Okay, so i see that you need help with this question.
00:02
It wants you to construct a box plot of the data, and i'm gonna, it's 405, 420, 503, 531, 616, 634, 706, 756, 7 .58, 8 .50, 8 .81, 8 .90, 8 .95, 9 .09, 9 .09, 9 .23, 9 .28, 9 .50, 12 .50, and 12 .88.
00:45
Eight.
00:45
Okay.
00:46
So we have our minimum.
00:53
We have our maximum.
01:00
There is a total of one, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 values.
01:10
So between the 10th and the 11th number is going to be our median.
01:13
So one, two, three, four, five, five, six, seven, eight, nine, 10.
01:18
So our quartile two or our median, you're going to take 850 plus 881, divide that by two, and you're going to get 865 .5 is our median.
01:34
Then between the fifth and the sixth number, one, two, three, four, five is our quartile one.
01:41
So you're going to add 616 plus plus 634, divide that by two, and that's 625 is our quartile one.
01:53
And then one, two, three, four, five.
01:57
So if i take 909 plus 923, divide that by two, and i'm going to get 916.
02:06
And that is our quartile three.
02:09
So now i'm going to insert a number line.
02:14
Let's see, number line.
02:22
And you just make this smaller...
