Question

Each of 8 students reported the number of movies they saw in the past year. This is what they reported: 5, 4, 18, 19, 12, 20, 12, 12


Find the mean and median number of movies that the students saw.

If necessary, round your answers to the nearest tenth.

Mean: ? Movies
Median: ? Movies

Answer 1

Mean is just the average of all of them
So... 5 + 4 + 18 + 19 + 12 + 20 + 12 + 12 = 102
Then you divide that number by the amount of numbers you have so 102 / 8 = 12.75 or rounding it up to 13

For median you have to first put them in order from smallest to largest.
So 4 5 12 12 12 18 19 20
Then you have to find the middle number between them but in this case we have two... 12 and 12. Since they're the same number, the median is 12.
