Considering the data that we have, we need to compute some measures.
00:04
So we can compute the range, which is the difference between the maximum value minus the minimum.
00:10
So in our case, this is 34 minus 15, which is 19.
00:17
We can also find what is the value of the first quartile, because we can use the first quartile and the third to find the interquartile range.
00:28
So the first quartile is the value in the position 0 .25 times the number of observations.
00:37
So in this case, because we have eight observations, this here is the position, the value in the second position.
00:45
But when i say the value in the second position, we need to have the values in an ascending order.
00:52
So basically, this is the second value from the smallest to the highest.
00:58
Which is 24.
01:00
If you do the same for the third quartile, is the value in the ascending order that is in the position 75 % times the simple size, which is 6.
01:12
And the value that is in the position number 6, when we have the data in ascending order, is 28...
