Answering Questions About Population Characteristics
This chapter describes how to use SPSS to test hypotheses about characteristics of a single population. SPSS for Windows has a procedure that computes the test statistic for a one-sample test only when the population standard deviation (σ) is unknown. When σ is known, you must compute the test statistic by hand, but you can use SPSS to find the sample mean, proportion, or median. This is especially useful when sample sizes are large and manual calculations are cumbersome.
