So for your problem, you have what is the class width for a frequency distribution with six classes? well, it's impossible to tell from this.
00:24
I'm going to give you a, for instance, if you have 30 is less than or equal to x, or you say that the class goes from writing it.
00:39
If you write it like this and say it goes up to 40, and this is 40 is less than or equal to x is less than 50, and 50 less than or equal to x is less than 60, and 60 less than or equal to x is less than 80.
00:59
80 less than or equal to x is less than 90.
01:02
You can see that i have one, two, three, four, five, six.
01:07
I have six classes here.
01:09
And you would have no way of knowing when i tell you i have six classes how wide they are.
01:16
This happens to be, and there are a couple different definitions, but if you take the difference between the lower, both lower limits, we would say 40 minus 30 would be 10, and we would say the class width, 10 is the class width...
