Question

Based off of the tables/data below:
1) how many participants were in the sample?
2) what are the variables for the study; which are the independent variables, and which are the dependent variables?
3) what statistical analyses tests were used? (List all that were used)
4) were the findings statistically significant? (Explain which were and which were not if there were more than one hypotheses.)
5) explain the implications (what did researchers find out and can use in the applied world), from this study.

Explanation / Answer

Solution 1

The total Participants in the test can be calulated by summing over all group sizes as given in Table 1. Thus total Participants in the sample were: 56+305+45+...+569+321 = 5952

Solution 2

The study is based on a Logistic Model.

The dependent variable is: Type of Disposition, Home = 0 and Nursing Facility = 1

The Independent variable are:

Solution 3

The model developed was Logistic Regression between the dependent and the independent variables.

The test corressponding to the siginifance of the coefficient of the independent variable have been performed. The test checks if the obtained coefficient of each independent variable is significantly different from 0 or not.

Solution 4

The significance tets reluts are tabulated in Table 2.

The variable for which the coefficients were found to be significant have a p-Value (mention here as Sig) very small or less than 0.05 (for 95% confidence level).

Example Variables with significant coefficients are: Skilled Professional, Parasitic Disease, Age and others

Insignificant Varaiables are: male, Digestive Track and others (all with pValue or Sig greater than 0.05)
