Find the mode of the following data:

(i) 2 5 7 5 3 1 5 8 7 5

(ii) 2 4 6 2 6 6 7 8

(iii) 2.5 2.5 2.1 2.5 2.7 2.8 2.5

(i) We know that, the mode is one with highest frequency, i.e., the one repeats the most.

Here, 5 is repeated four times.

⇒ Mode = 5

(ii) We know that, the mode is one with highest frequency, i.e., the one repeats the most.

Here, 6 is repeated three times.

⇒ Mode = 6

(iii) We know that the mode is one with highest frequency, i.e., the one repeats the most.

Here, 2.5 is repeated four times.

⇒ Mode = 2.5
