Question

Consider the resulting table for a Two-Factor ANOVA with replication regarding standardized final exam scores for twelve students from three universities: six day students (two from each university), and six night students (two from each university): a. At alpha = 0.05, do the universities prepare students at different average levels of capability based on these scores? Circle one YES NO b. At alpha = 0.05, is there a difference in average levels of performance between day and night students based on these scores? Circle one YES NO c. At alpha = 0.05, do the universities prepare day and night students at different average levels of capability based on these scores? Circle one YES NO

Explanation / Answer

a) Yes

look at the first row of the table (university)

Fcritical > Ftable

thus we can reject the null hypothesis and clude that yes universities prepare students at different average level of capability based on these scores.

b) No

look at the 2nd row of day and night students

Fcritical < Ftable

you can not reject the null hypothesis

thus level of performane of day students = level of performance of night students

c) No

look at the the third row of interaction

Fcritical< Ftable

You can not reject the null hypothesis

thus universities do not prepare day and night students at different average level of capability.
