List of top Mathematics and Quantitative Ecology Questions on Analysis of variance (ANOVA)

A researcher measures the abundance of a tree species in 10 plots in each of two habitats. She tests for differences in abundance between the two habitats using an ANOVA. The results from the ANOVA are as follows: \[\begin{array}{rl} \bullet & \text{Mean abundance in habitat A = 30 trees} \\ \bullet & \text{Mean abundance in habitat B = 50 trees} \\ \bullet & \text{F-statistic (on 1 and 18 degrees of freedom) = 6.04} \\ \bullet & \text{P-value = 0.02} \\ \end{array}\] Here, a P-value of 0.02 means that:
