    working out the range?

    Hi, this is my question:

    The height,s, of 50 sage seedlings is measured.
    The table summarises the results.

    working out the range?-zzz.jpg


    A) draw a histogram to represent the height of the sage seedlings.
    I HAVE DONE THIS!

    B) calculate the MINIMUM possible range for the heights of the sage seedlings.

    how would i do part B)? would it be 12-1=11?

    thanks for you help!
