Submit your solutions to the next questions utilizing the ANOVA supply desk under. The desk depicts a two-way ANOVA during which gender has two teams (female and male), marital standing has three teams (married, single by no means married, divorced), and the means discuss with happiness scores (n = 100):
• What’s/are the unbiased variable(s)? What’s/are the dependent variable(s)?
• What can be an applicable null speculation? Alternate speculation?
• What are the levels of freedom for 1) gender, 2) marital standing, three) interplay between gender and marital standing, and four) error or inside variance?
• Calculate the imply sq. for 1) gender, 2) marital standing, three) interplay between gender and marital standing, and four) error or inside variance.
• Calculate the F ratio for 1) gender, 2) marital standing, and three) interplay between gender and marital standing.
• Establish the crucial Fs at alpha = .05 for 1) gender, 2) marital standing, and three) interplay between gender and marital standing.
• If alpha is about at .05, what conclusions are you able to make?

Please Notice: The desk that you just see within the project has been barely modified from the one offered within the module notes since it’s past the scope of this unit to have college students calculate p values. As an alternative you might be requested to calculate the F worth and evaluate it to the crucial F worth to find out whether or not the take a look at is important or not
