Answer:
A hypothesis is a testable proposition
used to explain scientific phenomena. It
may be based on previous observations
(a sort of educated guess) or it may
simply be a hunch. Most scientific
hypotheses are combinations of
observation and intuition. The important
thing is that the hypothesis be testable.
If the hypothesis is disproved through
testing, then it is discarded and a new
hypothesis is proposed. If the hypothesis
stands up to rigorous testing, then our
faith in the hypothesis is increased.
This system of careful, rigorous, and
unbiased testing of a hypothesis is what
characterizes the scientific method.
