How do they show symmetry? This is symetry:absolution* said:hah, such a stupid question...
what did you guys say for 2 f)
i said there is little symmetry but im having trouble getting my graphs to accurately show that..
-------------||||-------------
its equal on all sides the graphs are different. The mean, mode etc arent equal either.

Big question!!:
WHAT THE HELL IS WITH THIS QUADRANTS CRAP!
The formula in the lecture notes is
Q1=1(n+1)
--------
4
So, how come when you work it out manually, you get a different answer from excel?
i.e. 1(20+1)
---------- = 5.25
4
So, this would mean the 5.25th term in the sequency is the value for Q1.
So, I gather to work out Q1 and the 5.25th term, we have to do the following:
(6th term - 5th term)
---------------------------- = x
4
then we add x to the 10th term.
So, in the case of the question we do the following:
(0.97-0.93)
-------------- = .04/4 = 0.01
4
Then we add x to the .93 term = 0.94
Yet in excel the answer is the following when i type in the formula:
=QUARTILE(A1:A20),1
The answer here is:
0.96
AHHHHHH! WHERE DOES THE 0.96 come from????
