Standard Deviation given Variance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Standard Deviation of Data = sqrt(Variance of Data)
σ = sqrt(σ²)
This formula uses 1 Functions, 2 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Standard Deviation of Data - Standard Deviation of Data is the measure of how much the values in a dataset vary. It quantifies the dispersion of data points around the mean.
Variance of Data - Variance of Data is the average of the squared differences between each data point and the mean of the dataset. It quantifies the overall variability or spread of the data points around the mean.

STEP 1: Convert Input(s) to Base Unit

What is Standard Deviation in Statistics?

In Statistics, the Standard Deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. A useful property of the standard deviation is that, unlike the variance, it is expressed in the same unit as the data. The Standard Deviation of a random variable, sample, statistical population, data set, or probability distribution is defined and calculated as the square root of its variance.

How to Calculate Standard Deviation given Variance?

Standard Deviation given Variance calculator uses Standard Deviation of Data = sqrt(Variance of Data) to calculate the Standard Deviation of Data, Standard Deviation given Variance formula is defined as the measure of how much the values in a dataset vary. It quantifies the dispersion of data points around the mean, and calculated using the variance of the given data. Standard Deviation of Data is denoted by σ symbol.

How to calculate Standard Deviation given Variance using this online calculator? To use this online calculator for Standard Deviation given Variance, enter Variance of Data (σ²) and hit the calculate button. Here is how the Standard Deviation given Variance calculation can be explained with given input values -> 2 = sqrt(6.25).

FAQ

What is Standard Deviation given Variance?

Standard Deviation given Variance formula is defined as the measure of how much the values in a dataset vary. It quantifies the dispersion of data points around the mean, and calculated using the variance of the given data and is represented as σ = sqrt(σ²) or Standard Deviation of Data = sqrt(Variance of Data). Variance of Data is the average of the squared differences between each data point and the mean of the dataset. It quantifies the overall variability or spread of the data points around the mean.

How to calculate Standard Deviation given Variance?

Standard Deviation given Variance formula is defined as the measure of how much the values in a dataset vary. It quantifies the dispersion of data points around the mean, and calculated using the variance of the given data is calculated using Standard Deviation of Data = sqrt(Variance of Data). To calculate Standard Deviation given Variance, you need Variance of Data (σ²). With our tool, you need to enter the respective value for Variance of Data and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Standard Deviation of Data?

In this formula, Standard Deviation of Data uses Variance of Data. We can use 3 other way(s) to calculate the same, which is/are as follows -

Standard Deviation of Data = (Mean of Data*Coefficient of Variation Percentage)/100
Standard Deviation of Data = sqrt((Sum of Squares of Individual Values/Number of Individual Values)-(Mean of Data^2))
Standard Deviation of Data = Mean of Data*Coefficient of Variation Ratio
