All right, so let's take a look here at this problem that gives us some information with some numbers here.
00:07
One of the first things we can do in order to make our lives a little easier for this is we can identify some key features that will help us in creating not only our distribution, frequency distribution, but also then creating our histogram.
00:22
So here we can see that our minimum value is going to be 35, our maximum value is going to be 45, and then, if we actually subtract our maximum from our minimum, we will get a range of 10.
00:36
They've told us that they want us to develop something with the class width of one.
00:41
And so since we have a range of 10, that means that we're going to have 10 individual classes, which will allow us to then construct our histogram.
00:50
I want to look here first at this frequency table that is here.
00:55
What's nice about the frequency table is that what i ended up doing was looking at all of those values that they gave us, and then ordering them.
01:03
So you can see that i started with 35, which is our minimum.
01:07
And then i went all the way to 45.
01:10
What was also nice is that because we know that this is a class width of one, we know that there's going to be an increment of one in between each of our x values.
01:18
So it'll go 35, 36, 37, and so forth.
01:23
Then i just counted the number that each individual value appeared in that list of numbers.
01:29
And so it's always a nice thing.
01:31
Thing to go through and then make some tally marks...
