Researchers often use factorial designs because _____.

		they allow us to see the interaction of factors
		they more closely approximate the real-world
		both a and b
		none of the above

Expert Solution

A factorial design allows the researcher to study the effect of each independent variable on each dependent variable as well as the effects of interactions between the independent variables on the dependent variable

Factorial designs can test limits; to test whether an independent variable effects different kinds of people, or people in different situations, the same way.

Factorial designs are more efficient than OFAT experiments. They provide more information at similar or lower cost. They can find optimal conditions faster than OFAT experiments. Factorial designs allow additional factors to be examined at no additional cost.

Hence both a and b

Scatter diagrams allow us to see relationships between two variables. Cite an example of two variables that might have a strong positive relationship. What would that scatter diagram look like? Next, cite an example of two variables that have very little relationship and describe what that scatter diagram would look like. Last, tell us why illustrating data in this way is helpful. Can this be typed out? It's for a discussion board.

Often it is impossible to use experimental research designs in Political Science, as many political variables would be impossible to randomize (ideology, regime, etc.). How can we then test casual hypotheses if we don’t assign treatment and control like we’d do in an experimental setting?

Investigators who us nonrandomized controls in clinical trials often argue that their controls are satisfactory because the distribution of prognostic factors in the control and experimental groups is similar before therapy. It is better to randomize because A placebo effect s easier to detect in randomized trials Randomization tends to magnify the differences between placebo and treatment groups Many important prognostic factors that were not considered may lead to bias It is easier to maintain blinding in randomized trails Compliance...

1. Pain often goes unrecognized and untreated because it is patient subjective. ● What factors influence a patient’s response to pain? ● What is the difference between the subjective and objective data?

11. One reform idea that is often floated in the US is the use of Medical Savings Accounts (MSA’s) in conjunction with high-deductible insurance plans (sometimes called catastrophic coverage). Individuals could deposit pre-tax dollars into their MSA and use the money to pay for out-of-pocket medical expenses. If unused, the MSA money simply becomes savings for the individual. 1. What is a high-deductible plan? 2. What are the pros and cons of such a plan?

7.48 The Graded Naming Test and sociocultural differences: Researchers often use z tests to compare their samples to known population norms. The Graded Naming Test (GNT) asks respondents to name objects in a set of 30 black-and-white drawings. The test, often used to detect brain damage, starts with easy words like kangaroo and gets progressively more difficult, ending with words like sextant. The GNT population norm for adults in England is 20.4. Roberts (2003) wondered whether a sample of Canadian...
