What is tau-squared statistics in random effects meta-analysis for?
It is the estimate of between-study variance, to quantify heterogeneity
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.

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.
How do you estimate the narrow sense heritability based on the halfsib offspring of open pollinated trees?
Narrow sense heritability can be estimated by calculating the resemblance between half-sib offspring raised in a common environment. By measuring the similarity in traits among these offspring and accounting for the relatedness between them and their common parent, one can quantify the proportion of variation in the traits due to additive genetic factors. This provides an estimate of the narrow sense heritability of those traits.
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 much error between sample mean and population mean?
The answer depends on the underlying variance (standard deviation) in the population, the size of the sample and the procedure used to select the sample.
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.
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.
The difference between variance and standard deviation?
The SD is the (positive) square root of the variance.
Is there any difference between sales volume variance and Sales Quantity Variance?
Yes
