Thank you We sneak and here's your spoke to sure
- 00:05
brought to you by flying squirrels Sadly most of them
- 00:08
can only afford to travel in coach All right It
- 00:11
seems that the squirrels in town are having a rough
- 00:13
time finding food lately Our biologist friend collected some data

- 00:16
and we would like to put it into a frequency
- 00:19
hissed a gram because we have nothing better to do
- 00:21
with our time The data shows that five squirrels way
- 00:24
zero point five pounds seven way point five to one
- 00:27
pounds eight way One one and a half pounds Three
- 00:30
way One and half Two pounds one ways to two
- 00:32
and a half pounds and one large oval here weighs
- 00:35
three point five to four pounds This distribution of data
- 00:38
is what in squirrel ville here on here The potential
- 00:42
answers Okay so what's this question asking Well like our
- 00:47
nut loving friends over here we're going to go out
- 00:49
on a limb and say it's checking to see if
- 00:52
we know what a frequency history graham is Well if
- 00:55
we were to plot the data were given we'd have
- 00:57
a whole bunch of squirrels over here on the left
- 01:00
With big bars five of them way barely more than
- 01:03
a feather seven can register on a bathroom scale and
- 01:06
eight of them actually weigh more than a sixteen ounce
- 01:08
bottle of soda But then we get to the upper
- 01:10
weight class Just three squirrels fall in the one point
- 01:13
five two pound range and only one each fall into
- 01:16
the last two remaining boxes So while there are some
- 01:19
who are heavier it's clear that the pudgy squirrels are
- 01:22
something of an outlier and when we look at our
- 01:25
history graham well it's obvious that our data skewed right
- 01:28
Aii the bars on the right are shorter than the
- 01:31
ones on the left so our answer is be skewed
- 01:34
right Yeah well we hope some of the horizontally gifted
- 01:37
squirrels will have a heart and share their bounty with
- 01:40
the skinny minis Unfortunately we fear they'd find the mere 00:01:43.647 --> [endTime] suggestion to be well totally nuts
