摘要：Researchers in psychology using angular or cyclic data are faced with problems of periodicity and arbitrariness, associated with circular statistics, that render usual methods of parameter calculation useless. This introduction to circular statistics presents trigonometric functions used in the computation of circular parameters such as center of mass, concentration, dispersion and homeward component. Common circular distributions and circular statistical inference methods that may be useful in psychology are also described. An example of a simple orientation experiment illustrates the application of these statistical tests using Microsoft Excel.
