WebBivariate Correlation is a widely used term in statistics. In fact, it entered the English language in 1561, 200 years before most of the modern statistic tests were discovered. It is derived from the Latin word correlation, which means relation. Correlation generally describes the effect that two or more phenomena occur together and therefore ...

The hypothesis test for the slope β that we developed on the previous page was developed under the assumption that a response Y is a linear function of a nonrandom predictor x. This situation occurs when the researcher has complete control of the values of the variable x. For example, a researcher might be ... Webvariate tests and the bivariate tests. But imagine a situation where the origin lay in the region marked A on the plot. The point of the null hypothesis would lay outside the ellipse and so the bivariate test would reject while both univariate tests would reject. The situation would reverse for a null hypothesis in the region marked B.
