Step 1: Definition of the median

** Median: **

** **The median of a set of data is the middlemost number in the set.

The median is also the number that is halfway into the set.

- If there is an odd number of observations, the median is the middle value.

let's say n is the number of observations

If n is odd, The median = \frac{n+1}{2}th term

- If there is an even number of observations, the median is the average of the two middle values.

If n is even, The median = \frac{\frac{n}{2}+\left(\frac{n}{2}+1\right)}{2}

Step 2: Arrange the data in either ascending order or descending orderr

Ascending order

0, 1, 5, 6, 6, 12, 19

Step 3: Count the number of observations and find the median of the given data

There are 7 observations

n = 7 is a odd number

So, the median = \frac{n+1}{2}=\frac{7+1}{2}=4^{th}\ term

See the 4th term in the data

0, 1, 5, 6, 6, 12, 19

Hence, the median = 6
