    Standard Deviation

    I just started stats, and im kind of confused about SD. I know how to find it, but dont really understand what, for example, SD of 2.5 means.
    Can someone explain?

    Heres an example of a question I dont understand.
    Is the SD of the number of years of college professors teaching experience:
    6 months
    6 years
    16 years

    Can someone tell me and explain why...in easy terms?
    Id really appreciate it!

    The standard deviation is how far away the result is from the mean.
