7: I nspect the frequency distribution carefully.

Has too much detail been lost? If so, reconstruct the table with a greater number of intervals (or use a smaller interval size). Is the table too detailed? If so, reconstruct the table with fewer intervals (or use wider intervals).

Are there too many intervals with no cases in them? If so, consider using open-ended intervals or intervals of unequal size. Remember that the frequency distribution results from a number of decisions you make in a rather arbitrary manner. If the appearance of the table seems less than optimal given the purpose of the research, redo the table until you are satisfied that you have struck the best balance between detail and conciseness.
