WebUnivariate statistical tests are those tests that involve one dependent variable. Examples include t-tests of means, analysis of variance (ANOVA), analysis of covariance, linear regression, and generalized linear models such as binary logistic regression. In all of these cases, there is only one dependent variable. Web15 iun. 2024 · The two hypotheses for this particular two sample t-test are as follows: H0: µ1 = µ2 (the mean weight between the two species is equal) HA: µ1 ≠ µ2 (the mean weight between the two species is not equal) Since the p-value of the test (0.0463) is less than .05, we reject the null hypothesis. WebIn statistics, multivariate analysis of variance (MANOVA) is a procedure for comparing multivariate sample means. As a multivariate procedure, it is used when there are two or more dependent variables, and is often followed by significance tests involving individual dependent variables separately..
