### How do you average 2 test scores?

Let’s say you scored 90 percent on one test, but struggled on the other and got a score of 72 percent. To average the two scores, first add them together: 72 + 90 = 162 percent. Next, divide that result by the number of scores involved (in this case, two) to get the mean value or average: 162 ÷ 2 = 81 percent.

How do you calculate average score in one subject?

The average mark is equal to the sum of the scores divided by the number of subjects. Hence the average mark is 260/4 = 65. Therefore, the average marks scored in all the subjects is 65. Example 3: The weight(lb) of students in a class are listed here: {60, 55, 54, 53, 51, 62}.
