Mean of Data given Variance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mean of Data = sqrt((Sum of Squares of Individual Values/Number of Individual Values)-Variance of Data)
Mean = sqrt((Σx²/N_Values)-σ²)
This formula uses 1 Functions, 4 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

Mean of Data - Mean of Data is the average value of all the data points in a dataset. It represents the central tendency of the data.
Sum of Squares of Individual Values - Sum of Squares of Individual Values is the sum of the squared differences between each data point and the mean of the dataset.
Number of Individual Values - Number of Individual Values is the total count of distinct data points in a dataset.
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

Sum of Squares of Individual Values: 62500 --> No Conversion Required
Number of Individual Values: 10 --> No Conversion Required

What is Mean and it's importance?

In Statistics, the most commonly used measure of central tendency is the Mean. The word 'mean' is the statistical term used for the 'average'. The mean can be used to represent the typical value and therefore serves as a yardstick for all observations. For example, if we would like to know how many hours on average an employee spends at training in a year, we can find the mean training hours of a group of employees. One of the main importance of the mean from the other measures of central tendencies is that, mean takes into consideration all the elements in the given data. It calculates the average value of the set of data. It cannot be an accurate measurement for skewed distribution. If the mean is equal to the median, then the distribution is normal.

How to Calculate Mean of Data given Variance?

Mean of Data given Variance calculator uses Mean of Data = sqrt((Sum of Squares of Individual Values/Number of Individual Values)-Variance of Data) to calculate the Mean of Data, Mean of Data given Variance formula is defined as the average value of all the data points in a dataset. It represents the central tendency of the data, and calculated using the variance of the data. Mean of Data is denoted by Mean symbol.

How to calculate Mean of Data given Variance using this online calculator? To use this online calculator for Mean of Data given Variance, enter Sum of Squares of Individual Values (Σx²), Number of Individual Values (N_Values) & Variance of Data (σ²) and hit the calculate button. Here is how the Mean of Data given Variance calculation can be explained with given input values -> 78.96835 = sqrt((62500/10)-625).

FAQ

What is Mean of Data given Variance?

Mean of Data given Variance formula is defined as the average value of all the data points in a dataset.
