Q4 of 55 Page 364

The frequency distribution table shows the selling prices of shoes of a special company of shoe shop of our village.

Since, mode is just the data value/s appearing most often in given set of data values.

We just need to search for the size which has the greatest frequency. Frequency is just the number of occurrence of the data value.


Here,


2 appears → 3 times


3 appears → 4 times


4 appears → 5 times


5 appears → 3 times


6 appears → 5 times


7 appears → 4 times


8 appears → 3 times


9 appears → 2 times


⇒ 4 and 5 appears most of the times, that is, 5 times.


Thus, mode is 4 and 5.
