even I could not find much about few topics...

about SD I would suggest that just go through basic understanding of euqation and write few numbers and see how mean, SD and Median are behaving it will be helpful exercise..

I got this question from OG-11(PS-212)...

I 72,73,74,75,76
II 74,74,74,74,74
III 62,74,74,74,89

Arrange I,II and III data set in ordered from greatest Standard Deviation to least Standard Deviation..

I didn't really find any useful links, maybe you can try searching on Google

Just know the basics of SD, what it is, how it relates to the mean, the percentage distributions around the mean, beyond 1 SD, 2 SDs, etc. It also wouldn't hurt to know the formula on how to calculate SDs. I think its safe to say that only a normal bell-curved distribution will be tested.

For more on peccentage distribution, you can refer to my post here
