This question is given that mrs jones comes to you and asks how you calculated her 3rd grade student's math report card score.
00:08
Now the most likely way you would calculate this grade would be, now let's take a look at the definition of the four measures, there is mean, mode, range and median.
00:25
Now mean is the average, in this case average score of all the tests.
00:33
So it looks at all the tests and take the average, that is the sum of all the scores of the tests divided by the number of tests.
00:50
So this is very very fair.
00:54
Now mode is the most occurring score, that is the score that appears more, that is the highest frequency score.
01:11
So that is not a very good indication, like for example if the person's score is let's say 10, 20, 30, 30, 30, 40 and let's say 80, you will be taking 30 because 30 occurs more times than the rest...
