In this article, it talks about cholera outbreaks in Vietnam again. Cholera is contagious that causes diarrhea. It often happens in poor and high populated counties that have a difficult time getting safe to drink water such as Vietnam. From 1979 to 1996, there was high amount of people in Vietnam with cholera. In 1997 there was vaccination for it so the amount decreased, however in 2006 the amount of people affected increased again. The cause was linked to food and unsanitized water from the river-

Article One Okun (2012) utilized a systematic review of four samples to explore deep brain stimulation effects on advanced Parkinson’s patients’ quality of life, severity of motor symptoms, and the number of hours per day spent in the “on” state without dyskinesia (Appendix D). Pertinent findings from the critical appraisal of this article included: validity of the reviews utilized in the study, sample size, measurement of variables, findings, and strengths and weaknesses. The review employed four

Describe some of the important research designs used in experimental hypothesis testing research study. Research design is needed because it facilitates the smooth sailing of the various research operations, thereby making research as efficient as possible yielding maximal information with minimal expenditure of effort, time and money. Different research designs can be conveniently described if we categorize them as:(1) Research design in case of exploratory research studies;(2) Research design

attitudes towards teamwork across a surgical provision. The intervention was based on Crew Resource Management (CRM), which uses participatory action research to familiarize the strategies within the specific team context. A longitudinal quasi-experimental design was

Identification of Articles Through my search for articles I discovered that there were no studies of randomized controlled trials, and there were therefore no systematic reviews or Meta analyses of randomized controlled trials related to my topic question. This limited the variety and amount of studies that could be utilized to help answer my question. I found a variety of observational studies that addressed melanoma screening that did not address my exact question I was trying to address.

Optimization of medium composition and culture conditions Experimental design Selection of significant variables by Plackett-Burman design The screening of significant variables influencing biomass production of Chaetoceros muelleri was accomplished by Plackett-Burman experimental design using the statistical software Design Expert (version 6.0.9, Stat-Ease Inc, Minneapolis, MN). Three nutritional parameters (nitrate

Part A What is the Null Hypothesis (Ho)? There is no difference in mean WAVFT score between student who did not take the language arts program and the students who did. What is the Alternative Hypothesis? There is a difference in mean WAVFT score between students who did not take the language art program and the students who did. What is (are) the Independent Variable(s)? The independent variable of this study is the language arts program. There are two levels: students who did take the language

Both control and experimental group are used in an experiment, however the experimental group will not be exposed to the IV but the control group will be. 2. Fully explain (2-4 paragraphs) the concept of comparison of control and experimental group. To conclude if a treatment had effect, a research will compare the experimental group to the control group. In a controlled experiment there are two or more things being compared. However, there is only one variable (IV) that will be changed, meaning

Assessment #3 To investigate the dangers of texting while driving, a true experiment is needed to determine if texting is a cause of traffic accidents. A true experiment is thought to be the most accurate type of experimental research, and it is the only type that can establish a cause and effect relationship. Thus, a true experiment can find if texting is a cause that affects traffic accidents. To begin, the experiment will take place on a major road, located in an urban city because a large number

to adopt the correct analytical method to measure their outcomes which affect their external validity, four studies have been chosen each addressing different treatments using single or combination of drugs for analysis in their methodology and experimental design . A randomized double blind study by (Ciodaro et al,. 2014) has been chosen to illustrate
