Document Summary

All we are doing is we are taking data from samples, and somehow we want to describe those numbers. To be able to take raw data and make some sense of it. We can put it in some orderly fashion. We are making a picture of the data and that picture can take on two formats - tables or graphs. 1. the set of categories that make up the original measurement scale. 2. the frequency (i. e. , # of individuals) in each category. Ungrouped categories table - used when range of scores is small (<10) Key thing is, if you look at the range of scores you have, if the range of scores is. Even if there is a number where there is 0 frequency, it still gets represented in the table, Common calculations relatively small (less than 10), then you would of ungrouped categories table. F represents frequency because it is in the range.
