WebAbout this unit. Analysis of variance, or ANOVA, is an approach to comparing data with multiple means across different groups, and allows us to see patterns and trends within complex and varied data. See three examples of ANOVA in action as you learn how it can be applied to more complex statistical analyses. WebNov 2, 2024 · To use these tables, decide whether the situation calls for a one-tailed or a two-tailed analysis and calculate Fexp. (Appendix 05.1) F exp = s A 2 s B 2. where sA2 is greater than sB2. Compare Fexp to F (0.05, ν num, ν denom) and reject the null hypothesis if Fexp > F (0.05, ν num, ν denom ). You may replace s with σ if you know the ...
