Answer: Mean = 9.3

Median = 10

Mode = 13

Explanation:

The given data : 15, 13, 9, 9, 7, 1, 11, 10, 13, 1, 13

First arrange then in ascending order.

1, 1, 7, 9, 9, 10, 11, 13, 13, 13, 15

Now,
$\text{Mean}=\frac{\text{Sum}}{\text{Number of observations}}$

$\text{Mean}=(102)/(11)=9.727\approx9.3$

Since, the number of observations = 11 .....odd number.

Therefore, Median =
$(11+1)/(2)=6^(th)\ term=10$

Mode = Most repeated number = 13
