1. 40 OT students were randomized into two groups and 40 nursing students were randomized into two groups. One of the OT groups and one of the nursing groups were given the opportunity to participate in a research project and present their data at an IPE conference. The other group of OT students and nursing students completed their normal course work. At the end of the semester the faculty measured all of their students’ knowledge about research design and confidence presenting information to others. (a) Independent Variable(s): (b) Dependent Variables(s): (c) Research Design: 2. 60 participants with a diagnosis of bulbar type ALS were divided into two groups to work with SLP either 3 times a week for 1 hour or 6 times a week for 2 hours. At the end of the study, all participants completed an assessment of speech quality and swallowing ability. (a) Independent Variable(s): (b) Dependent Variables(s): (c) Research Design:
The α level in the context of reporting findings from a randomized controlled trial corresponds to the probability of concluding: Correctly that the treatment and control groups differ with respect to risk of outcome. That the treatment and control groups differ with respect to outcome when in fact they do not. Correctly that the treatment and control groups do not differ with respect to outcome. That the treatment and control groups do not differ with respect to outcome when in fact they do. That you don’t have sufficient information to present results.

In order to investigate the relationship between dietary aflatoxins and hepatocellular carcinoma (HCC), all cases of liver cancer developed in the past five years and liver cancer-free controls selected from a pre-existing study cohort at the time of diagnosis were included in the analysis. The exposure of interest, aflatoxins, was assessed from dietary recall questionnaires collected from the subjects at the beginning of the study Describe the study as to its particular sampling method.

Out of these associations between a potential exposure (risk factor) and an outcome (health condition or disease), identify the one that is most likely to be causal based on the "strength" of the association. Assume that you no nothing else about the factors and/or the outcomes. Please note: the values of some associations are hypothetical/imaginary, the associations are plausible a. A number of chemicals in tobacco products have been shown to induce cancers in laboratory settings b. Men employed in occupations requiring them to sweep chimneys with tars and/or mineral oils have been shown to have 200 times risk of dying from scrotal cancer compared with men not engaged in such occupations. c.

Oxycontin is a drug used to treat pain, but it is well known for its addictiveness and danger. In a clinical trial, among randomly selected subjects treated with OxyContin, 52 developed nausea and 175 did not develop nausea. Among other randomly selected subjects given placebos, 5 developed nausea and 40 did not develop nausea. Use a 0.05 significance level to test the claim that the proportion of nausea is different for those on OxyContin than for those who are on placebo. Use the critical value method. Include a diagram of the distribution indicating important components of the question.

Identify the variables (dependent/independent), and research design type (correlation/experimental) for the following studies: Septe 5 a) A study recruits participants and measures their levels of physical activity and self- reported stress levels. b) A research project investigates the impact of a new workout program on participants' body mass index (BMI). Participants are randomly assigned to either the new program or a control group. c) Researchers observe a group of individuals engaging in different types of exercise routines and examine their reported levels of happiness.
