above shows the electoral votes for the western part of
- 00:20
the united states Which of the following statements is true
- 00:23
and new land I mean senator range Another one of
- 00:29
those questions where there's only one truth teller and the
- 00:32
other three answer choices are liars liars with their pants
- 00:35
on fire No other way to approach a problem like
- 00:38
this Then teo take them one by one And fact
- 00:41
check him in order We'll start with option A mean
- 00:43
number of electoral votes is the same as the median
- 00:47
All right quick refresher on what those two words mean
- 00:49
incase we in conveniently forgot I mean is the same
- 00:53
as average where we total up all the values in
- 00:56
a data set then divide them by the number of
- 00:59
items The median is simply the middle of value in
- 01:03
the data set when the values are arranged from high
- 01:06
to low So to see if a is bogus or
- 01:09
not we're gonna have to write out all the state's
- 01:11
electoral votes starting with the small fries and going all
- 01:15
the way up to the big cheese You must be
- 01:18
getting close to lunchtime All right we'll hear those values
- 01:20
started from low to high few threes couple for three
- 01:24
five seven and nine a ten and eleven and a
- 01:28
bingle fifty five try to keep the bragging to a
- 01:31
venom of their california Totalling all these we get one
- 01:35
hundred twenty for which divided by thirteen The number of
- 01:38
states we just covered comes out to around nine and
- 01:40
a half which is not a match for the media
- 01:43
in which in this case is five So option a
- 01:46
can take a flying leap into the pacific ocean What
- 01:48
about beat Fifty percent of the state's have seven or
- 01:51
fewer electoral votes Let's look back at our order list
- 01:56
No way can easily see just by eyeballing the sucker
- 01:59
that there are only a few states with more than
- 02:02
seven votes while the clear majority has seven or fewer
- 02:06
buil d fall short as well Art option b is
- 02:09
the range of electoral votes Fifty eight Well the range
- 02:12
is the difference between the smallest and the largest value
- 02:16
In a data set in this instance the difference between
- 02:19
fifty five and three fifty two not fifty eight Like
- 02:24
the test question making their added and set us attracted
- 02:27
just tricky The order of our answer D the correct
- 02:33
answer is c The media number of electoral votes is
- 02:36
five Well yeah we figured that out way back when
- 02:40
you know when we eliminated off today so see it
- 02:42
is we're hawaii and alaska They get hardly any electoral
- 02:46
votes and they never get invited to any of the 00:02:49.065 --> [endTime] cool parties
