The following table shows the grain yield of rice at six seeding
rates (Mg/ha). This was replicated 4 times. The primary objective
is to discover if there is a significant difference among the
seeding rates.

The international rice research institute in the Philippines
conducted a study of the relationship between and the yield of rice
and the amount of nitrogen fertilizer used when growing the rice. A
number of small plots of land (all the same size) were used in the
study with varying amounts of fertilizer from one plot to the
next.
When the rice is harvested, the yield (in ounces of rice) was
measured and related to the amount (in ounces) of nitrogen...
