Did I answer the question correctly? Thank you for your asssitance. In a nursing home, a program is launched in 2005 to assess the extent to which its residents are affected by diabetes. Each resident has a blood test and 48 of the 625 residents have diabetes in 2005. Residents who did not already have diabetes were again tested in 2010 and 57 residents had diabetes. What is the prevalence of diabetes in 2005? Prevalence 2005= 48/625 = .0768 = 7.68% What is the cumulative incidence of diabetes over 5 years? Cumulative Incidence 5 Years= 57/625 = .0912 = 9.12% What is the prevalence of diabetes in 2010 (assume that none of the residents in 2005 have died or left the nursing home)? Prevalence 2010= 105/625 = .168 = 16.8%
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
