Find the mode and median of the data: 13,16,12,14,19,12,14,13,14

Solution

Step 1: Find the mode of the data

Mode is the value in the data that occurs most frequently.

Given data, 13,16,12,14,19,12,14,13,14

Arrange this in ascending order, we get 12,12,13,13,14,14,14,16,19

Upon observation, we can see that 14 occurs three times making it the most repeated variable.

So,mode=14.

Step 2: Find the median of the data

Median is the middle most value of the data.

The given data arranged in ascending order is 12,12,13,13,14,14,14,16,19

There are 9 observations (n) in total and we know that for an odd number of observations, median=valueofn+12thterm

So, the median term will be,

=9+12thterm=5thterm

So, the 5th term of the data is14.

Hence, both the median and mode of the given data is14.
