Sample variance refers to the sum of the squares of the standard deviation of a sample. This is one of the measures of central tendency and heavily impacts on the reliability of data. Sample variance simply measures the spread of a given data set and in most cases, the magnitude of the variance points to the **Capability Statements** of such sample to depict the real situation of the population.

Calculation of the sample variance proceeds along the known statistics regarding such data, which include the sample mean. The sample variance plays a key role in determining the spread of the data. Before calculation of this parameter, you have first to ensure that you have the sample mean, which indicates the average of the sample values. The sample, which is otherwise

## Variance Sample

Sample Variance Template is widely used by school & collage students, management trainee and professionals who are in research work. These Sample Variance Templates ensure that all the formulas are kept previously. So, it becomes easy for the user for putting the value and calculates the required result. It is available in easy printable version.

## Population Sample Variance

This is another type of sample variance template used in several organizations and research institutes who deals with statistical data. It features the required formula written at the top of the template and accordingly further calculation is arrived as well.

## Variance of Sample Mean

This is widely used for calculating theoretical mean and the variance accompanied by that. It also ensures that, there are sample problems are written in the document, where probable solution is also present. This type of template finds wide application in several research institutes and educational organizations.

## Variance of a Sample

It is quite different from the other two templates as it describes a graphical representation of the problem followed by the desired solution.

## Variance Problems

commonly known as the arithmetic mean is achieved by summing the values of the sample items and diving the sum by the number of items.

**In Simple Terms**

If the sample size is N and the items of the sample have values as X1, X2, X3,…, XN

The sample mean is achieved as follows:

( X1+X2+x3+…+XN)/N

This gives the sample mean, which is, abbreviates as ?.

You then calculate the variance by subtracting the mean from the sample values and squaring the result then summing up all the squares.

That is sum of (sample values-sample mean) ^2/ number of sample elements

**Factors that Affect the Sample Variance**

The sample variance needs closely relate to the values of the population. For this reason, the sampling technique highly influences the reliability of the sample variance value. Techniques that take into account the different elements of inconsistency in the population will give a more reliable value.

## Why These Sample Variance Templates are used?

Generally sample variance implies the sum of the squares of the standard deviation of a sample. It is related to the statistical measurement as it helps in measuring central tendency test. Sample variance has large impact on the reliability of data.

Sample variance simply measures the spread of a given data set and the magnitude of the variance points to the capability of such sample to depict the real situation of the population.

Thus, sample variance means, calculation of the sample variance proceeds along the known statistics regarding such data, which include the sample mean. To make the calculation easier this type of template is used.

## When Does Sample Variance Templates are used?

This type of template is widely used by various school students, management trainee and professionals who are in research work. As we all know, statistical method requires much concentration and a level of hard work. For minimizing this and make the work error free, this type of template is widely used.

Generally sample variance means a set of data based on which a particular value is calculated. If for an example, the sample size is N and the items of samples have values as X1, X2, X3 … XN, then the sample means achieved as follows: ( X1+X2+x3+…+XN)/N.

## Benefits of Sample Variance Template

Many organizations and research institutes are even failed to take any types of calculation instead of using this sample variance template. It helps in reducing manual intervention and ensures that the desired result should be achieved easily.

As this is widely used in various research institutes or even by school or college student, thus it ensures that, nominal error can be reduced. It also ensures that you can add value or other parameters as per the requirements of the user.

A Sample Variance Template features that, it can be customized and converted into the various file format to add more details and even attach their own logo to make it look more professional. It ensures that all the features can be further being custom made as per the particular necessities of the user.
