What is median class and modal class?
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 .
Also to know is, 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.
Also Know, 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:
Similarly, it is asked, 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.
