How do categorical and quantitative variables differ?
Answer to relevant QuestionsHow do between-S versus within-S designs differ? Make up a list of names for imaginary participants, and use these names to show an example of between-S groups and within-S groups. Draw a sketch of the standard normal distribution. What characteristics does this function have? Under what circumstances will the value of SS equal 0? Can SS ever be negative? Why do we divide by (N -1) rather than N when we compute a variance from an SS term? What research decisions influence the magnitude of risk of Type I error? Suppose a researcher writes in a journal article that “the obtained p was p = .032; thus, there is only a 3.2% chance that the null hypothesis is correct.” Is this a correct or incorrect statement?
