Doubt in Practice Assignment Week 2

[Tamojit Midya]

In Question no 11, I cannot understand why option d) Size S jersey if it is the median of the size of jersey is a correct option. The question states that the physique of player A is similiar to most of the players in the team. Therefore, it indicates the mode of the given data can be jersey size of player A too. 

In Question no. 14, I cannot understand why the median will not change. Previously we took median of 43 players (median was 22) i.e. excluding players A & B. Now there are 45 players in total including A & B, therefore median will be 23. 

Please explain this.

Hello, 

For question 11 option D given that size S is median, since size S is the smallest size for it to be median at least 22 jerseys should be having size of S. If frequency of size S is greater than 22 it means that it is the mode because it is greater than half of total frequency (43).

Hello,

Yes, I have understood both the cases. For either case, median remains to jersey size of Player B as the jersey size of B was chosen to be the same as previous median. 

Can you also please suggest any additional books to follow to practice questions related to this topics?

Thank you.
