You are the MAN :)

@acer 

Thanks for the reply. What you have looks exactly like what I want:)

But there is a small problem. When i copy your code, or even when i open the file you attached and run it, it looks different from some reason. I am using Maple 2016, not sure if that makes a difference?

@tomleslie 

Thank you.

I just think Method 4 should be the default since these are the answers that you would get with any calculator, software, or even by hand using the common stats formulas.

@Carl Love 

Any stats textbook in the world would give you 2.5 as Q1 and 6.5 as Q3 so I don't get how the default setting for just going Quartile(List,1) would not give you 2.5.  

Even using a simple scientific calculator, let alone Ti-83/84 or Minitab would give you the right answers right away.

I have been using Maple for many years for Pre-Calc and Calculus and it was very strong and didn't have many issues. Recently started using it for Stats and already running into problems.

 

@Kitonum 

Q1 should be 2.5

Q2 (which is the median) should be 4.5, which is close enough to what Maple gives

Q3 should be 6.5

Q1 and Q3 are far off

@Thomas Richard 

It's Maple 2016

Attached is the exact situation.

Here is the text as well:

L := [1, 2, 3, 4, 5, 6, 7, 8];

with(Statistics); Quartile(L, 1);

Answer should be 2.5 but Maple is giving 2.4166666666

@Kitonum 

 

Thank you perfect. Exactly what I needed:)

@Kitonum 

 

Thanks for the help. This actually solves most of the problem but not the entire problem. These quotations won't really work if the value under the square root is a calculated value and not just a set value such as a 4 or a 9.

a:=3: b:=5: sqrt(a-b);

How can I make this actually display the square root of -2. It keeps giving me I then sqrt of 2.

Using all the quotation suggestions you gave me won't work either becuase it will actually give a and b there not the -2.

@acer 

 

Will give this a try thanks:)
