00:00:00.870 --> 00:00:02.810 A:middle L:90%
this question gives you a list of data and asks
2
00:00:02.810 --> 00:00:06.150 A:middle L:90%
you to find the median. The data that it
3
00:00:06.150 --> 00:00:16.179 A:middle L:90%
gives is 28.4, 9.13 point four, 27.6,
4
00:00:17.519 --> 00:00:31.989 A:middle L:90%
59.8, 32.1, 47.6 and 29 points. Now
5
00:00:31.989 --> 00:00:33.850 A:middle L:90%
, before we can find a median, we need
6
00:00:33.850 --> 00:00:36.579 A:middle L:90%
to put this in order. That is, um
7
00:00:37.140 --> 00:00:39.880 A:middle L:90%
, rearrange this. So it's going from lowest to
8
00:00:39.880 --> 00:00:42.750 A:middle L:90%
highest rise lowest. I'm gonna do lowest to highest
9
00:00:42.929 --> 00:00:47.750 A:middle L:90%
doing that. We'll get 3.49 point one. Um
10
00:00:47.750 --> 00:00:54.560 A:middle L:90%
, next is 27.6, then 28.4 than ah,
11
00:00:54.570 --> 00:01:02.619 A:middle L:90%
29.8. Then we'll get 32.1, 47.6. And
12
00:01:02.619 --> 00:01:06.079 A:middle L:90%
finally, the last 59.8. So now it's an
13
00:01:06.090 --> 00:01:08.189 A:middle L:90%
order. And when we have an ordered list of
14
00:01:08.409 --> 00:01:11.590 A:middle L:90%
length N, we know that the median is at
15
00:01:12.209 --> 00:01:17.260 A:middle L:90%
entry and plus one over to that is endless.
16
00:01:17.260 --> 00:01:18.950 A:middle L:90%
1/2 will give us a number, and then we
17
00:01:18.950 --> 00:01:22.870 A:middle L:90%
count that number into the, uh list, and
18
00:01:22.870 --> 00:01:26.590 A:middle L:90%
we'll find her media. Here we have 88 points
19
00:01:26.590 --> 00:01:27.629 A:middle L:90%
. So we'll have, uh, are meeting will
20
00:01:27.629 --> 00:01:30.549 A:middle L:90%
be a 0.8 plus 1/2, which is 9/2,
21
00:01:30.549 --> 00:01:34.890 A:middle L:90%
which is 4.5. How do we have a median
22
00:01:34.890 --> 00:01:37.000 A:middle L:90%
at 0.4 point five week? Uncounted in love?
23
00:01:37.189 --> 00:01:41.730 A:middle L:90%
123 Here's 1230.4, and here's 0.5. How do
24
00:01:41.730 --> 00:01:44.430 A:middle L:90%
we have a median right in the middle? Well
25
00:01:44.430 --> 00:01:46.180 A:middle L:90%
, when this happens and this will happen whenever you
26
00:01:46.180 --> 00:01:49.450 A:middle L:90%
have a even number of data points, what you
27
00:01:49.450 --> 00:01:52.420 A:middle L:90%
have to do is you take the point right below
28
00:01:52.420 --> 00:01:55.920 A:middle L:90%
it and the point right above it, and average
29
00:01:55.920 --> 00:01:59.650 A:middle L:90%
those. So we're gonna averaged 28.4 in 29.5.
30
00:02:00.439 --> 00:02:06.030 A:middle L:90%
Um, And when we do that shooting at 25
31
00:02:06.030 --> 00:02:09.349 A:middle L:90%
. 20.8, when we do that divide by two
32
00:02:09.789 --> 00:02:15.050 A:middle L:90%
, we get the average is 29.1 and that is
33
00:02:15.060 --> 00:02:16.870 A:middle L:90%
your median, your median of the set
