For your problem, it looks like maybe you want to find either a frequency distribution or a histogram for this.
00:10
And i know you want six classes.
00:15
So we have the lowest value is 45, is the low.
00:23
And we have our highest value is 109.
00:29
So if we take the difference between those and divide it by 6, let's see what that gives us.
00:37
So 109 minus 45 close that parentheses divided by 6 and that gives us 10 .6 repeating so let's have the class widths be approximately 11 now you could do something a little different from that and have it be probably to be 12 and still have six classes but i'm gonna have this class start at 45 and then then this next class will start at 56 this will start at 67 this will start at 78 this will start at 89 and then the last class will be up to 100 and one more oops one two three four five six and this one will be the last class and and so this will go from 45 up to 55.
01:33
This will go up to 66.
01:35
This will go up to 77, up to 88, up to 99.
01:41
And this one will go up to, and notice the trend.
01:46
We keep adding on 11.
01:47
And so this will go up to 110...
