00:01
So it says complete the frequency distribution table.
00:03
And again, i don't see your table.
00:07
So if, and then it says, please use the chart as guided to it and ignore the numbers in the columns, then draw a histogram to represent the data.
00:16
And then after, we have to find which class has the most numbers in the quizzes and so on.
00:21
So i don't know how wide your values are.
00:25
So you do have a total of 30 numbers.
00:29
And so let's say i put all of these into a list.
00:34
And i'm going to use my second list feature.
00:38
And i'm going to sort ascending.
00:40
That way, my values are all in order.
00:43
So when i look at my list, i've got them all in order.
00:47
Now, again, you have values that are as low as 19 is the low.
00:54
And it goes as high as a number of 50, i believe.
01:00
Yes, 50 is your high.
01:03
So if i take that difference, typically if i'm trying to figure out how big of a, to make each class, if i take 50 minus the 19, we know that that value is 31.
01:14
And let's say i wanted to have about six classes.
01:19
So if i divided that by 6, i would roughly have about five in each class.
01:25
So let's say i had them go from 15 up to, but not including, so up to 19, and then 20, up to 24, 25, up to 30.
01:45
Oops, that should be 29.
01:47
Shouldn't it? and then we have 30 up to 34, 35 up to 39.
02:01
And then, in fact, how about i'm going to do a little change here.
02:05
So let me pause, and you'll see what i'm doing.
02:09
Ok, i'm going to decide to have this one go from 16 up to 20, and this one go 21 to 25, and have the end of the class be the 30, 35, 40, and then the 45 and 50.
02:26
And so i don't know if this is what you have, 26.
02:30
This is 31.
02:31
This is going to be 36, and this is going to be 41.
02:37
And then this will go from 46 to 50...
