so scientists can compare result
It is important to use constant in an experiments because every experiment has to have something that doesn't change while the experiment since constant means the variables that do not change in an experiment. So that's why it's important to use constant.

A constant.
A constant is something that will ALWAYS remain the same in your experiment. For instance, the materials you use and the unit of measurements you use are examples of constants. An independent variable changes with the experiments.

It's important to repeat experiments so then you know that you did the experiment right.
The constant is the value that stays the same throughout your experiment, whereas the variable value changes.

Mathematical analysis is tremendously important for understanding the result of an experiment.
so it can be a fair test
This would be 'the control group' which experiments are compared to.

Make stuff for experiments, do experiments and analyse the results of experiments.
