The large sample size allowed Gregor Mendel to make comparisons quantitatively. The <em>"margin of error"</em> is narrower and it allowed him to<em><u> detect statistically significant results</u></em> through its statistical power.<em> Large sample sizes have a greater statistical power.</em> However, it takes a lot of t<em>ime, effort and money.</em> Mendel was very persistent and had the driving force.
