frequency distribution in statistics, a mathematical function that describes the distribution of measurements on a scale for a specific population.
normal distribution a symmetrical distribution of scores with the majority concentrated around the mean; for example, that representing a large number of independent random events. It is in the shape of a bell-shaped curve. Called also gaussian distribution. See illustration.
 Normal distribution. The approximate percentage of the area (or frequency) lying under the curve between standard deviations is indicated. From Dorland's, 2000.
probability distribution a mathematical function that assigns to each measurable event in a sample group the probability that the event will occur.

frequency distribution

an arrangement of statistical data in order of the frequency of each size of the variable. For example, the numbers 2,3,5,3,4,2,1,3,4 would have the frequency distribution shown in Fig. 166. Data from a large sample often produces a NORMAL DISTRIBUTION CURVE.
