describe three possible ways in which a hypothesis may arise.
Hypotheses may arise from prior knowledge. This prior knowledge might result from previous performed experiments, laws, theory or properties of the subjects under investigation.
Hypotheses may arise from logical inferences. A logical inference is is logical interpretation based on prior knowledge and experience.
Hypotheses may arise from imaginative guesses. It is important that this guess is NOT made to obtain results that appear to be better.
CONCLUSION: Prior knowledge, Logical Inferences, Imaginative guesses.
