Analysis Techniques: Correlation
A positive correlation between annual income and amount spent on car would be expected. This means that there is a relationship between the two and that, in general, higher annual income would show an increase in the amount spent on car, while lower annual income would show a decrease in the amount spent on car.
However, it would not be expected that this would be a strong relationship because other factors would influence the amount spent on car. For example, some individuals with an income in the middle range may consider an expensive car a key priority, while others would have other priorities. In addition, annual income level is not a true measure of wealth because...
Then values of x are plotted with the corresponding values of y. If the relationship between the variables is positive then a line drawn through the points will slope upward. This upward slope signifies that as the values for x increase the values corresponding values for y also increase. The opposite will be true for a negative relationship. In this case the line will slope downward and the correlation
Correlation, Regression, and T-Tests Linear regression analyses are conducted after correlation has been established (Cohen, West & Aiken, 2014). Correlation shows how two variables are related, that is how one variable behaves when the other changes. Regression analyses somehow quantify this relationship -- we use it to predict the value of the dependent variable at different values of the independent variable. Since regression analyses yield numerical values, they can only be
Quality assessments can be made, the researcher is introduced to the latest research on the subject, and it enables him or her not to waste her time on repeat searches that will bring up irrelevant results. Similar to a literature review but often more intense and broad, the meta-analysis differs from the literature review in that it highlights correlations and links between studies can critically assesses studies that it observes
Essay Topic Examples 1. The Impact of Consistent Study Routines on Academic Performance: This essay would explore how establishing regular study schedules influences students' grades by providing a framework for consistent learning and revision. Investigating whether students with structured study routines perform better academically could highlight the importance of regularity in learning. 2. Quality vs. Quantity: The
Health Education on Re-Hospitalization of Patients With Chronic Heart Failure The heart failure is one of the top health problems in the United States leading to high rate of morbidity and mortality among people aged 60 years and above. The complicated health problems of heart failure makes the readmission rates to increase within 30 days of patients' discharges. In essence, increase of readmission rate has been associated with high health
