Is An Activity Designed To Test The Validity Of A Hypothesis? - Fixanswer

An experiment

is designed to test the hypothesis by observing the response of one variable to changes in a limited number of other variables under controlled conditions. The data are analysed to determine whether a relationship exists which either confirms or refutes the hypothesis.
