Question

find mean and median of the following data 5,9,8,6,8,7,6,7,9,8,7,9,7,8,5​

Answer 1

Answer:

ascending order- 5,5,6,6,7,7,7,7,8,8,8,8,9,9,9

n=15

median= (n+1) /2 th term

(15+1) /2 th term

16/2= 8 th term =7

mean = (5+5+6+6+7+7+7+7+8+8+8+8+9+9+9) /15

=109/15 = 7.266

Answer 2

Answer:

mean = 7.27

median = 7

Step-by-step explanation:

$Given \ data,\\ 5,9,8,6,8,7,6,7,9,8,7,9,7,8,5 \\\\ \boxed{\bf mean=\frac{sum \ of \ observations}{no.of \ observations} } \\\\\\ mean=\frac{5+9+8+6+8+7+6+7+9+8+7+9+7+8+5}{15} \\\\ mean=\frac{109}{15} \\\\ \implies mean=7.27 \\ -------------- \\\\ \boxed{median} \\\\ arrange \ in \ ascending \ order: \\ 5,5,6,6,7,7,7,7,8,8,8,8,9,9,9 \\\\ =>find \ the \ middle \ term\\ \implies middle \ term=7 \\\\ \implies median=7$
