Suppose you have n observations {x1, x2, ... , xn} for a variable, X.
Calculate m = (x1 + x2 + , ... , + xn)/n, the mean value.
Calculate s2 = (x12 + x22 + , ... , + xn2)/n
Then Variance = s2 - m2 = [mean of the squares] - [square of the mean]
and the standard deviation = sqrt(Variance)
What else can I help you with?
How do you calculate variance given standard deviation?
Square the standard deviation and you will have the variance.
What is the standard deviation of 9?
You need more than one number to calculate a standard deviation, so 9 does not have a standard deviation.
How do you calculate standard deviation if I know variance?
Standard deviation = square root of variance.
What is the definition of standard deviation?
Standard deviation is how much a group deviates from the whole. In order to calculate standard deviation, you must know the mean.
How do you calculate mean and Median smaller then Standard deviation?
In the same way that you calculate mean and median that are greater than the standard deviation!
Why we calculate standard deviation and quartile deviation?
we calculate standard deviation to find the avg of the difference of all values from mean.,
How do you calculate variance given standard deviation?
Square the standard deviation and you will have the variance.

In the same way that you calculate mean and median that are greater than the standard deviation!
How do you calculate standard deviation using median?
You cannot because the standard deviation is not related to the median.
How do you calculate standard deviation with the help of z-score?
A z-score cannot help calculate standard deviation. In fact the very point of z-scores is to remove any contribution from the mean or standard deviation.
What is the minimum data required for standard deviation?
The standard deviation is a measure of how spread out the numbers are. Three points is needed to calculate a statistically valid meaningful standard deviation.
How can I calculate the standard deviation of a portfolio in Excel?
To calculate the standard deviation of a portfolio in Excel, you can use the STDEV.P function. This function calculates the standard deviation based on the entire population of data points in your portfolio. Simply input the range of values representing the returns of your portfolio into the function to get the standard deviation.
How do you calculate standard deviation on CASIO fx-82tl?
NO
How do you calculate the standard deviation of the mean using Excel?
=stdev(...) will return the N-1 weighted sample standard deviation. =stdevp(...) will return the N weighted population standard deviation.
