Answer:
Median = 7 butterflies.
Step-by-step 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
[tex]n=7[/tex]
As we know:
[tex]Median = (\frac{n+1}{2})[/tex]
[tex]n=number\ of \ gruop\ of\ butterflies[/tex]
[tex]\frac{7+1}{2} =\frac{8}{2} = 4[/tex]
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.
