Question

Find the mean and the median of :
$1,3,4,5,9,9,$ and $11$

Answer 1

Given
Numbers are $1,3,4,5,9,9,$ and $11$
Hence, the mean can be calculated as below
Mean $=$(Sum of numbers) $/$ (Number of numbers)
$=(1+3+4+5+9+9+11)/7$
$=42/7$
We get,
$=6$
Hence, the mean is $6$
Total numbers are $7$
Since, total number of numbers is odd
Therefore, the median will be the middle number
Here, middle number is $5$
Therefore, the median is $5$
