While a frequency distribution gives the exact frequency or the number of times a data point occurs, a probability distribution gives the probability of occurrence of the given data point when the number of test cases are large, the frequency distribution and the probability distributions are similar in shape. Frequency distribution definition is - an arrangement of statistical data that exhibits the frequency of the occurrence of the values of a variable an arrangement of statistical data that exhibits the frequency of the occurrence of the values of a variable. A cumulative frequency distribution is a way to list how many values fit into the first class, the first 2 classes, the first 3 classes, etc, or the last class, the last 2 classes, etc here's a cumulative less than frequency distribution for the above set of data. The vertical axis the cumulative frequency or relative cumulative frequency the horizontal axis is the class boundaries the graph always starts at zero at the lowest class boundary and will end up at the total frequency (for a cumulative frequency) or 100 (for a relative cumulative frequency.
