For example, a quality analyst tests whether the variance of fill volumes is different from the target of 2.5.
If the variance of a set of numbers is 9, then the standard deviation is 3.
The variance of the conversion rate can be estimated directly using a mathematical model but the variance of revenue per order is specific to the campaign.
Because the variance is not in the same units as the data, the variance is often displayed with its square root, the standard deviation.
The variance V is designed to allow gateways to use parallel paths of different speeds.
In our example, the variance was 200, therefore standard deviation is 14.14.
Then we do a F-test to know if the variance are equal.
Commodity futures are bought almost entirely on margin, so the variance is much higher.
A Student't test and a Fisher's test are computed to compare the mean and the variance of two samples.
The variance allowed between when the event was sent and when it was received, in seconds. Default: 600.
MOS then uses multi-linear regression equations to remove bias and adjust the variance of the raw model output.
This demonstrates that the linear equation 1.5229* x -2.1911 predicts 87% of the variance in the variable y.
Because the first two components explain as much of the variance in the data as is possible with two dimensions, the plane is the best 2-D linear approximation to the data.
For large n, the empirical variance of the codebook will be very close to the variance of its distribution, thereby avoiding violation of the power constraint probabilistically.
When the variables are in different units or the difference in the variance of different columns is substantial(as in this case), scaling of the data or use of weights is often preferable.
I have never seen it written this way but it gives me a little intuition that sigma squared, it's always written as sigma squared, but it's really just the variance and the variance is what you calculate before you calculate the standard deviation, so that's interesting.
