First mean is calculated.
Then calculate deviations from the mean.
Then the deviations are squared.
Then the squared deviations are summed up.
Finally this sum is divided by number of items for which the variance is being calculated. For a population, it is by the number of values, in this case 12. If it is a sample, then we divide by one less, which is 11,
For these figures, the variance for the population is 11069.24306. If it is a sample, it is 12075.53788 as the result.

What is the sample variance and the estimated standard error for a sample of n 4 scores with SS 300?
The sample variance is obtained by dividing SS by the degrees of freedom (n-1). In this case, the sample variance is SS/(n-1) = 300/(4-1) = 300/3 = 100 In order to get the standard error, you can do one of two things: a) divide the variance by n and get the square root of the result: square.root (100/4) = square.root(25) = 5, or b) get the standard deviation and divide it by the square root of n. 10/square.root(4) = 10/2 = 5

HOW do you find 40 percent of 25?
You multiply 25 by .40 to get 40% of 25. 25*.40=10
How do you Order from least to greatest 25 23 415?
To order from least to greatest, simply list each number from the smallest size to the biggest size, separating each number by a comma. The sequence would be 23, 25, 415.
How is 25 percent is 10 percentage of 40?
To find 10% of 40, you would multiply 40 by 0.10, which equals 4. To find 25% of 40, you would multiply 40 by 0.25, which equals 10. Therefore, 10 is indeed 25% of 40, as 10 is one-fourth (25%) of 40.
