A replication study dataset of the example from this chapter is given as follows (A = attractiveness, B = time; same levels). Using the scores from the individual cells of the model that follow, conduct a two-factor fixed-effects ANOVA (alpha = .05). Are the results different as compared to the original dataset?

The following training dataset is “reading email dataset”. This dataset has four features as follows: author, thread, length, and where to read the mail. According to the features the algorithm has to predict the user’s action whether to read or skip the mail. Use Naïve Bayes classifier to predict the user’s action (skips or reads) when the author of the mail is known, the thread of the mail is follow up, the length of the mail is short, and where...
