A [[prediction]] is when a scientist uses a [[hypothesis]] to suggest what the [[results]] of an [[experiment]] might be before performing it.
===About Predictions===
: A [[prediction]] may be based on a previous [[observation]] or on the [[results]] of other [[experiment]]s or [[investigation]]s.
: A [[prediction]] should be based on scientific ideas and not just a guess.
: The [[results]] of one [[experiment]] can be used to '''predict''' the [[results]] of another [[experiment]].
: A [[hypothesis]] often provides a [[prediction]] for an [[experiment]] as [[experiment]]s are usually designed to prove a [[hypothesis]] to be incorrect if possible.
