How to fill out chi square practice problemsdate

1. To fill out chi square practice problems, follow these steps:

3. Calculate the expected frequencies for each category. This is done by assuming the null hypothesis is true and using the expected proportions for each category.
4. Compute the chi square statistic by finding the sum of [(observed frequency - expected frequency)^2 / expected frequency] for all categories.
5. Determine the degrees of freedom for the chi square distribution. This is equal to the number of categories minus 1.
6. Use a chi square table or calculator to find the critical value or p-value associated with your calculated chi square statistic and degrees of freedom.
7. Compare the calculated chi square statistic to the critical value or p-value. If the calculated statistic is greater than the critical value or p-value is less than the chosen significance level, reject the null hypothesis. Otherwise, fail to reject the null hypothesis.
8. Interpret the results by providing relevant conclusions based on the analysis.
