    class limits and boundaries

    Hi;
    I not quite sure when I shoud be dealing with limits or boundaries?
    My data is sorted as follows.


    class limits and boundaries-data.jpg







    Now I'm thing the data should be graphed using class boundaries
    because this creates no gaps is this correct?

    also I the data had no gaps ie 50-60,60-70,70-80... are class limits and boundaries the same
    therefore I would graph using limits is this correct?

    essentially if there's gaps create boundaries and no gaps use limits(which themselves are the boundaries)?
    Thanks.

    Hey anthonye.

    I think you should read up more on what is called "continuity correction". It might answer your questions (and others you may have yet to ask):
