Question 2

We have three price points and three product colors and we have randomly assigned combinations of price points and colors to focus groups who have rated them on how likely they would be to purchase them. What is the simplest test we could use to see if there is any impact of price point, color, or the interaction?

Question 11

10 pts

Please explain the assumption of sphericity? What's the consequence if we violate the assumption?

Answer 1

1.

2.

IF the colours are c1,c2,c3 and the prices are p1,p2,p3 then the table would look like

	c1	c2	c3
p1
p2
p3

since there are two factors(price & colors) the answer shall be two-way factorial ANOVA

3. The question is not clear . However , there is a single factor (condition) and since there is more than 1 levels(3 conditions) , one-way ANOVA with blocking is likely to be the answer.

4. The outcome variable is a dichotomous variable(2 categories:- married/single) . with categorical(major, economic status,) & continuous (age) variables. In such scenarios logistic regression is best for prediction/classification.

5. Assuming purchase ability is a categorical variable , and economic status is also continuous the most appropriate answer would be Logistic regression.

6.economic status = continuous variable(explanatory ) & salary = continuous (predicted variable) ,the most appropriate answer would be Multiple  regression.
