Teaching the Effects of Additive and/or Multiplicative Constants on the Mean, Moments about the Mean, and Correlation.
Understanding the effects of additive and multiplicative constants on basic statistical procedures provides the important groundwork necessary for a thoughtful and logical understanding of more complex methods. This paper explores the effects of additive and multiplicative constants on the mean, standard deviation, skewness, kurtosis, and correlation. A constant is an operation consistently applied to all observations on a given variable. Small data sets and graphs are used to make the discussion more accessible and comprehensive. Additive and multiplicative constants have consistent and predictable effects on the mean, moments about the mean, and correlation. Three tables of data and seven graphs illustrate the analyses. Seven references are included. (Author/SLD)
