    It will depend on whether the data you use is grouped or not.

    A frequency table is basically a table for the display of data. There is a heading for the range of the data, and a frequency column (hence the name frequency table) which gives the number of occurrences of each set of data.

    Take this example:


    This frequency table shows the number of leaves of each colour which fell during an hour in autumn. 5 means that 5 red leaves fell.

    Now this table is one where you have distinct data. What about...



    Here you have grouped data, meaning you lost details. You have 5 apples with a mass between 450 and 460 g, but you don't know their exact mass.

    Can you now think of an advantage? :)
