    This is the calculator I have, is there any way which it could calculate standard deviation without me doing each part bit by bit? I have read the manual and I cant find anything. It works out the variance I think(which I forgotten how it relates to standard deviation) and it can tell me the mean. All I need it to do is work out SD, i'm sure it does this somehow. Any idea's?

    Thanks in advance

    Standard Deviation is just the square root of the variance.
    I have the same calculator But you should always show your working in exams to gain method marks
