Draw a table with three columns. Label the first column as Data Range, the second column as Hash Marks and the third column as Relative Frequency Distribution.. Write your data ranges in the data range column. Make sure these do not overlap. Sort through your data set and make a hash mark in the Hash Mark column each time the data falls within a proper data range.
