What difference between a favorable variance and an unfavorable variance?
Favourable variance is that variance which is good for business while unfavourable variance is bad for business
What is budget variance?
A budget "variance" is the difference between planned and actual performance.
The difference between variance and standard deviation?
The SD is the (positive) square root of the variance.
What is a difference between a pooled variance and a combined variance?
Pooled variance is a method for estimating variance given several different samples taken in different circumstances where the mean may vary between samples but the true variance (equivalently, precision) is assumed to remain the same. A combined variance is a method for estimating variance from several samples, given the size, mean and standard deviation of each. Mathematically, a combined variance is equal to the calculated variance of the set of the data from all samples. See links.
When the null hypothesis is true the ratio of the between groups population variance estimate to the within groups population variance estimate should be about?

What is the difference between negative price variance and volume variance?
Negative price variance is when the cost is less than budgeted. Volume variance is a variance in the volume produce.
What is the difference between analysis of variance and analysis of covariance?
ANOVA characterises between group variations, exclusively to treatment. In contrast, ANCOVA divides between group variations to treatment and covariate. ANOVA exhibits within group variations, particularly to individual differences.
What is the difference between variable overheads cost variance andfixed overheads cost variance?
Variable overhead cost variance is that variance which is in variable overheads costs between the standard cost and the actual variable cost WHILE fixed overheads cost variance is variance between standard fixed overhead cost and actual fixed overhead cost.
How do you figure the variance on a group of numbers?
To figure the variance on a group of numbers, you must first figure out the mean, which is the average of the set. Then, substract the mean from each number in the set. Square the result of those substractions, and then average the squares. You will then have the variance.
What is a budget variance?
A budget "variance" is the difference between planned and actual performance.
What is budget variance?
A budget "variance" is the difference between planned and actual performance.
Is the variance of a group of scores the same as the squared standard deviation?
The standard deviation is defined as the square root of the variance, so the variance is the same as the squared standard deviation.
What is the relationship between standard deviation and variance?
Standard deviation is the square root of the variance.
Distinguish between analysis of variance and analysis of covariance?
) Distinguish clearly between analysis of variance and analysis of covariance.
Is there any difference between sales volume variance and Sales Quantity Variance?
Yes
The difference between variance and standard deviation?
The SD is the (positive) square root of the variance.
