Suppose the variance is 64 Find the standard deviation?
Standard deviation is the square root of the variance; so if the variance is 64, the std dev is 8.

How do you calculate a budget variance as a percentage?
actual budget/budget = variance%
Set of 25 numbers has standard deviation 6 then it's variance is?
Square the standard deviation to obtain the variance. The variance is 62 or 36.
How do you compute market price variance?
Price Variance = (Actual Price/Unit - Budgeted Price/Unit) x Actual Quantity of Output = (AP - SP) x AQ

Find the variance of these numbers 77 93 96 96 99?
The variance is: 76.7
Is variance the square root of standard deviation?
No, you have it backwards, the standard deviation is the square root of the variance, so the variance is the standard deviation squared. Usually you find the variance first, as it is the average sum of squares of the distribution, and then find the standard deviation by squaring it.
Suppose the variance is 64 Find the standard deviation?
Standard deviation is the square root of the variance; so if the variance is 64, the std dev is 8.
What is cost price variances?
Price variance is the actual unit cost minus the standard unit cost, multiplied by the actual quantity purchased. The variance is said to be unfavorable if the actual price of the materials is higher than the standard price of the materials.
How do you find range when all you have is the variance?
You cannot.
How do you do variance?
you have to first find the Mean then subtract each of the results from the mean and then square them. then you divide by the total amount of results and that gives you the variance. If you square root the variance you will get the standard deviation
How do you work out variance?

What is difference between the amount budgeted and the actual amount is called?
Difference between actual amount and budgeted amount is called "Variance" and variance analysis is done to find out the reasons for variance
