00:00:03.439 --> 00:00:06.099 A:middle L:90%
so looking for measures of variation. First, let's
2
00:00:06.099 --> 00:00:08.390 A:middle L:90%
put our data in order. It's much easier to
3
00:00:08.390 --> 00:00:11.369 A:middle L:90%
find the different pieces if our numbers are in order
4
00:00:11.699 --> 00:00:22.949 A:middle L:90%
. So we have a 15 a 34 43 64
5
00:00:24.640 --> 00:00:30.739 A:middle L:90%
60 73 92. So I've taken your data,
6
00:00:30.739 --> 00:00:32.450 A:middle L:90%
and I just put it, put those numbers in
7
00:00:32.450 --> 00:00:37.149 A:middle L:90%
order numerically as far as what they want. We're
8
00:00:37.149 --> 00:00:39.929 A:middle L:90%
looking for the range and so for the range,
9
00:00:39.929 --> 00:00:42.539 A:middle L:90%
we're gonna take the top number and subtract the lowest
10
00:00:42.539 --> 00:00:46.789 A:middle L:90%
number, so 90 to minus 15. Your range
11
00:00:46.789 --> 00:00:52.259 A:middle L:90%
in this case is 77. Then we're gonna look
12
00:00:52.259 --> 00:00:55.579 A:middle L:90%
for your like you are so for your i Q
13
00:00:55.579 --> 00:00:57.549 A:middle L:90%
r. You need your quartile. So first,
14
00:00:57.549 --> 00:01:00.149 A:middle L:90%
find the middle. So this is your median.
15
00:01:00.640 --> 00:01:04.450 A:middle L:90%
Which means then that this number is your lower quartile
16
00:01:06.140 --> 00:01:11.049 A:middle L:90%
and this number is your upper quartile. Excuse me
17
00:01:11.640 --> 00:01:14.629 A:middle L:90%
to find your range. You're looking for the difference
18
00:01:14.629 --> 00:01:19.250 A:middle L:90%
between those two. So 73 minus 34 gives me
19
00:01:19.250 --> 00:01:25.430 A:middle L:90%
an I Q. R of 39. Now,
20
00:01:25.430 --> 00:01:26.609 A:middle L:90%
if you're trying to determine if either of those are
21
00:01:26.620 --> 00:01:30.609 A:middle L:90%
outliers again, we're gonna take their 39 and we're
22
00:01:30.609 --> 00:01:34.019 A:middle L:90%
gonna multiply it by one point, which is going
23
00:01:34.019 --> 00:01:38.609 A:middle L:90%
to give us a total of 58.5. And that's
24
00:01:38.609 --> 00:01:44.079 A:middle L:90%
a pretty good size number. Um, so if
25
00:01:44.079 --> 00:01:46.409 A:middle L:90%
you look at your data, 34 is 15 is
26
00:01:46.409 --> 00:01:49.420 A:middle L:90%
not more than 58 away from 34. 92 is
27
00:01:49.430 --> 00:01:52.090 A:middle L:90%
It's only a difference of, like, 20 in
28
00:01:52.090 --> 00:01:53.650 A:middle L:90%
both cases, so you have no out liars.
29
00:01:56.640 --> 00:01:57.370 A:middle L:90%
So what do you have here? You have a
30
00:01:57.370 --> 00:02:01.239 A:middle L:90%
range on like you are, and there are no
31
00:02:01.250 --> A:middle L:90%
outlines.
