Please no cursive Please and thank you

In Lesson Eleven you've seen how to use chi-square tests to answer research questions relevant to those statistical analysis procedures. Respond to the following to demonstrate your grasp of these.

  1. Describe a scenario where a researcher could use a Goodness of Fit Test to answer a research question. Fully describe the scenario and the variables involved and explain the rationale for your answer. Why is that test appropriate to use?
  2. Describe a scenario where a researcher could use a Test for Independence to answer a research question. Fully describe the scenario and the variables involved and explain the rationale for your answer. Why is that test appropriate to use?
  3. The Goodness of Fit Test and Test for Independence both use the same formula to calculate chi-square. Why? I.e., explain the logic of the test.
  4. Compare the Goodness of Fit Test and the Test for Independence in terms of the number of variables and levels of those that can be compared. In what ways are they similar or different?
  5. Describe how the Test for Independence and correlation are similar yet different.

PLEASE FILL IN BLANK WITH CORRECT ANSWERS. THANK YOU! CHAPTER 19: CHI-SQUARE TEST FOR QUALITATIVE DATA Key Terms One-way test – Evaluates whether observed frequencies for a single qualitative variable are adequately described by hypothesized or expected frequencies. Expected frequency – The hypothesized frequency for each category, given that the null hypothesis is true. Observed frequency – The obtained frequency for each category. Two-way test – Evaluates whether observed frequencies reflect the independence or two qualitative variables. Squared Cramer’s phi...

Chi Square Test We will now use Excel to run an example of a chi square test. Chi square test is checking the independence of two variables. Our example will test if taking hormonal pills and being overweight are related. We will test the independence on 200 random patients. Thus, N=200. They will be divided first into two groups, those who take hormonal pills and those who do not. Second, they will be divided into three groups based on weight,...
