1. PSYC08 Review Questions II
From a structural approach, an individual observation in and randomized-block design is viewed as being composed of what components? How do these components relate to the sums-of-squares ?
Let us assume that you have analyzed a data set both as one-way completely- randomized design and as a randomized block design. If all of the blocks had the same mean, how would the Fs from the two analyses compare? Why?
How are the three factors that determine power reflected in the formula for omega squared? Describe how the operate.
What information do you need to complete a repeated-measures analysis without the raw data?
Do the following data support the researchers hypothesis that the drugs differ with respect to hand-eye coordination? Analyze the data three different way: as a one-way completely randomized design, as a randomized-block design (each row is a block), and as a repeated-measures design (each row is a subject). Compare and discuss your results.
