Question

From 2000-2003, students were tested by the state in four major subject areas of math, science, English and social studies. The chart below displays average scores for all students at cherrybrook high school. In which subject did students score best on average across these four years.

Answer 1

To find average you add the scores from each subject and then divide them by how many different numbers you have.

Ex: 1+2+3=6
6/3=2

When you have the averages of all subjects over the 4 years, the one that is highest is your answer.

Hope this helps :)

Answer 2

As u have to find the average scores for all students. So, for finding the average of anything we always add them all and then divide them with the total number of objects. so, in this case, we will take the sum of all and divide them with their number and u will get the average of every student of four years in each subject.

And with the help of those, u will find the student who scores the best.
