So how can i determine if there's any outliers in a set? well, there could be an upper bound outlier.
00:07
The upper bound is going to be the third quartile plus 1 .5 times the inner quartile range.
00:14
And then there's a lower bound outlier.
00:18
And this is quartile 1 minus 1 .5 times the intercortile range.
00:22
So first, let's find me the intercortile range.
00:26
How do i calculate this? well, this is just quartile 3 minus quartile 1.
00:30
So let's first find this.
00:32
So let's list these numbers from least to greatest.
00:34
So i have zero.
00:36
And then my next greatest number is i have two twenties.
00:40
20 -20.
00:41
What else? i have one, two, three, four, 23s.
00:47
So one, two, three, four.
00:49
And then i have a 28, 43, and an 80.
00:54
Okay, so let's find first my median.
00:58
So my median, cross off one on each side...
