Text Solution

What is known?

Given numbers

What is unknown?

The mode and median of the data

Reasoning:

Mode \(=\) Mode is the observation that occurs highest number of times 

Median \(=\) Median is the middle observation 

Steps: 

Given data \(= 13, 16, 12, 14, 19, 12, 14, 13, 14\)

Arranging the data in ascending order, we get \(12, 12, 13, 13, 14, 14, 14, 16, 19.\)

\(∴\) Mode is the observation that occurs highest number of times.

\(∴\) Mode \(= 14\)

Also, median is the middle observation.

\(∴\) Median \(= 14\) (\(5\)th observation)
