Answer :

(i). The statement is false.


To check this, we need to find mode of 2, 3, 9, 10, 9, 3, 9.


Count the data values:


2 appears 1 time


3 appears 2 times


9 appears 3 times


10 appears 1 time


9 appears most of the times, that is, 3 times.


Thus, mode is 9.


Hence, the statement given is false.


(ii). The statement is false.


To check this, we need to find median of 3, 14, 18, 20, 5.


Arrange the data into ascending order. We get


3, 5, 14, 18, 20


Total number of values, n = 5


Since n is odd, median is given by





Median = 3rd term


Thus, median is 14.


Hence, the statement is false.
