## How do you use variance in a sentence?

Examples of variance in a Sentence

## Is it variance or variances?

var·i·ance. 1. The state or quality of being variant or variable; variation: considerable variance in temperature across the region.

## Is variance a real word?

the state, quality, or fact of being variable, divergent, different, or anomalous. an instance of varying; difference; discrepancy. Also called mean square deviation.

## What is the difference between variance and standard deviation?

Standard deviation looks at how spread out a group of numbers is from the mean, by looking at the square root of the variance. The variance measures the average degree to which each point differs from the mean—the average of all data points.

### What is the opposite of variance?

### How do you get the variance?

The variance for a population is calculated by:
1. Finding the mean(the average).
2. Subtracting the mean from each number in the data set and then squaring the result. The results are squared to make the negatives positive. ...
3. Averaging the squared differences.

### What is variance in statistics with example?

Unlike range and interquartile range, variance is a measure of dispersion that takes into account the spread of all data points in a data set. ... The variance is mean squared difference between each data point and the centre of the distribution measured by the mean.

### How do you interpret variance?

A large variance indicates that numbers in the set are far from the mean and far from each other. A small variance, on the other hand, indicates the opposite. A variance value of zero, though, indicates that all values within a set of numbers are identical. Every variance that isn't zero is a positive number.

### What is a request for 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 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.

### 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 is a sentence for variation?

"There is a slight variation in color." "There are different variations of that fairy tale." "That is a considerable variation to the original song."

### What does N represent in the formula for the population variance?

The term 'n1' represents the size of the first sample, and the term 'n2' represents the size of the second sample that is being pooled with the first sample. The term 's12' represents the variance of the first sample, and 's22' represents the variance of the second sample.

### How do you find the variance of a company?

To calculate a static budget variance, simply subtract the actual spend from the planned budget for each line item over the given time period. Divide by the original budget to calculate the percentage variance.

### What is the population variance of the data?

Population variance (σ2) tells us how data points in a specific population are spread out. It is the average of the distances from each data point in the population to the mean, squared.

### What are the properties of variance?

Informally, variance estimates how far a set of numbers (random) are spread out from their mean value. The value of variance is equal to the square of standard deviation, which is another central tool. Variance is symbolically represented by σ2, s2, or Var(X).

### What is the expectation of the variance?

Given a random variable, we often compute the expectation and variance, two important summary statistics. The expectation describes the average value and the variance describes the spread (amount of variability) around the expectation.

### What is a Deviat?

1 : one that deviates from a norm especially : a person who differs markedly from a group norm. 2 mathematics : a statistical variable that gives the deviation (see deviation sense b) of another variable from a fixed value (such as the mean) deviate.

### Which are measures of variance in a data set?

Measures of variability
• Range: the difference between the highest and lowest values.
• Interquartile range: the range of the middle half of a distribution.
• Standard deviation: average distance from the mean.
• Variance: average of squared distances from the mean.

### Is just another term for variance that is used in the analysis of variance?

1﻿﻿2﻿ ANOVA is also called the Fisher analysis of variance, and it is the extension of the t- and z-tests. The term became well-known in 1925, after appearing in Fisher's book, "Statistical Methods for Research Workers."3﻿ It was employed in experimental psychology and later expanded to subjects that were more complex.

### Should I use standard deviation or variance?

The SD is usually more useful to describe the variability of the data while the variance is usually much more useful mathematically. For example, the sum of uncorrelated distributions (random variables) also has a variance that is the sum of the variances of those distributions.
