As , we know " In statistics,

**modal class**refers to the group of statistical data that is made up of the highest frequencies. It is the**class**in the frequency distribution table, which is made up of the highest number of data points. we can see that both**modal class**and**median class**differ from each other .Hereof, what is median class?

The **median** is the middle term in the arranged data set. In the case of an even number of terms, the **median** is the average of the two middle terms. The **median class** interval is the corresponding **class** where the **median** value falls.

Subsequently, question is, how do you find the median of a class interval? **Summary**

- For grouped data, we cannot find the exact Mean, Median and Mode, we can only give estimates.
- To estimate the Mean use the midpoints of the class intervals: Estimated Mean = Sum of (Midpoint × Frequency)Sum of Freqency.
- To estimate the Median use: Estimated Median = L + (n/2) − BG × w.
- To estimate the Mode use:

Also to know is, what if there are two modal classes?

**If there** are more than one **class** intervals which have the same frequency (equally qualifying to be the mode **class**) then both of the **classes** will be the mode **class**. this is called bimodal.

How do you determine modal size?

To **find** the mode, or **modal** value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
