For this discussion, you will create an example to which the chi-square test of independence could be applied. Develop a main response in which you address the following:

  • Identify two categorical variables for which a chi-square test of independence could be conducted.
  • Describe the categories of each.
  • Explain why these would be appropriate for this test.
  • Predict whether or not the chi-square test result would be significant, and what this would imply about the variables.

Solutions

Expert Solution

Two categorical variable and description for categories is given under the problem heading.

These would be appropriate for the test because a key assumption of the chi square test of independence is that each subject contributes data to only one cell. Therefore the sum of all cell frequencies in the table must be the same as the number of subjects in the experiment.

x-square = 26.2596

p-value =0.00002805

Since p-value is less than 0.05. we concluded that the tenure status of the farms are independent of a levels of soil fertility. And chi-square would be significant.

Lets apply the Chi-square Test of Independence to our example where we have as random sample of 500 U.S. adults who are questioned regarding their political affiliation and opinion on a tax reform bill. We will test if the political affiliation and the opinion on a tax reform bill are dependent at a 5% level of significance. The observer contingency table is given below. Also we often want to include each cell's expected count and contribution to the Chi-square test...

In a research article, the authors said that they used a chi-square test for independence for testing whether there is statistically significant correlation between two categorical variables. Each of categorical variables has two categories of outcomes. So, the contingency table for crossclassifying these two variables is a 2x2 table. They reported the chi-square statstic value for this test of independence and it is 5.21. Please mark all statements that are correct. A The correlation between the two categorical variables is...

The Chi-Square test of independence is used to determine if there is a significant relationship between two nominal categorical variables. The frequency of one nominal variable is compared with different values of the second nominal variable. The chi-squared goodness of fit test is appropriate when the following conditions are met: The sampling method is simple random sampling The variable under study is categorical The expected value of the number of sample observations in each level of the variable is at...
