SCENARIO 11-10
A campus researcher wanted to investigate the factors that affect visitor travel time in a complex,multilevel building on campus.Specifically,he wanted to determine whether different building signs (building maps versus wall signage)affect the total amount of time visitors require to reach their destination and whether that time depends on whether the starting location is inside or outside the building.Three subjects were assigned to each of the combinations of signs and starting locations,and travel time in seconds from beginning to destination was recorded.An Excel output of the appropriate analysis is given below:
ANOVA

-Referring to Scenario 11-10,the within (error)degrees of freedom is
A)1
B)4
C)8
D)11

The within (error) degrees of freedom in an ANOVA context is calculated by subtracting the number of groups from the total number of observations. Without the specific details from Scenario 11-10, a typical approach would be N - k, where N is the total number of observations and k is the number of groups. Choice C (8) suggests a scenario where there might be a total of 11 observations across 3 groups (11 - 3 = 8), which is a common setup in ANOVA problems.
