So for this problem, we are asked for the five -number summary given the frequency table.
00:05
Now, our five -number summary is going to be minimum, first quartile, median, third quartile, then maximum.
00:16
So right off the bat, we can see the minimum and maximum values would be three and 24.
00:21
Then for finding our different quartiles and the median, those are basically what values would constitute a particular percentile of the data.
00:30
So what i'll do first is figure out the total of all of our data.
00:36
So we have 6 plus 2 plus, actually, i'll just bring up, i put this into excel previously.
00:42
So we have the sum is 27.
00:46
So, or actually let me just double check that.
00:50
Yeah, the sum of the selected data is 27.
00:52
Okay.
00:53
So what we'd want to do is first find what 0 .25 times 27 is going to be.
00:59
Or actually, let me correct myself here.
01:02
The first thing that we want to do is note that because we have n equals 27, we have that the median value, the median value is going to be the value such that we are at basically n minus 1 over 2 plus 1, or n plus 1 over 2...
