Grade Frequency

A 2

B 8

C 11

D 2

F 1

I think that the grades would double if there was twice as many. Thanks.

**bobpursley**, Wednesday, July 29, 2009 at 9:29pmYou are wrong. You didn't answer the frequency part.

What is the difference between 2/15 and 4/30?

**B.B.**, Wednesday, July 29, 2009 at 9:58pmThe difference between 2/15 and 4/30 is .133333333. Where did you come up with 2/15 and 4/30? I'm confused now.

Consider that if there were twice as many of each grade, the total would be twice as great, but so would the number of grades. So the average would be the same.

**B.B.**, Thursday, July 30, 2009 at 2:28pmIs this answer correct? Just double each number. The "frequency" establishes a percentage breakdown ( unless something else changes ) would stay the same no matter how many grades there are. With every grade doubling, the percentage breakdown stays the same.
