a hypothesis
If you do not know the answer to something, you can start by making a hypothesis.
...perform a scientific experiment designed to shed light on the hypothesis.
After making a hypothesis, the next step in the scientific method is to conduct an experiment to test the hypothesis. This involves collecting data and analyzing results to determine if the hypothesis is supported or refuted.

The term hypothesis is used in science and statistics. I have included two links related to the these terms.In statistics, the null and alternative hypothesis are mathematical statements used in statistical decision making. An example of a null hypothesis is the mean of the population from which a sample was obtained is equal to 10. The mean of the data is sufficiently different from 10 can be used to reject the null hypothesis.As used in science, hypothesis is the initial idea suggested by observation or preliminary experimentation. See related links.
The null hypothesis is that there is no change in the population mean while the alternative hypothesis is that there is a change in the mean. The null hypothesis is stated as Ho:Mu=? in statistics while the alternative hypothesis is stated as Ho:Mu(<,>,≠)? depending on whether you are looking for mu to be greater, less than, or not equal to population mean.
