Explain the role of a hypothesis in a scientific investigation.

Short answer please quick

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.

Hope it helps!
