Frequency Tables?

[JayGarrick]

Hey.I'm currently revising Frequency Tables as part of the GCSE Higher tier Mathematics. I was wondering if you could provide some information regarding the frequency tables including the usage of mode, median, mean and range. Also i was wondering i you could please provide a few websites which explain this as well.Thanks so much. All comments are very much appreciated. Thank You.
