Okay, the first question says compute the mean.
00:04
Now mean is given by the formula.
00:06
Summation of all the observations upon the number of observations.
00:10
This is nothing but the average, right? what is the number of observations that i have? 14, right? and what is going to be the summation of all of the values that i have? that is just do it.
00:23
2 plus 2 plus 4 plus 2 plus 2 plus 1 plus 2 plus 4 plus 3 plus 2 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3 plus 3.
00:32
So this is 31.
00:33
31 divided by 14.
00:35
So this is going to be 31 divided by 14, which happens to be 2 .21 if i'm not wrong.
00:45
2.
00:46
This is, yes, i'm not wrong.
00:52
This is 2 .21.
00:53
2 .214 if i want to be precise.
00:56
Okay.
00:57
So this is the average rating.
01:01
And average rating does make sense, right? so median will not make much of a sense, right? but average will give you the proper sense of measurement...
