For each of the studies in #1 through #4, answer the following questions a) What is the response variable? b What is the study unit? d) e) What are the factor(s)? For each factor, give the corresponding factor levels. If it is a multi-factor study, list the treatments. Is the study experimental, observational or mixed? Why? Explain in terms of the factors.Four methods for teaching sign language are to be compared. 16 students majoring in special education and 16 students majoring in other areas are randomly chosen. Within each group, 4 students are randomly assigned to each of the 4 sign language teaching methods. Average scores on a final exam are to be compared. 3. A grain dryer is to be tested to determine the effects of voltage in the electric circuit and fan speed on the drying time. 2 voltages and 3 fan speeds were decided on,. 30 batches of grain (of the same type, weight, volume) are available for the study. 5 batches are randomly assigned to each voltage- speed combination. 4.
