00:00:01.639 --> 00:00:06.870 A:middle L:90%
this question shows you a table of the production of
2
00:00:06.879 --> 00:00:10.070 A:middle L:90%
bushels of wheat over the years. It s easy
3
00:00:10.070 --> 00:00:13.300 A:middle L:90%
to find the mean and the median. First,
4
00:00:13.300 --> 00:00:16.250 A:middle L:90%
we'll find that mean we know that the mean explore
5
00:00:16.739 --> 00:00:19.129 A:middle L:90%
is equal to the sum of all of our data
6
00:00:19.289 --> 00:00:22.699 A:middle L:90%
divided by the number. We know that our sample
7
00:00:22.699 --> 00:00:25.690 A:middle L:90%
size and is 10 here or 10 data points.
8
00:00:26.140 --> 00:00:28.379 A:middle L:90%
And when we plug all of this into our calculators
9
00:00:28.379 --> 00:00:30.519 A:middle L:90%
, we confined the X and that's some of the
10
00:00:30.519 --> 00:00:37.189 A:middle L:90%
exes is equal to 20,959. So it's a quick
11
00:00:37.189 --> 00:00:40.280 A:middle L:90%
step to explore. All we do is divide one
12
00:00:40.280 --> 00:00:43.670 A:middle L:90%
by the other, and we'll find that are mead
13
00:00:43.920 --> 00:00:55.890 A:middle L:90%
is 2959 point executing 2000 95 0.9. This also
14
00:00:55.890 --> 00:00:58.359 A:middle L:90%
wants us to find the median. And to do
15
00:00:58.359 --> 00:01:02.960 A:middle L:90%
that, I'm going to, uh, do a
16
00:01:02.960 --> 00:01:03.859 A:middle L:90%
little bit of a different method. Normally, what
17
00:01:03.859 --> 00:01:07.430 A:middle L:90%
I do is I put them all in order and
18
00:01:07.430 --> 00:01:10.099 A:middle L:90%
then count up. But instead of doing that,
19
00:01:10.099 --> 00:01:11.510 A:middle L:90%
I want to try something that will be a little
20
00:01:11.510 --> 00:01:15.099 A:middle L:90%
bit faster. We know that when n is 10
21
00:01:15.269 --> 00:01:21.709 A:middle L:90%
the median is theatric between the fifth entry and the
22
00:01:21.709 --> 00:01:26.310 A:middle L:90%
sixth entry. That's because right in the middle is
23
00:01:26.310 --> 00:01:30.219 A:middle L:90%
5.5. So we take the ones right next to
24
00:01:30.219 --> 00:01:33.120 A:middle L:90%
it and average those. So instead of putting them
25
00:01:33.120 --> 00:01:36.180 A:middle L:90%
all in order, I'm just gonna find the 1st
26
00:01:36.180 --> 00:01:38.480 A:middle L:90%
6 the lowest six and on average, five and
27
00:01:38.480 --> 00:01:41.599 A:middle L:90%
six and see what we get. So I go
28
00:01:41.599 --> 00:01:42.879 A:middle L:90%
through this list, I think the lowest one is
29
00:01:44.260 --> 00:01:52.700 A:middle L:90%
16,006 then 18,000 heat. Then 19,047 says three.
30
00:01:53.510 --> 00:02:00.030 A:middle L:90%
And I see 20,000. 51. 21,000 three and
31
00:02:00.030 --> 00:02:05.790 A:middle L:90%
21,057. So five and six right here to find
32
00:02:05.790 --> 00:02:07.579 A:middle L:90%
the media. And I just have to average those
33
00:02:07.730 --> 00:02:08.139 A:middle L:90%
. And when I do, I get that the
34
00:02:08.139 --> 00:02:13.849 A:middle L:90%
median is equal to 20,130 and that's
