Tell me something about sets, man!! I can answer the easy ones like A 'union' B or A 'intersection' B, but the long ones like (A 'union' B)/ 'intersection' C gets outta control!! Even better, do u know about any good notes about sets that I could download?

All you need to know is the basics. In the long ones, work it out step by step.

Wait a minute. That's odd. None of the 2010 P4 have sets questions. Didn't P4's have questions about sets?

Also, can anyone make me understand scatter diagrams and correlation. Thank you in advance!

Re: Maths made easy =) stuck sumwhere?Ask ur doubts here!!

For 3 c (ii), u find the sum of the row "Time Taken in Minutes" and divide the answer (71) by the number of digits or elements (12).
For 3 d (i), you have to see which is the most occuring number in the "Number of correct answers" row (26).
For 3 d (ii), you have to arrange the "Number of correct answers" row from smallest to greatest, and find the number in the middle. If you end up with 2 numbers in the middle, you have to find their average. (add them and divide by 2)

Correlation is a measurement of how strong the relation there is b/w two sets of data.
There are different kinds of correlation. The attached picture may help you!
