A teacher gives a 10-point to a class of 10 children.
1 answer:
Given what we know, we can say that it is possible for 9 out of 10 students to score above average, but it is not possible for all 10 to score above average.
<h3>How do we calculate an average score?</h3>In order to calculate the average score of the students, we must use addition.
We have to add all of the scores, in this case, 10 scores, and then divide by the number of scores.
One example of 9 out of 10 students scoring above average would be:
This would leave us with an average score of 8.2 and 9 out of 10 students that have scored higher.
Given the way in which we calculate average scores, it is impossible for all 10 students to score above average since even if all 10 students get a perfect score, that would then become the average.
