD = sqrt(Σ (x - mean)`^{2} / n)

Standard deviation is a statistic used in finance to measure how dispersed a dataset is. It is calculated as the square root of the variance by determining the deviation of each data point from the average.

Stable blue-chip stocks generally have a low standard deviation, as their prices tend to remain stable over time.
