Important Doubt

[Pranjal Sarkar]

Hello team

While practicing AQ2.5 Q.No.4, I recalled that while finding the median or mode of any ordinal variable, we have to arrange them in order(ascending or descending).

I have provided a picture, where it shows a graph for no. of students based on they are good, average or bad.

It goes like, there are:

10 good students,

20 average students, 

15 bad students

In the graph, good, average, and the bad are arranged in ascending order of whether they are good or average or bad.

Question 1. Now, what is the mode and median of the number of students who are either good/average/bad?

Here for the answer what do we write?

Do we write the numerical value of 20 or average as the answer(this is for median) or something else?

Question 2. What is the mode and median grade in the graph?

I have attached a picture file. Please find the same.

P.S.: Please don't mind the handwriting.

Thank you

Hi, Pranjal

Question 1) First of all, it should be the median of data not the median of number of students. Since the median is defined as a middlemost observation. Hence, When you are arranging them in increasing order then the middle observation will be the median, not its frequency. Hence answer will be average, not 20.

I can not see the variable grade in the graph for question 2.

Thanks,
