five All right Well poles might seem super scientific with
- 00:21
all their decimals and prevented signs and whatnot but they
- 00:24
can't claim to be exactly right one hundred percent of
- 00:26
the time See what we did there will do Scientific
- 00:30
polls contain a margin of error of plus or minus
- 00:32
a one percent Well the margin of error basically means
- 00:35
how much wiggle room you have when you're giving your
- 00:38
exact answer But one percent seems a little too small
- 00:41
So let's look for something that gives us a bit
- 00:43
more room to groove Good The margin of error of
- 00:45
plus or minus two percent Stupid question This is by
- 00:48
the way who is certainly better than one But we're
- 00:50
still a little too thin around the margins here So
- 00:52
he's more of a bus Well we're going to skip
- 00:55
to d what should i tell you What The answer
- 00:57
Is how about four percent Well four certainly evens things
- 01:00
out of it but we might have gone a little
- 01:01
too far in the wrong direction What about e five
- 01:04
percent Well what if we got a seventy ana tasked
- 01:07
with a plus or minus five percent huh Pretty wide
- 01:10
swing That means that scientific polls contain a margin of
- 01:13
error of plus or minus three percent You know who
- 01:16
made that law for three percent but that's how they
- 01:18
do it three percent a bit of an arbitrary cut
- 01:20
off But it's generally accepted standard for poles of finding
- 01:24
a fifty percent with a three percent margin of error
- 01:27
means that the real answer if you could ask all
- 01:30
members of the population would range somewhere between forty seven
- 01:33
and fifty three percent So c is the correct answer
- 01:36
Margins of error alleviate the pressure to be exact one
- 01:39
hundred percent of the time making it easier when you
- 01:42
have to dig yourself out of a particularly bad fool 00:01:46.834 --> [endTime] don't don't
