Exercise 3 in Module 20 examined whether adding a fragrance to a window cleaner led people to believe that it cleans better than unscented product.  There were 12 subjects in each group: scented or unscented.  The mean cleaning effectiveness rating for the group getting the scented cleaner was 7.42. The meaning cleaning effectiveness rating for the group getting unscented was 6.00.  The standard deviation for cleaning effectiveness ratings across all subjects is 1.369.

scented cleaners =7.42+/-1.369

=8.789/6.051

uncented cleaners=6+/-1.369

This is the rest of the question sorry! Please Help!!!

Exercise 3 in Module 20 examined whether adding a fragrance to a window cleaner led people to believe that it cleans better than unscented product.  There were 12 subjects in each group: scented or unscented.  The mean cleaning effectiveness rating for the group getting the scented cleaner was 7.42. The meaning cleaning effectiveness rating for the group getting unscented was 6.00.  The standard deviation for cleaning effectiveness ratings across all subjects is 1.369. A t test showed that the scented cleaner was rated as a significantly more effective cleaner (t=2.84, ᵅ<.01).

    1. Calculate the effect size for this study, using both Cohen’s d and effect size r.
    2. Interpret the result: Was there a practical difference in cleaning effectiveness between scented and unscented cleaners?
