| 一般注記 | License restrictions may limit access This work introduces difference of means t-tests. This method allows researchers to compare the means of a single variable for two subsets of the data to evaluate whether the means for those two subsets are statistically significantly different from each other or not. This technique builds on the single mean t-test. This example describes the difference of means t-test, discusses the assumptions underlying it, and shows how to compute and interpret it. There are many variants of difference of means testing - this example focuses on the independent samples t-test. We illustrate this using a subset of data derived from the 2007 British Crime Survey. Specifically, we test whether people who live in rural areas have a different level of confidence in the police compared to those that live in urban areas Specialized Description based on online resource; title from home page (viewed on May 18, 2015) |
