Okay, let's start.
00:04
So first in order to do the question, we have to arrange the numbers from the correct order.
00:12
Now they are in random order, we have to organize them from lowest to highest, or highest to lowest.
00:19
Anyways, for example, the lowest or the minimum is 21, and all the way we find the highest to be 75, the maximum.
00:32
Okay, so i did my arranging on my paper, but here is what i have.
00:40
So first, we have to find all the five number values.
00:46
They are essential for box plot.
00:49
So what i find is that minimum is 21, q1 is 37.
01:03
The median, in this case, it's even number.
01:07
It has 46 numbers, right? so we are taking the average of the 23rd and the 24th, the average.
01:21
It is to be 45 .5.
01:26
And q3, 55 maximum, 75.
01:33
So what happened is this is the first number, the first number or the minimum.
01:41
This one should be the 12th, this one is the middle of 23 and 24, this one to be 35th, this one to be the last, which is the 46th number.
02:03
So once again, minimum q1, median q3, and maximum.
02:19
Now we have our 5 number.
02:25
Now we need to find the iqr.
02:27
So iqr is the interquartile range.
02:33
Iqr equals q3 minus q1.
02:41
Okay, so in this case, it is 18.
02:45
And now we need to find the upper fence and lower fence for the box plot...
