 # Quick Answer: What Is Better A Positive Or Negative Variance?

## How do you explain variance?

The variance is the average of the squared differences from the mean.

To figure out the variance, first calculate the difference between each point and the mean; then, square and average the results.

For example, if a group of numbers ranges from 1 to 10, it will have a mean of 5.5..

## Should all variances be investigated?

How can variances be corrected? Variances should be investigated when variances are significant between actual costs and standard costs. … Significant variances must be reported as actual costs rather than standard costs, variances can be corrected with continual review and alterations when needed of standard costs.

## What does it mean to have a negative variance?

Negative variances are the unfavorable differences between two amounts, such as: The amount by which actual revenues were less than the budgeted revenues. The amount by which actual expenses were greater than the budgeted expenses. … The amount by which current revenues were less than the previous year’s revenues.

## How do you explain budget variance?

A budget variance is the difference between the amount you budgeted for and the actual amount spent. When preparing energy budgets, it is practically impossible to be “right on the money;” therefore resulting in a budget surplus or deficit.

## What does the variance tell you?

Variance measures how far a set of data is spread out. A variance of zero indicates that all of the data values are identical. … A high variance indicates that the data points are very spread out from the mean, and from one another. Variance is the average of the squared distances from each point to the mean.

## Can the variance ever be negative?

A large variance indicates that numbers in the set are far from the mean and from each other, while a small variance indicates the opposite. Variance can be negative. A variance value of zero indicates that all values within a set of numbers are identical. All variances that are not zero will be positive numbers.

## Which variance is always adverse?

Idle time varianceIdle time variance is therefore always described as an ‘adverse’ variance.

## Is a favorable variance always good?

We express variances in terms of FAVORABLE or UNFAVORABLE and negative is not always bad or unfavorable and positive is not always good or favorable. … A FAVORABLE variance occurs when actual direct labor is less than the standard.

## Is a negative cost variance good or bad?

Negative Versus Positive Variances Positive figures result if you spend less on a project than the budget predicted. Negative cost variance figures are almost always a bad thing for a business, as companies cannot always guarantee they can come up with the funds to cover the excess cost.

## Is variance always positive?

Variance is always nonnegative, since it’s the expected value of a nonnegative random variable. Moreover, any random variable that really is random (not a constant) will have strictly positive variance.

## How do you deal with variances?

The best way to manage variances is to have monthly reports and regular meetings to discuss these discrepancies with management and department heads. This also allows you to hold specific managers accountable for minimizing budget variance. Request a copy of the most recent budget.

## What causes unfavorable variances?

An unfavorable variance is the opposite of a favorable variance where actual costs are less than standard costs. Rising costs for direct materials or inefficient operations within the production facility could be the cause of an unfavorable variance in manufacturing.

## What does a positive expense variance mean?

A positive expense variance means that an actual expense differs from the amount in the budget.

## What is an example of a favorable variance?

Examples of Favorable and Unfavorable Variances Examples of favorable budget variances include: Reported revenues are more than planned revenues. Expenses are less than the planned budget. Manufacturing costs are less than the amount budgeted.

## How do you know if variance is favorable or unfavorable?

A variance is usually considered favorable if it improves net income and unfavorable if it decreases income. Therefore, when actual revenues exceed budgeted amounts, the resulting variance is favorable. When actual revenues fall short of budgeted amounts, the variance is unfavorable.

## What does it mean to have a Favourable variance?

A favorable variance is one where revenue comes in higher than budgeted, or when expenses are lower than predicted. The result could be greater income than originally forecast. Conversely, an unfavorable variance occurs when revenue falls short of the budgeted amount or expenses are higher than predicted.
