There is no difference in average yield at either planting density. In the ANOVA table, the regression consists of two rows, namely regression/model as row 1 and residual/error as row 2. The critical ingredient for a one-factor, between-subjects ANOVA, is that you have one independent variable, with at least two Part 2: Confirm JAMOVIs conclusions by conducting the same ANOVA manually. The one-way, or one-factor, ANOVA test for independent measures is designed to compare the means of three or more independent samples (treatments) simultaneously. The blue lines split the graph in the acceptance and rejection region, using 90%, 95% and 99% confidence level. The F test is a groupwise comparison test, which means it compares the variance in each group mean to the overall variance in the dependent variable. pH 7 pH 9 1 0.079 0.052 2 Next, we will fill in the ANCOVA table.
