Question

Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 16, 12, 13, 14, 19, 13, 17, 13 Find the mean and median number of movies that the students saw. If necessary, round your answers to the nearest tenth.

Answer 1

Mean: 14.6

Median: 13.5

Explanation:

To find the mean, add up all the numbers and divide by the amount of terms:

`(16+12+13+14+19+13+17+13)/(8)=(117)/(8) =14.625`

To find the median, order the numbers from least to greatest and take the center term:

12, 13, 13, 13, 14, 16, 17, 19

If there is an even number of terms, average the middle two:

`(13+14)/(2)=13.5`

Answer 2

The median is the average of all the numbers so you would first add all the numbers together which is 16+12+13+14+19+13+17+13=117

then you divide 117/8=14.6

Then your median is the middle number of all your numbers in numerical order

12, 13, 13, 13, 14, 16, 17, 19

which is 13 and 14, and between those two numbers is 13.5
