Mean, Median and Mode for Grouped Data The mean and median can be estimated from tables of grouped data. The class interval which contains the most values is known as the modal class .... When analyzing data, it is sometimes useful to temporarily "group" or "split" your data in order to compare results across different subsets. This can be useful when you want to compare frequency distributions or descriptive statistics with respect to the categories of some variable (e.g., Gender) - especially if you want separate tables of results for each group.

The basic purpose of this function is to calculate the median of given continuous grouped numeric data. The given data will always be in the form of sequence or iterator. Median is used to locate the central tendency of grouped numeric data....
The formula for variance and standard deviation for grouped data is very similar to the one for ungrouped data. Below, we show the formula for ungrouped data and grouped data. Population Sample . Ungrouped data Variance = Variance = Grouped data Variance = Variance = For grouped data, m is the midpoint of a class and f is the frequency of a class . Did you notice the similarity? Recall that a

How To Find Mean Of Grouped Data

And then comes the second part of my question -- while calculating the median of grouped data, if the value of $\frac{N+1}{2}$ ( or $\frac N2$) is a fraction, say 50.5, and there is a cumulative frequency 50, then what should we do? Should we take two median classes, one having cumulative frequency 50 and another coming next to it, and calculate two medians considering each of the median class
