- Complete a chi-square test of homogeneity
- Write the conclusion of a chi-square test of homogeneity in context of the problem
[latex]\chi^2[/latex], P-Value, & Conclusions
As with the chi-square goodness of fit test, we compute the value of
[latex]\dfrac{(\text{Observed}-\text{Expected})^2}{\text{Expected}}[/latex]
for each cell in the table, and then we obtain the value of the test statistic:
[latex]\chi^2=\sum\dfrac{(\text{Observed}-\text{Expected})^2}{\text{Expected}}[/latex]
Let’s use technology to compute the chi-square value and the associated P-value.
