It is the estimate of between-study variance, to quantify heterogeneity
Favourable variance is that variance which is good for business while unfavourable variance is bad for business
A budget "variance" is the difference between planned and actual performance.
The SD is the (positive) square root of the variance.
Homogeneity means that the statistical properties of the variable which is being studied remain the same across the population. Heterogeneity means that they do not: it could be that the mean changes between different subsets of the population or the variance does.

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.
Negative price variance is when the cost is less than budgeted. Volume variance is a variance in the volume produce.
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.
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.
A budget "variance" is the difference between planned and actual performance.

Standard deviation is the square root of the variance.
) Distinguish clearly between analysis of variance and analysis of covariance.
