Hypothesis Test for Correlation Coefficients Correlation coefficients have a hypothesis test. As with any hypothesis test, this test takes sample data and evaluates two mutually exclusive statements about the population from which the sample was drawn. For Pearson correlations, the two hypotheses are the following: Alternative hypothesis: H1: m1 - m2 ≠ 0 (strengths of the material from both companies are different) And that if the test's p-value is less than your chosen significance level, you should reject the null hypothesis.

argumentation. This logical relationship may be part of theoretical framework of the study. Correlational research is a type of non-experimental research in which the researcher measures two variables and assesses the statistical relationship (i.e., the correlation) between them with little or no effort to control extraneous variables. This needs to be tested with a hypothesis test — and known as the correlation test.

It is sometimes seen as the most rigorous and definitive part of a statistical analysis, but it is also the source of many statistical controversies. The currently-prevalent approach to hypothesis testing dates to developments that took place between 1925 and 1940 Alternate Hypothesis Ha: The population correlation coefficient is significantly different from zero. There is a significant linear relationship (correlation) between \(X_1\) and \(X_2\) in the population. Drawing a Conclusion There are two methods of making the decision concerning the hypothesis.
