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 factors causes Budget Variance?
There are 7 variances associated with a budget ( which are generally calculated for controlling purposes) 1- Material Price variance 2- Material Quantity variance 3- Labor rate variance 4- Labor efficiency variance 5- Spending variance 6- Efficiency variance 7- Capacity variance
What is Assumptions for Variance Homogeneous?
Equal in 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 sample variance of 5781010 and 14?

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 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 are the variances in a 4 variance analysis?

What factors causes Budget Variance?
There are 7 variances associated with a budget ( which are generally calculated for controlling purposes) 1- Material Price variance 2- Material Quantity variance 3- Labor rate variance 4- Labor efficiency variance 5- Spending variance 6- Efficiency variance 7- Capacity variance
Which is not a measure of dispersion range or variance?

What is the significance of food service?

What is a food service area?
A food service area is an area where food is served.
How do you calculate Total revenue variance?
total revenue variance = actual revenue - standard revenue Total revenue variance (AQ x AP) - (SQ x SP) where AQ is actual quantity (units of service sold), AP is actual price (actually recorded as revenue), SQ is standard quantity, and SP is standard price
Can variance be negative?
Since Variance is the average of the squared distanced from the mean, Variance must be a non negative number.
What is Proportion of variance unaccounted?
The unaccounted for variance aka Error Variance, is the amount of variance of the dependent variable (DV) that is not accounted for by the main effects/independent variables (IV) and their interactions.
