Question

The number of fiction books read by 30 pupils of class VII are as (4) follows: 4, 6, 1, 3, 7, 9, 5, 7, 9, 5, 4, 6, 10, 6, 9, 5, 5, 6, 8, 6, 8, 10, 9, 2, 1, 3, 2, 7, 2, 7 Construct a frequency distribution table for the above data and find its mode​

Answer 1

Step-by-step explanation:

The given data is

13, 16, 12, 14, 19, 12, 14, 13, 14

Arranging the given data in an ascending order,

12, 12, 13, 13, 14, 14, 14, 16, 19

Mode of a given data is that value of observation which occurs for the most number of times and the median of the given data is the middle observation when the data is arranged in an ascending or descending order.

As there are 9 terms in the given data, therefore, the median of this data will be the 5th observation.

Hence, median = 14

Also, it can be observed that 14 occurs 3 times (i.e., maximum number of times).

Therefore, mode of this data = 14
