Challenge Problems
Push your limits with challenges.
Question 1
A researcher claims that the distribution of plant species in a field follows a certain pattern. After observation, they calculate a Chi-Square statistic of 15. In a table, they find the critical value at a significance level of 0.01 and degrees of freedom of 5 is 15.086. How would you interpret these results?
💡 Hint: Review how Chi-Square values compare with critical values for interpretation.
Question 2
If in a survey of household sizes, the expected family size distribution was set at 3, while the observed sizes from 100 surveyed families showed an average of 3.5 with a variance of 0.5. How would you determine the fit of your observations?
💡 Hint: Make sure to understand what variances indicate in the context of Chi-Square analysis.
