Frequency (statistics)
A frequency distribution is said to be skewed when its mean and median are significantly different, or more generally when it is asymmetric. The kurtosis of a frequency distribution is a measure of the

4.2: Frequency Distributions and Statistical Graphs
Frequency is the number of times a data value or groups of data values (called classes) occur in a data set. A frequency distribution is a listing of each data value or class of data values

Managing and operating on frequency tabulated data is much simpler than operation on raw data. There are simple algorithms to calculate median, mean, standard deviation etc. from these tables. Statistical hypothesis testing is founded on the assessment of differences and similarities between frequency distributions. This assessment involves measures of central tendency or averages, such as the mean and median, and measures of variability or statistical dispersion, such as the standard deviation or

When you obtain the exact frequency for each score in a population, you can construct frequency distribution graphs that are essentially the same as histograms, polygons, and bar graphs that are
Shapes of Distributions
When graphed, the data in a set is arranged to show how the points are distributed throughout the set. These distributions show the spread (dispersion, variability, scatter) of the data. The spread may be
