How do you explain variance in words?
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.
What is variance in simple terms?
The variance is a measure of variability. It is calculated by taking the average of squared deviations from the mean. Variance tells you the degree of spread in your data set. The more spread the data, the larger the variance is in relation to the mean.
What is another term for variance in stats?

What is the meaning of standard deviation and variance?
Variance is the sum of squares of differences between all numbers and means. Standard Deviation is square root of variance. It is a measure of the extent to which data varies from the mean.
Which variance is always an adverse variance?
Idle time variance is therefore always described as an ‘adverse’ variance.
What are the properties of variance?
Basic Properties of the Variance. One useful result about variances which is relatively easy to show is that because the variance gives a measure or the square of the width of a distribution, the variance of a constant times a random variable is the square of the constant times the variance of the random variable.

What is the formula for variance?
To calculate percentage variance, we can use the formula Variance = (new value-original value)/original value. This will give you a decimal number. After formatting this into percentage format you will get the result as a percentage.
What is the variance in statistics?
In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean. Informally, it measures how far a set of (random) numbers are spread out from their average value.
