Question

From the following data set, which number is occurring most number of times?

Answer 1

Step 1:

To find the frequency of each number of the given data set, we arrange the numbers in ascending order.

21	21	23	23	23
27	31	31	32	32

Step 2:

We now create a frequency table to determine the frequency or number of times each number appears.


We observe that the number 23 appears most number of times.

Hence, the mode of the given data set is 23.
