So here i'm going to note that there's a limited amount of detail that i can go into when answering this problem because, unfortunately, with the original upload, i don't have the data necessary.
00:13
So what i'm going to do is i'm going to just create some data here using a random number generation.
00:26
So we have teen and we have adult.
00:29
And let's say we want a random array, or just i'll generate some random numbers between, and let's see here, it's the number of texts.
00:42
So let's say it's between zero and 100.
00:48
So i'll generate 30 for the teens, and then for the adults, i'll generate 83.
00:59
This is partly going to be just to emphasize the fact that there is a reason why we use.
01:05
Use relative frequency distributions rather than absolute frequencies.
01:09
But also what i'm going to do, you might see that whenever i do something, all of my data gets recalculated.
01:15
So i'm going to copy and paste the exact values there and then wipe out that original sample, just so that now we're working with a sort of fixed dataset.
01:28
So for our frequency distribution, what we'll want to do, because i know ahead of time here that there are is a um the the total range is going to be from zero to 100 generally speaking uh and i know that for the first data set okay what i'll do is for figuring out the bin widths um there's a lot more data for the adults than for the teens so what i'm going to do is just use an appropriate bin width for the adults so we'd have just zero to nine first bin 10 to 19 for the second.
02:16
And i'm going to have to change how this is formatted so it doesn't automatically think it's a date.
02:22
So that should be 10 to 19.
02:24
No.
02:28
I don't want that format as a number.
02:30
That should be formatted as a as text.
02:36
There we go.
02:37
We have 10 to 19, 20 to 29, 30 to 39, 40 to 49, 50 to 59, 60 to 69, 70 to 79, 80 to 99, 809, and then theoretically, 100 to 109.
02:57
So then for the frequency, i'll say teen, freak, adult freak, is, to make the calculation easy here, what i'll do is add another column for the lower and upper values of each bin.
03:16
So we start at 0 and then go to 10 and so on.
03:21
It seemed to know what i want, or not...
