Question

Quizplus · Accepted Answer

An experiment is an activity designed to test the validity of a hypothesis. It typically involves manipulating variables and collecting data to see if the results support the hypothesis. The goal is to generate new scientific knowledge or confirm existing knowledge. A well-designed experiment may need to be repeated, but the primary purpose is to test the hypothesis. Quantitative and qualitative data can both be collected during an experiment, but the goal is not simply to collect data - it is to test the hypothesis. Manipulating as many variables as possible is not necessarily desirable, as it can make it difficult to determine which variables are responsible for any observed effects.
