say my data set is [1,2,5,3,6,2,2,4,5,2,2,3,1,8]

First of all you have to sort the numbers into order

10 March 2011

how do I do that?

10 March 2011

[1,2,5,3,6,2,2,4,5,2,2,3,1,8].sort

10 March 2011

[1, 1, 2, 2, 2, 2, 2, 3, 3, 4, 5, 5, 6, 8]

10 March 2011

then what?

10 March 2011

?

10 March 2011

Then you need to find the middle value

10 March 2011

using a ruler?

10 March 2011

so you have 14 values

10 March 2011

take the middle 2 values number 7 and 8

10 March 2011

so that is values 3 and 4

10 March 2011

so $ frac{3 + 4}{2} = 3.5$

10 March 2011

so is the median 3 and 4 or 3.5?

10 March 2011

You've got it!

10 March 2011

Sorry, its 3.5

10 March 2011

Hoping that someone can give me a bit more guidance on this topic...

Hi, basically, you arrange your numbers in order and then pick the middle one. That's called the median. I you have an even number of numbers, though, like in your example, then there are 2 in the middle, so find the number half-way between them.

Sorry, 3rd sentence should have been "If" at the start, not "I".
