    Background Information
    The script was originally designed to help teachers analyse their student marks.
    Many teachers keep marks in spreadsheets, but don't have the time or expertise to insert formulas to perform all the statistical calculations.
    Statistical calculator allows users to simply copy and paste their data, then calculate and print the statistics.
    It is useful, particulary for moderation purposes where many teachers teach the same subject across a year level & for feedback purposes to students and parents.
