Q. What is conclusion in the experiment?
A conclusion is a judgment based on the data acquired in the experiment. If data support a hypothesis then the hypothesis is tentatively affirmed. Hypotheses are never proven that they are always subject to additional research. If additional data don't support a hypothesis the hypothesis is discarded or modified. Most hypotheses aren't supported by data. Whether the hypothesis is sustain or not the data collected may still be useful. Over time data from several experiments can be used to form a verbal, visual and/or mathematical explanation- called a model-of the phenomenon being studied.
