The test scores of five students for the first two test of the semester are shown in the table below.

A

Step-by-step explanation:

Take test score from Test 1 and add them all together and divide by the number of test

ex) 77+82+69+85+93=406

    406/5= 81.2

Then repeat with Test 2

ex) 75+76+71+68+72=362

    362/5= 72.4

Therefore the MAD of Test 1 > MAD of Test 2

the answer is A.

Step-by-step explanation:

Add the test scores of the first test together then add the test scores of the second test together then compare and contrast.

there are no short passages to look at
