Question

Each of 7 students reported the number of movies they saw in the past year. Here is what they reported. 16, 13, 19, 16, 8, 10, 10 Find the mean number of movies that the students saw. If necessary, round your answer to the nearest tenth.

Answer 1

13.1

Explanation:

Finding mean in data set is finding the average. The way to find the average is by adding all the data in the set (the # of movies watched), then divide them by how many numbers are in the data set (7).

16+13+19+16+8+10+10=92

After you add the data in the set, you have to divide it by the pieces of data there is.

So 92/7=

13.1428571

If you round 13.142...to the nearest tenth, you get 13.1.
