Are race and originating jurisdiction significantly dependent? How do you know?How many degrees of freedom are there for this chi-square table?
Step 1: Watch both of the following videos regarding chi-square analysis:
⦁ Filling Out Frequency Table for Independent Events
⦁ Contingency Table Chi-Square Test
Step 2: Calculate chi-square using the data in the table below, this Chi Square Example Handout, and the Distribution Values Chart that go with this IP.
Using the Chi-Square Example Handout and the Chi-Square Distribution Values Chart as guides to figure the calculations, calculate chi-square for the following data:
Originating Jurisdiction Caucasian African American
Denver County 16 3
El Paso County 4 6
Pueblo County 6 15
Then, answer the following questions about your results:
1. What is the column total for Caucasian?
2. What is the column total for African American?
3. What is the row total for Denver County?
4. What is the row total for El Paso County?
5. What is the row total for Pueblo County?
6. Are race and originating jurisdiction significantly dependent? How do you know?
7. What is the final chi-square value?
8. How many degrees of freedom are there for this chi-square table?
9. What is the value for the 0.05 significance level and 2 degrees of freedom on the Chi-Square Distribution Values Chart?
10. Do you reject or accept the null hypothesis that states, “Originating Jurisdiction and Race are not significantly dependent “?
