How do you use contrast in a sentence?
Is it a variance or variances? variance. 1. The state or attribute of being a variable or variable; Variation: A large variation in temperature across a region.
How do you explain the variance? A large variance indicates that the numbers in the group are far from the mean and far from each other. On the other hand, a small difference indicates the opposite. However, a variance value of zero indicates that all values within a set of numbers are identical. Every variance not equal to zero is a positive number.
Does it conflict with the meaning? If one thing is different from the other, they are completely different and seem to be opposing each other. The results contradict those in previous studies. Synonyms and related words. Opposes someone or something. opposed.

What is meant by cost variance?
Cost variance (CV) indicates the amount of increase or decrease in the project budget. Definition: The cost variance is the difference between the actual cost incurred and the planned/budgeted cost at a given time in the project.
What is asymmetry and its types?
The cost variance is the difference between actual expenses and expected (or budgeted) expenses. The cost variance equation usually consists of two components, namely: the volume variance.
What does standard deviation mean?
Standard deviation (or σ) is a measure of how dispersed the data is with respect to the mean. A standard deviation close to zero indicates that the data points are close to the mean, while a high or low standard deviation indicates that the data points are above or below the mean, respectively.
Who first used the term variance?

What is the difference in health care?
Patient variance is an offense that is related to the patient himself and not to the health care provider or facility. For example, the development of pressure ulcers as a result of patient immobility and poor nutritional status is an example of patient-related variability.
How do you explain the variance?
The variance refers to how the degrees of variance are distributed over the external distribution; That is, it indicates how much the scores are spread around the mean. For example, distributions with the same mean can have different amounts of variance or dispersion.
What does variance mean?
A variable, roughly by definition, is how far the data points in a statistical distribution or data set are apart from the mean value, as well as how different those data points are from each other.

As a general rule, CV > = 1 indicates a relatively high variance, while CV indicates Why is variance important?
The variance helps risk analysts determine the measure of uncertainty, which is difficult to measure without a standard deviation and variance. While uncertainty is not explicitly measurable, the variance and standard deviation allow analysts to determine the estimated impact that a particular stock can have on the portfolio.
What is variance in real estate?
In real estate, variance is an exception to local zoning law. Instead, it acts as a waiver of the zoning regulation, granted on a case-by-case basis for specific requests. Once a zoning variance is granted, it is run with the land, meaning that it is associated with the property rather than its owner.
What is the snake in the grass?

What are the main differences?
Variance analysis is an essential component of performance management and is the process by which the overall difference between the flexible standard and the actual results is analyzed. A number of basic differences can be calculated. If the results are better than expected, the variance is appropriate (F).
What is the cost difference and its importance?
Cost variance is the process of evaluating the financial performance of your project. The cost difference compares your budget that was set before the project started and what was spent. This is calculated by finding the difference between budgeted cost of work performed (BCWP) and ACWP (actual cost of work performed).
What is analysis of variance and how is it used?
Analysis of variance is used to evaluate the price and quantity of materials, labor and overhead costs. These numbers are reported to management. While it is not necessary to focus on every contrast, it becomes a signaling mechanism when the contrast is prominent.
What is the main purpose of analysis of variance?
Analysis of variance measures the differences between the expected results and the actual results of a production process or other business activity. Measuring and checking variances can help management contain and control costs and improve operational efficiency.
When should the standard deviation be used?
Standard deviation is used in conjunction with the mean summarizing continuous data, not categorical data. In addition, the standard deviation, like the mean, is only appropriate when the continuous data are not significantly skewed or have outliers.
What is the relationship between mean and standard deviation?
Standard deviation is a summary measure of the differences for each observation from the mean. The sum of squares is then divided by the number of observations minus the mean squares, and the square root is taken to return the measurements to the units we started with.
What is the difference with the example?
We know that variance is a measure of the prevalence of a data set. It is calculated as the mean squared deviation of each number from the mean of the data set. For example, for numbers 1, 2, and 3, the mean is 2 and the variance is 0.667. [(1 – 2)2 + (2 – 2)2 + (3 – 2)2] ÷ 3 = 0.667.

Examples of a common cause difference
Consider an employee who takes a little longer than usual to complete a particular task. He is given two days to do a task and, alternatively, two and a half days; This difference is a common cause.
Why is measuring difference in health care important?
Healthcare use can vary depending on where people live. Understanding variance across geographies is important to improving the quality, relevance and value of healthcare provided to patients.
