行为科学或生物科学的研究人员有大量的方法来研究不同群体之间差异的性质和统计意义。他可以使用各种各样的单变量方法来检验关于位置差异、分散度差异、属性对之间的相关性差异等的假设。在多变量情况下，可以使用各种方法来检验关于均值向量、方差-协方差矩阵、相关矩阵、因子结构等的假设。一种观点是描述性的，传统上在统计学中的估计主题下处理。另一个问题通常涉及是否合理的假设，一些假设模型的性质，人口之间的差异实际上是真实的，通常被视为根据假设检验。描述性的观点和推理性的观点必然经常重叠。
The researcher in behavioral or biological science has available a large arsenal of methods for studying the nature and statistical significance of differences between various groups of individuals. He may use any of a wide variety of univariate methods to test hypotheses about differences in location, in dispersion, in correlation between pairs of attributes, etc. In a multivariate situation methods are available to test hypotheses about mean vectors, variance-covariance matrices, correlation matrices, factor structures, etc.There are two points of view involved in studying the nature of differences between groups. One point of view is descriptive, and has traditionally been treated under the topic of estimation in statistics. The other usually involves a question as to whether it is reasonable to assume that some hypothesized model about the nature of differences between populations is in fact true, and has usually been treated under the ~pic of tests of hypotheses. The descriptive and inferential points of view must of necessity often overlap.
