Document Summary

Raw score is data point that has not yet been transformed or analyzed. Frequency distribution describes the pattern of a set of numbers by displaying a count or proportion for each possible value of a variable. Researchers are usually most interested in the relations between two or more variables. Frequency table is a visual depiction of data that shows how often each value occurred; that is how many scores were at each value. Values are listed in one column, and the numbers of individuals with scores at that value listed in the second column. Include all values in the range even those for which the frequency is 0: count the number of scores at each value, and write those numbers in the frequency column. Group frequency table allows researchers to depict data visually by reporting the frequencies within a given interval rather than the frequencies for a specific value.
