Question

Deanna's scores for a computer game are 18, 20, 22, 25, 12, and 20. Lilly's scores are 20, 20, 21, 21, 16, and 16. Who has the higher mean score? By how much?

Answer 1

Answer: Deanna has the higher mean score by .5

Step-by-step explanation: The important piece of information to remember here is that the mean is the average. In order to solve the question, the first thing that you need to do is calculate the average of each of their scores.

Deanna = 18+20+22+25+12+20 = 117

The mean = 117/6 = 19.5

Lilly = 20+20+21+21+16+16 = 114

The mean - 114/6 = 19

Answer 2

Deanna and by 0.5. Deanna’s mean (or average) is 19.5, and Lily’s is 19. You solve this by adding all of the numbers for each person and dividing it by 6.(the number of numbers) Hope this helped I just learned this.
