mmr booster shot ever had one of those yet you're
- 00:24
bruised for a week Alright to analyze the data from
- 00:27
the bar graph Well first write it in ascending order
- 00:30
So we got our slacker shane here which were start
- 00:33
but it's like fifty sixty eighty ninety nine one hundred
- 00:36
one hundred ten twenty and forty that's it's everyone Well
- 00:38
the median of the data is the middle number while
- 00:41
we have ten data points so there isn't a single
- 00:43
middle number there too and the median is the average
- 00:46
of these two middle number's Luckily both middle number's air
- 00:49
ninety So the median is ninety Yeah that was anti
- 00:52
climactic Well the mean of the data is the average
- 00:55
which we calculate by adding everything up and then dividing
- 00:58
by the number of data points So we add all
- 01:00
these Numbers up then divide by 10 and we get
- 01:01
an average of ninety for right nine forty over ten
- 01:04
Well the media doesn't mean i don't have the same
- 01:06
value So one of these two is the exception will
- 01:09
calculate the mode and see if it's ninety or ninety
- 01:12
For whichever one it's not while that's the winner or
- 01:14
loser the mode of the data is the value that
- 01:17
repeats most frequently well ninety appears three times more than
- 01:21
any other value so the mode is ninety The media
- 01:24
in the mod have the same value so the exception
- 01:27
is the mean We also see that the range of
- 01:29
difference between largest and smalls values is also magically ninety
- 01:33
which seals the deal So the answer is b mean 00:01:36.74 --> [endTime] we are shmoop
