www.math.utah.eduto graphically summarize data: frequency distributions, frequency histograms, and a cumulative frequency graph. 1 Frequency distribution A frequency distribution is a table that shows \classes" or \intervals" of data entries with a count of the number of entries in each class. The frequency f of a class is the number of data entries in the class.

RESEARCH METHODS 1: FREQUENCY DISTRIBUTIONS
users.sussex.ac.ukHow can we compare frequency distributions when they are based on different totals? The solution is to turn our "raw" frequencies into relative frequencies. To turn a raw frequency into a relative frequency, divide the raw frequency by the total number of cases, and then multiply by 100. Thus (25/50)*100 = 50%, and (25/100)*100 = 25%.

INTRODUCTION TO FREQUENCY DISTRIBUTION
math-stat.netGROUPED FREQUENCY DISTRIBUTION TABLES There are some rules that we should take into consideration in the construction of a grouped frequency distribution table: 1) It should have about 10 class intervals. 2) The width of each interval should be a relatively simple number. For instance, 2,5,10, or 20 would be a good
