Okay t s i'ma shmoop er's Another boxy game for
- 00:05
you Look at this thing right here on the number
- 00:07
line which set of data points is represented by the
- 00:10
box and whisker plot below Okay well we're working backwards
- 00:20
here People check the rear view mirror and then shift

into reverse If we want to figure out which data
- 00:24
set produced the given box plot we need to understand
- 00:28
what a box plot shows us first that dot all
- 00:31
by itself While that's an outlier in the data set
- 00:33
it should be one single value well away from the
- 00:36
other values on the box The line in the middle
- 00:39
is the median The left end of the boxes the
- 00:41
twenty fifth percentile or first quarter tile or simply kyu
- 00:45
won the right into the box is the seventh percentile
- 00:48
or the third quarter mile or q three Well that
- 00:51
little mark on the end there The left whisker is
- 00:54
normally the lowest point in the data set But due
- 00:57
to the outlier it'll be the second lowest value in
- 00:59
the data set Well the market the end of the
- 01:01
right whisker There is the largest data point So after
- 01:04
grabbing the magnifying glass we can see the outlier Is
- 01:07
it to the second lowest data point is twelve ish
- 01:10
and the first court tiles about thirteen Well the median
- 01:13
looks sixteen ish and well Let's see q three seems
- 01:16
to be hanging out around eighteen ish and the max
- 01:19
value is probably about what is that twenty one Well
- 01:22
we've got to data sets that have an outlier too
- 01:24
Second lowest point of twelve and a maximum value of
- 01:26
twenty one looks like we need to check the median
- 01:29
and other court tiles of those two sets to make
- 01:31
a choice to get our answer here So let's think
- 01:34
about this Got all these numbers here that they have
- 01:37
a median of sixteen Kyu won is thirteen Q three
- 01:41
is eighteen Well that fits the bill exactly So that's
- 01:45
it that's the set of data We want its answer
- 01:48
b and well we're boxing whiskers smoked on this one
