Chi-square distribution

researchers determine the appropriate sample size. Now, some of you might be asking the question "what do we do once we have our hypothesis and sample population?" Well, now is a wonderful time to start experimenting with statistical methods like the chi-square test. I will explain this later on. Hypothesis A

analyze the collected data, the researchers used the statistical software - Statistical Package for the Social Services (SPSS). The collected data was analyzed using the descriptive and inferential statistics. Performed tests included the t test, the chi square (2), and the logistic regression (David, Britting, & Dalton, 2015, p. 250). The general research question was: if the addition of a cardiac acute care NP to care teams would improve utilization outcomes. To answer this question, the researchers

appropriateness of specific statistical methods in a variety of settings. Areas of emphasis include introduction to analysis of variance, regression, and graphical presentation; experimental design; descriptive statistics; sampling methods; and z, t, and chi-square. 3.0 None None Additional Material Textbook Statistics for Health Care

As a matter of fact, I decided the Goodness of Fit test for unequal expected distributions since we have four different categories of majors with different percentages expected. In addition, if I had chosen the Goodness of Fit test for equal expected results, the results would have been invalid as the model selected was not applicable

overall fitting model. What I mean by this is that in some cases, the modification indices had two suggested paths to add and regardless of which one was added the model would fit the same, or nearly the same-hundredths of a point difference in Chi-Square value. Thus, I added each path in separate models, and utilized the above fit statistics to assess which path offered the best fitting model. In most, if not all, cases these measures were near identical. Thus, the final model and path selection
