2) Which of the following is least powerful in terms of conclusions: Correlation, Quasi-experimental, or Experimental?
Homework Answers
Correlation is least powerful since it got affected by confounding variables
While for Quasi-experimental, or Experimental we design them with replication and manipulation to reduce variability from other sources.

1).Which type of research design (experimental or quasi-experimental) do you think is more likely to have higher validity? Why? 2).What type of methodology would you use to evaluate the effectiveness of a family preservation/child welfare intervention aimed at reducing the risk for future neglect or abuse in families referred for abuse or neglect?

Which of the following experimental data are consistent with the conclusions of Unwin and Henderson's experiments on transmembrane protein structure? A. Membranes undergo phase transitions that are determined by the molecular components of the membrane. B. Biological membranes are relatively fluid structures. C. Membrane phospholipids have more lateral and rotational freedom of movement than flip-flop movement between membrane leaflets. D. Many transmembrane proteins are characterized by one or more transmembrane alpha helices.

EXHIBIT 2 Fuzzy Quasi Is a Bear Quasi experiments are studies that are unable to use randomization to evaluate effectiveness of interventions. This can make it difficult to tease out possible confounders and assess the integrity of any cause and effect claims. Consider this example adapted from a paper in Clinical Infectious Diseoses A hospital wants to know if providing alcohol- based hand cleaners for staff will reduce the rate at which bacterial infections occur in the patient population. The...

(9 pts 3 pts each) For each of the following languages, name the least powerful type of machine that will accept it, and prove your answer. (Hint: a finite state automata is less powerful than a pushdown automata, which in turn is less powerful than a Turing Machine.) For example, to prove a language needs a PDA to accept it, you would use the Pumping Lemma to show it is not regular, and then build the PDA or CFG that...
