| null hypothesis |
The assumption that nothing other than chance is operating to produce the effect which we see in a particular data set. The null hypothesis is rejected if a particular outcome, or the data set as a whole, is very unlikely to have been produced by chance. No particular alternative hypothesis is thereby proved; the only conclusion is that something is going on. See Lesson 1.
