Question

In which subject did students score best on average across these four years?

Answer 1

Mathematics level 2 is the highest with the research I have been doing.

Answer 2

Answer with Explanation

To discover average you include the scores from each subject and afterward separate them by what number of various numbers you have.  An example is shown below, like if there were three subjects who got different scores. The next step would be to add the score of all subjects.

Example

- 1+2+3=6  

After adding the total sum will be divided by the number of students.

- 6/3=2  

When you have the midpoints of all subjects over the 4 years, the one that is most noteworthy will be answer.
