Sorry. Can't help you. I would if I could. I recently posted a question an received absolutely no help. Some people are utterly rude. Trust me, I would help you if I could.

anonymous · Answer

Yeah, I completely understand. :3

anonymous · Answer

The Data Set is 1 and 2, the mean is 4.3 and 4.9 and the mad is 1 and 1.2

phi · Answer

means-to-MAD ratio

do you know how to write a ratio as a fraction?
for example  ratio a to b  can be written as $\frac{a}{b} $

can you write the means to MAD ratio?

anonymous · Answer

Uh.. I don't think so. Could you walk me through it?

phi · Answer

write the ratio as a fraction.  first part of the ratio goes "up top", the second part of the ratio "goes below"

anonymous · Answer

So, it would be $$\frac{ 4 }{ 3 }  and \frac{ 1 }{ 1.2 }?$$

phi · Answer

they want the mean to mad ratio
what is the first part of that ratio?

phi · Answer

mean is the first part
for your first data set find the mean.  make that the top
find the second part of the ratio (the mad) .  make that the bottom
what do you get ?

anonymous · Answer

So.. 4.3 and 1?

phi · Answer

yes, but write it as a fraction.  first number (mean) goes up top, the other in the bottom

anonymous · Answer

$$\frac{ 4.3 }{ 1 }$$

anonymous · Answer

@phi

phi · Answer

yes, and that simplifies to 4.3 

now do the same thing for data set 2, and simplify

anonymous · Answer

$$\frac{ 4.9 }{ 1.2 }$$

phi · Answer

the "line" means divide.  for example 
$$ \frac{4}{2} = 2 $$

anonymous · Answer

4.08333333 is what I got dividing it.

anonymous · Answer

and 4.3

anonymous · Answer

So now what do I do?

phi · Answer

do you have answer choices?

phi · Answer

I have not seen this problem before.  Do you have notes on this ?

anonymous · Answer

Sadly, no.

phi · Answer

I need a definition of "means-to-MAD" ratio of 2 data sets.
I was assuming they wanted the two numbers you found 4.3 and 4.08

but if they want one number, we need to know what they are asking

phi · Answer

Your book must mention this.  can you post a copy of the section that talks about this?
