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.

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.

How to find the midpoint of an interval?
The midpoint of an interval is an average of the interval's lower and upper limits. To find it:
- Add the lower limit to the upper limit.
- Divide this sum by 2. The result is the midpoint.

The standard deviation is 100. The raw score, for which we want to find a cumulative probability, is 1200. In this problem, we are dealing with a raw score, not a z-score; so, in the first dropdown box of the Normal Distribution Calculator, we select "raw score." And we want to find P(X โค 1200); so, in the second dropdown box we select "P(X โค x)" for probability. Next, we enter the following data: 1000 for population mean, 100 for standard deviation, and 1200 for the random variable (x).

How to Find Mean & Standard Deviation of Grouped Data
March 25, 2022 - The mean of the dataset turns out to be 22.89. Note: The midpoint for each group can be found by taking the average of the lower and upper value in the range. For example, the midpoint for the first group is calculated as: (1+10) / 2 = 5.5. We can use the following formula to estimate the standard deviation of grouped data:
