  1. Statistical hypothesis testing - Wikipedia


    Variations and sub-classes. Statistical hypothesis testing is a key technique of both frequentist inference and Bayesian inference, although the two types of inference have notable differences.Statistical hypothesis tests define a procedure that controls (fixes) the probability of incorrectly deciding that a default position (null hypothesis) is incorrect.

  2. Hypothesis testing - Handbook of Biological Statistics


    Summary. One of the main goals of statistical hypothesis testing is to estimate the P value, which is the probability of obtaining the observed results, or something more extreme, if the null hypothesis were true. If the observed results are unlikely under the null hypothesis, your reject the null hypothesis.

  8. Null hypothesis - Wikipedia


    In inferential statistics, the null hypothesis is a general statement or default position that there is no relationship between two measured phenomena, or no association among groups. Testing (accepting, approving, rejecting, or disproving) the null hypothesis—and thus concluding that there are or are not grounds for believing that there is a relationship between two phenomena (e.g. that a ...

  9. Test regression slope | Real Statistics Using Excel


    In this section we test the value of the slope of the regression line. Observation: By Theorem 1 of One Sample Hypothesis Testing for Correlation, under certain conditions, the test statistic t has the property. But by Property 1 of Method of Least Squares. and by Definition 3 of Regression Analysis and Property 4 of Regression Analysis. Putting these elements together we get that
