Median = 7 butterflies.

Explanation:

Given:

Omar volunteered at the city botanical gardens, recording the number of butterflies attracted by each of the 7 exhibits. He recorded :-

7, 9, 7, 9, 6, 6, 8

Question asked:

What was the median number of butterflies recorded?

Solution:

First of all we will set these data in ascending order:

6, 6, 7, 7, 8, 9, 9

`n=7`

As we know:

`Median = ((n+1)/(2))`

`n=number\ of \ gruop\ of\ butterflies`

`(7+1)/(2) =(8)/(2) = 4`

That means 4th data is the median.

6, 6, 7, 7, 8, 9, 9

Therefore, the median number of butterflies recorded at the city botanical gardens is 7 butterflies.
