How did Mendel¿s approach to answering scientific questions differ from that of his contemporaries?

Answer 1

He kept careful records and recorded mathematical data. That was new, though we can't imagine science experiments without numbers today. In fact, the scientific society of the day didn't pay much attention to Mendel's work because he used data -- they didn't see what it had to do with science.

Answer 2

Mendel did a extensive volume of experimentation, not fairly unusual at that component. i think of the main element which stands proud as unusual is that his outcomes have been statistical, not basic definite/no questions. So he exchange into observing the proportions of diverse offspring in his pea crosses. curiously somebody calculated that the probabilities of his getting outcomes so close to actual exchange into astronomically impossible!
