A Researcher at Michigan State University (MSU) Wanted to Determine

Short Answer

A researcher at Michigan State University (MSU) 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. A partial computer output of the appropriate analysis is given below: The degrees of freedom for the different building signs are ______________.
The degrees of freedom for the different starting location are ______________.
The degrees of freedom for the interaction between the levels of signs and starting location are ______________.
The error degrees of freedom are ______________.
The mean squares value for starting location is ______________.
The F test statistic for testing the main effect of types of signs is ______________.
The F test statistic for testing the interaction effect between the types of signs and the starting location is ______________.
In order to determine the critical value of the F ratio against which to test for differences between the levels of factor A, we should use numerator df = ______________, and denominator df = ______________.
In order to determine the critical value of the F ratio against which to test for differences between the levels of factor B, we should use numerator df = ______________, and denominator df = ______________.
In order to determine the critical value of the F ratio against which to test for interaction between levels of Factor A and levels of Factor B, we should use numerator df = ______________, and denominator of F = ______________.
