Although both were strong advocates of statistical methods their approach was rather different. Pearson used large samples which he measured and the tried to deduce correlations in the data. Fisher, on the other hand, followed Gosset in trying to use small samples and, rather than deduce correlations, to find causes.
Kahit na parehong ay strong advocates ng statistical pamamaraan ng kanilang mga diskarte sa halip ay naiiba. Pearson ginamit malaking halimbawa na kung saan siya pantay-pantay at ang tried sa mahulo correlations sa data. Mangingisda, sa iba pang mga kamay, sinundan Gosset sa sinusubukan mong gamitin ang maliit na halimbawa at, sa halip na pagbatayan correlations, upang hanapin ang mga dahilan.
