So for this problem, the first thing that we want to do is actually set up our frequency chart or frequency table for the data.
00:09
We'll use that to then create the histogram.
00:11
So we'll have our different bins, or the different ranges you could call them.
00:16
We know that the first interval is dictated to us to be from 10 to 19.
00:23
Presumably we'll want an integer difference between maximum and minimum value for each bin.
00:29
So the first bin is 10 to 19, the second will be 20 to 29, third will be 30 to 39, and...
00:41
Okay, pardon me.
00:43
Fourth will be 40 to 49, and i'm just looking at the data that we have here.
00:48
It does not look like we have any values greater than 49.
00:51
So we'll just go for a histogram with four bins, since it doesn't specify how many bins we want to have.
00:57
And then we just need to count the frequency.
01:00
Now i'll pause while i do this.
01:02
Alright, so as you can see, what i did was i went through and created a tally just reading through the data points from left to right.
01:08
So we have that our frequencies are going to be 3, 11, 5, and 3.
01:16
And now to create our histogram, what we'll do.....
