00:00:00.540 --> 00:00:04.690 A:middle L:90%
So when we're being asked to determine whether this situation
2
00:00:04.690 --> 00:00:06.490 A:middle L:90%
would produce a random sample, I think there's two
3
00:00:06.490 --> 00:00:09.480 A:middle L:90%
main questions that we need to answer, which is
4
00:00:09.750 --> 00:00:12.449 A:middle L:90%
how are we picking people for the study or survey
5
00:00:12.839 --> 00:00:14.750 A:middle L:90%
, And then what is this? Study or survey
6
00:00:14.750 --> 00:00:17.320 A:middle L:90%
is supposed to be representing water. When we picked
7
00:00:17.320 --> 00:00:19.789 A:middle L:90%
this group of people and we serving them, what
8
00:00:19.789 --> 00:00:23.289 A:middle L:90%
are they supposed to represent? If we think that
9
00:00:23.300 --> 00:00:25.440 A:middle L:90%
the group of people that we have picked for this
10
00:00:25.440 --> 00:00:28.870 A:middle L:90%
survey would represent whatever this study is supposed to be
11
00:00:28.870 --> 00:00:31.350 A:middle L:90%
about, then yes, we consider it a random
12
00:00:31.350 --> 00:00:36.210 A:middle L:90%
sample because we would say that everyone in that sample
13
00:00:36.210 --> 00:00:38.750 A:middle L:90%
had an equal chance in a borough in the study
14
00:00:38.750 --> 00:00:41.570 A:middle L:90%
. Had an equal chance game picked right, eso
15
00:00:41.570 --> 00:00:43.600 A:middle L:90%
. In this case, it looks like how we're
16
00:00:43.600 --> 00:00:48.350 A:middle L:90%
picking people is we're, uh, asking every 20th
17
00:00:48.939 --> 00:00:55.859 A:middle L:90%
person can't right all of a sudden, every 20th
18
00:00:55.880 --> 00:01:00.079 A:middle L:90%
person, uh, let's see, says on a
19
00:01:00.079 --> 00:01:06.090 A:middle L:90%
list of registered voters, 20th person from a list
20
00:01:06.099 --> 00:01:14.239 A:middle L:90%
of registered voters. Okay, so that's how we're
21
00:01:14.239 --> 00:01:17.969 A:middle L:90%
getting our subjects. That's how we're getting our people
22
00:01:17.969 --> 00:01:19.159 A:middle L:90%
for this from the question is, what is this
23
00:01:19.159 --> 00:01:22.590 A:middle L:90%
? Study is supposed to represent, figure out that
24
00:01:22.590 --> 00:01:23.810 A:middle L:90%
sort of thing. Well, in this case,
25
00:01:23.989 --> 00:01:29.549 A:middle L:90%
it's supposed to be determining which political candidate is favored
26
00:01:36.700 --> 00:01:44.599 A:middle L:90%
which political candidate is favored. So if we take
27
00:01:44.599 --> 00:01:46.129 A:middle L:90%
a look at that and we think about this,
28
00:01:46.140 --> 00:01:49.200 A:middle L:90%
okay, if we're asking every 20th person from list
29
00:01:49.200 --> 00:01:53.569 A:middle L:90%
that is random in the sense that we're just asking
30
00:01:53.569 --> 00:01:56.730 A:middle L:90%
at a fixed interval or ads every 20th person,
31
00:01:56.730 --> 00:02:00.140 A:middle L:90%
we're not checking on anything, we're just asking that
32
00:02:00.140 --> 00:02:04.290 A:middle L:90%
. So that does make that random. But we
33
00:02:04.290 --> 00:02:06.629 A:middle L:90%
have to remember when we specifically talked about getting a
34
00:02:06.640 --> 00:02:08.909 A:middle L:90%
random sample. It doesn't just mean that we're talking
35
00:02:08.909 --> 00:02:12.990 A:middle L:90%
about finding people at random. It has to be
36
00:02:12.990 --> 00:02:15.210 A:middle L:90%
based off what we're trying to figure out in this
37
00:02:15.210 --> 00:02:17.830 A:middle L:90%
case. What we're trying to figure out is which
38
00:02:17.830 --> 00:02:22.409 A:middle L:90%
political candidate is favored? Well, when you consider
39
00:02:22.409 --> 00:02:24.379 A:middle L:90%
that, then no, this doesn't make sense,
40
00:02:24.379 --> 00:02:28.000 A:middle L:90%
because when you want to talk about political candidates being
41
00:02:28.000 --> 00:02:30.469 A:middle L:90%
favored, as you guys know, there's many different
42
00:02:30.479 --> 00:02:34.280 A:middle L:90%
political views, right? Different different people have different
43
00:02:34.280 --> 00:02:36.400 A:middle L:90%
political views. Eso you've got, you know,
44
00:02:36.400 --> 00:02:38.800 A:middle L:90%
different parties, you know, um could be Democrat
45
00:02:38.800 --> 00:02:42.599 A:middle L:90%
Republican, you know, could be libertarian. Could
46
00:02:42.599 --> 00:02:45.819 A:middle L:90%
be, you know, could be Communist you know
47
00:02:45.819 --> 00:02:47.590 A:middle L:90%
, it could could be any party that you have
48
00:02:47.590 --> 00:02:52.030 A:middle L:90%
certain views with. And so if we're just asking
49
00:02:52.030 --> 00:02:53.289 A:middle L:90%
every 20th person from a list of registered voters,
50
00:02:53.740 --> 00:02:57.639 A:middle L:90%
for all we know, we could be asking Onley
51
00:02:57.639 --> 00:03:00.360 A:middle L:90%
Democrats, right? We could have every 20 person
52
00:03:00.360 --> 00:03:01.240 A:middle L:90%
could just happen to be only democrats. We would
53
00:03:01.240 --> 00:03:04.550 A:middle L:90%
want to make sure that we have asked people from
54
00:03:04.550 --> 00:03:06.699 A:middle L:90%
all different parties. You'd also want to make sure
55
00:03:06.699 --> 00:03:08.719 A:middle L:90%
that you've asked people from different ethnicities, different backgrounds
56
00:03:08.719 --> 00:03:09.870 A:middle L:90%
, you know? Where were you born? You
57
00:03:09.870 --> 00:03:13.159 A:middle L:90%
know, that sort of thing. So in this
58
00:03:13.159 --> 00:03:15.500 A:middle L:90%
case, no, this does not represent a random
59
00:03:15.500 --> 00:03:20.759 A:middle L:90%
sample simply because while we are asking people at random
60
00:03:20.840 --> 00:03:23.050 A:middle L:90%
, we're not making sure it really represents everybody that
61
00:03:23.050 --> 00:03:27.210 A:middle L:90%
could vote because there are tons of different registered voters
62
--> A:middle L:90%
.
