How to calculate the mean of grouped data?
- Determine the midpoint of each interval.
- Sum up all frequencies to obtain the number of samples.
- For each range of grouped data, multiply its midpoint by associated frequency. Add them all up.
- Divide this value by the number of samples.

Why does the variance use squares?
Variance uses squared differences from the mean to prevent obtaining negative values or zero due to canceling out the terms. It also weighs outliers more heavily than data closer to the average, so the differences are more significant.

What is the difference between standard deviation and variance?
Variance uses squares, whereas the standard deviation is expressed in the same units as the mean, so the latter is easier to interpret and use. However, you must calculate the variance to obtain the standard deviation.

Sample Variance of Grouped Data Calculator - MathCracker.com
October 9, 2019 - By using the midpoints are the representative of the values in the classes, we can use this familiar formula to get the variance of grouped data: \[ s^2 = \frac{ 1}{N-1}\left(\sum_{i=1}^n M_i^2 \cdot f_i - \frac{1}{N}\left(\sum_{i=1}^n M_i \cdot f_i \right)^2 \right) \] where the values \(M_i\) are the midpoints, \(n\) is the total number of classes, and \(N\) is the total sample size. You can also use this sample mean of grouped data calculator if you are instead interested in computing the sample mean, because you may be interested in analyzing the measures of central tendency as opposed to the measures of dispersion

March 7, 2022 - To calculate the mean for grouped data, we will use the data from Example 2: Height of students given in a tabular form below and calculate the midpoints of the intervals. The sum of observations is calculated by multiplying the frequency with the midpoint of the interval. The variance is an estimate of the degree of variability.
