What exactly is variance? What Is Variance? The term variance refers to a statistical measurement of the spread between numbers in a data set. More specifically, variance measures how far each number in the set is from the mean and thus from every other number in the set.
Considering this, What variance means?
Definition of variance
1 : the fact, quality, or state of being variable or variant : difference, variation yearly variance in crops. 2 : the fact or state of being in disagreement : dissension, dispute. 3 : a disagreement between two parts of the same legal proceeding that must be consonant.
Subsequently Is high variance good or bad? Variance is neither good nor bad for investors in and of itself. However, high variance in a stock is associated with higher risk, along with a higher return. Low variance is associated with lower risk and a lower return. … Variance is a measurement of the degree of risk in an investment.
How much variance is high?
As a rule of thumb, a CV >= 1 indicates a relatively high variation, while a CV < 1 can be considered low. This means that distributions with a coefficient of variation higher than 1 are considered to be high variance whereas those with a CV lower than 1 are considered to be low-variance.
How do you get the variance?
How to Calculate Variance
- Find the mean of the data set. Add all data values and divide by the sample size n. …
- Find the squared difference from the mean for each data value. Subtract the mean from each data value and square the result. …
- Find the sum of all the squared differences. …
- Calculate the variance.
What does variance mean in accounting?
In budgeting (or management accounting in general), a variance is the difference between a budgeted, planned, or standard cost and the actual amount incurred/sold. Variances can be computed for both costs and revenues.
What is another name of variance?
What is another word for variance?

What is an acceptable variance?
What are acceptable variances? The only answer that can be given to this question is, “It all depends.” If you are doing a well-defined construction job, the variances can be in the range of ± 3–5 percent. If the job is research and development, acceptable variances increase generally to around ± 10–15 percent.
What is a good variance percentage?
It should not be less than 60%. If the variance explained is 35%, it shows the data is not useful, and may need to revisit measures, and even the data collection process. If the variance explained is less than 60%, there are most likely chances of more factors showing up than the expected factors in a model.
What does a high variance tell you?
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.
What is a bad variance?
Definition of Negative Variances on Accounting Reports
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.
What is a low variance value?
A model with low variance means sampled data is close to where the model predicted it would be. A model with high variance will result in significant changes to the projections of the target function.
What does it mean to request a variance?
Essentially, a property owner requests a variance when their planned use of their property deviates from local zoning laws designed to protect property values. If granted, a variance acts as a waiver to some aspect of the zoning law or regulations.
What is the meaning of variance in accounting?
In budgeting (or management accounting in general), a variance is the difference between a budgeted, planned, or standard cost and the actual amount incurred/sold. Variances can be computed for both costs and revenues.
What does variance mean in business?
Variance is the difference between the budgeted/planned costs and the actual costs incurred. … Businesses often carry out variance analysis – a quantitative investigation into the differences between planned and actual costs and revenues. Variance analysis can be applied to both revenues and expenses.
What is job variance?
A WIP variance occurs if the actual material and labor costs for the job differs from the standard cost defined against the item. If the variance is negative, then it indicates that the total material cost is greater than the total transaction cost defined against the warehouse.
How do you explain variance?
When standards are compared to actual performance numbers, the difference is what we call a “variance.” Variances are computed for both the price and quantity of materials, labor, and variable overhead, and are reported to management. However, not all variances are important.
Is variance actual minus budget?
A budget variance is the difference between the budgeted or baseline amount of expense or revenue, and the actual amount. … Those budget variances that are controllable are usually expenses, though a large portion of expenses may be committed expenses that cannot be altered in the short term.
What is a high variance?
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. The process of finding the variance is very similar to finding the MAD, mean absolute deviation.
How do you calculate variability?
Measures of Variability: Variance
- Find the mean of the data set. …
- Subtract the mean from each value in the data set. …
- Now square each of the values so that you now have all positive values. …
- Finally, divide the sum of the squares by the total number of values in the set to find the variance.
What is the opposite of variance?
variance. Antonyms: unity, reconciliation, harmony, agreement, pacification, peace, accommodation, consent. Synonyms: difference, disagreement, discord, estrangement, antagonism, strife, hostility, discrepancy.
What does variance mean in finance?
A variance is the difference between actual and budgeted income and expenditure.
What does high variance mean?
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.
