Running head: OBSERVATIONAL EXPERIMENTS Observational Experiments Name Institution 1 OBSERVATIONAL EXPERIMENTS 2 Observational Experiments Observational experiments are studies whereby the researchers collect data on the basis of what is heard and seen on the field. An example of such a study is a research experiment where the effects of sports on academic performance are sought. In that study, the researcher conducts a survey of the different sports that the students play and their GPA. In this observational study, the independent variables are the different types of sports played on campus while the dependent variable is the GPA for each student. Other than the independent and dependent variables, other factors that may affect this observable study include the hours dedicated to classwork and also the IQ of the students. The number of levels of the factors included is equal to th ...

Medical professionals can find relationships between variables. The more you drink alcohol, the less functionality of your liver. The less carbohydrates a person intakes, the lower their Body Mass Index.Data can be collected and organized as an ordered pair (x, y). The data can be analyzed to determine the type and strength of a correlation and to calculate a regression line in order to make a prediction.Use the internet to find a data set of ordered pairs.

GMU Wk4 EB Metabolic Syndrome Prevention & Treatment Program Article Discussion

Implementing an Evidence-Based Metabolic Syndrome Prevention and Treatment Program Utilizing Group VisitsIn this study, the researchers looked at changes in patients understanding of risk factors associated with metabolic disease and changes in habits to decrease those risks. Through a model curriculum, participants were provided information about how their decisions were influencing the development and progression of metabolic disease. .This is an interesting study because here we see the use of both repeated measures t-tests as well as independent t-tests. How did the researchers use both types of t-tests in light of the fact that we discussed you should choose one or the other?Discuss the sample size in the Sumter County sample. Using a a source, discuss the validity of the design with just 5 participants? In the article, the authors indicate that some data are positively-skewed. Discuss the meaning of that, and why would the skew of data interfere with using it in the t-tests? (In your response, consider the distribution of the test statistic). Hospital Rates of People Living with HIV in the United States, 2009 The authors use confidence intervals (CI) throughout their results.Using an example from the article, explain the meaning of the CI for the specific case you selected.How could you decrease the range of a confidence interval?Review Figure 1 carefully. Notice that the CI is given as whiskers on the plot. Using the data in the text about this figure and the overlapping nature of the confidence intervals and the means, explain why there is a significant difference between Black and White but not White and Hispanic.In Table 2 the authors present data surrounding the hospitalization rates based on sex both by OIs (preventable and non-preventable).Research the rate ratio and discuss it for the preventable OIs data.Construct an appropriate graphical representation of the data in Table 2
