Statistics: 1 : a branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data
2: a collection of quantitative data
Other terms used in discussing and using statistics:
variance : expressed as standard deviation, represents the average distance of each score from the mean
frequency distribution : commonness of the values of a variable (how often it occurs in the data set)
dispersion: the scattering of the values of a frequency distribution from the mean
range : difference between the least and greatest values of the variable of a frequency distribution
The Normal Distribution Empirical Rule
*Provides an estimation of the spread of data given the mean and standard deviation of a data set that follows the standard, normal distribution
