A consulting statistician and his client sat down together for the first time. Client: "I desparately need your help interpreting the significant three-way interaction in this factorial ANOVA. What are your fees?"
Statistician: "One hundred dollars for three questions."
Client: "Isn't that a little steep?"
Statistician: "Not really! Now what is your third question?"
*The client's third question was probably "Where is the door"? This is a sad situation where lack of two-way interation prevented the discussion of three-way interaction! Yes, I admit this one is all mine!
