Charles Darwin conducted an experiment to examine the superiority of
cross-fertilized plants over self-fertilized plants. 15 pairs of
plants were used. Each pair consisted of one cross-fertilized plant
and one self-fertilized plant which germinated at the same time and
grew in the same pot. The heights of the plants were measured at a
fixed time after planting. Four different pots were used.
