Variances are calculated for various reasons. Here is an example of why:
A geologist wants to know where the North American Plate is moving. He measures the position one year. When he re-measures on the same spot he did the previous year, he finds that the new data is 1 inch west of his original measurment. Therefore, he now knows the North American plate is moving west at a rate of 1 inch per year.

What does activity-level variances plus flexible-budget variances equal?
total master-budget variances
What are adverse variances?
Adverse variances means unfavourable variance which is actual expenses are more than budgted variance.
Why are variances generally segregated in terms of a price variance and an efficiency variance?
Efficiency Varian materials and direct labor, the variances were recorded in specific general ledger accounts.
What does the F statistics tell you?
The difference between two variances
What are budget variances?
Budget variances are differences in expenditures from your original budgeted plan. This may happen if there is an expense during the month that one may not have planned for such as an automotive repair or doctor's bill.
What does activity-level variances plus flexible-budget variances equal?
total master-budget variances
The variances that should be investigated by management include?
should all variances be investigated
What is the F stat in regression analysis?
The F stat tests the equality of variances. It uses statistical tables for reference and is calculated with F = Variance 1 (max)/variance 2(min).
When comparing two variances or standard deviations is an f-test is used?
An F-test can be used for variances.
What has the author Sharon Bruce written?
Sharon Bruce has written: 'Greater London transportation studies (GLTS)' 'Designing surveys using variances calculated from Census data' -- subject(s): Statistics
What are adverse variances?
Adverse variances means unfavourable variance which is actual expenses are more than budgted variance.
Which is the correct set of assumptions needed for comparing 3 or more means?
Equal variances, independent observations and normality
Why are separate price and quantity variances computed?
Price and quantity variances are computed respectively because different managers are usually responsible for buying and for using inputs.
Why are variances generally segregated in terms of a price variance and an efficiency variance?
Efficiency Varian materials and direct labor, the variances were recorded in specific general ledger accounts.
The formation of waves is a result of what?
Momentum transfer or pressure variances.
What does the F statistics tell you?
The difference between two variances
What are budget variances?
Budget variances are differences in expenditures from your original budgeted plan. This may happen if there is an expense during the month that one may not have planned for such as an automotive repair or doctor's bill.
