Question

Each of the 6 students reported the number of movies the saw in the past year.11, 17, 11,8, 15, 9find the Median & Mean number of movies that each student saw round to the nearest tenth

Answer 1

Solution

The median is the middle number in a sorted, ascending or descending, list of numbers

We need to arrange them in ascending order

8, 9, 11, 11, 15, 17

The middle numbers are 11 and 11

Median = (11 + 11)/2 = 11.

Mean is the sum (total) of all the values in a set of data, such as numbers or measurements, divided by the number of values on the list.

$\text{ Mean}=\frac{8+9+11+11+15+17}{6}\approx11.8$

Median is 11

The mean is 11.8
