On my assignment, its asking me to create frequency distribution table of the raw scores grouped by frequency. If its asking for raw data but the number set given has a range of 28-79 is it asking me to create table with 51 lines? How do you group by frequency vs grouping by class? What does it mean by raw data...

For reference, this is the question.

1. Prepare frequency distribution table of the raw scores* grouped according to frequency (f). Also show thecfand thec% columns. Forc% report up to 2decimal places. Don't roundup. (*Hint: show only the scores in the data set.)
