For a two-way ANOVA, a row factor has 3 different levels, a column factor has 4 different levels. The difference between the categories is not important. A two-way ANOVA test is a statistical analysis tool that determines the effect of two variables on an outcome, as well as testing how altering the variables will affect the outcome. There is a difference in average yield by fertilizer type. ANOVA is usually used when there are at least three groups since for two groups, the two-tailed pooled variance t-test and the right-tailed ANOVA test have the same result. A Tukey post-hoc test revealed significant pairwise differences between fertilizer mix 3 and fertilizer mix 1 (+ 0.59 bushels/acre under mix 3), between fertilizer mix 3 and fertilizer mix 2 (+ 0.42 bushels/acre under mix 2), and between planting density 2 and planting density 1 ( + 0.46 bushels/acre under density 2). Perceived control The internal consistency for the five-item measure was determined using the Cronbach alpha calculation (Cronbach, 1984). The table in the ANOVA F-test box shows the data for the F-test that test whether Factor 1 is significant, Factor 2 is significant and whether the interaction between Factor 1 and Factor 2 is significant. no interaction effect).
