18. What Is Our Hypothesis?
Falsifiable
“A hypothesis must also be falsifiable. That is, there must be a possible negative answer.
For example, if I hypothesize that all green apples are sour, tasting one that is sweet will
falsify the hypothesis.”
* Source: The Process of Science - NCSU
Verifiable
“To meet the standards of science, a hypothesis must be verifiable Some potential
hypotheses clearly cannot be tested. For example, I might propose that my colds are the
result of someone practicing voodoo on me. Science can only measure that which is part of
nature, so supernatural phenomena could never be studied or predicted by scientific
methodology.
21. "If you can not measure it, you can
not improve it.“
– Lord Kelvin
“Statistics are like a bikini. What
they reveal is interesting. But what
they hide is vital.”
– Aaron Levenstein
