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.
