Lalli geographer is interested in examining possible difference in the average moisture in four different types of soil. To explore this hypothesis, he took 10 samples for each type of soil and measured the moisture. Lalli is good in statistics and he decided to apply analysis of variance to the data. He had begun fill out the ANOVA-table but did not finish it.
