you experiment to test the hypothesis and see if what you predicted was true or not
When setting up an experimental procedure one prepares a control treatment as well as one or more experimental treatments. At the end of the experiment, if there is no difference between the experimental and control groups the experiment is typically said to be not conclusive. With a typical set-up, this result generally fails to lead to a rejection of the null hypothesis.
A hypothesis is what you believe will happen when you do an experiment. Scientific theory is when you use the data you have received from an experiment and create an idea that best suits your results. A theory can be related back to your original hypothesis, the experiment can prove whether your hypothesis was right.

Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
A hypothesis is a proposed explanation for a phenomenon, while experimentation involves testing this hypothesis through controlled observations or tests. Hypotheses guide experiments by providing a specific statement that can be tested and potentially supported or rejected through data collection and analysis.
Non experimental does not require hypothesis and varaiable manipulation. No cause & effect.
An experiment is the thing that you perform, and a hypothesis is the guess you make at the start (before the experiment) to determin what's going to happen.
Learn about the difference between the control group and the experimental group in a scientific experiment.
In any branch of science, "theory" and "hypothesis" are generally distinguished as post-experimental and pre-experimental. A theory is formulated after (post) experimentation and other study; it makes a claim about what is (or seems to be) actual. An "hypothesis" is formulated before (pre) experimentation and other study; it projects a claim or makes a suggestion about what might turn out to be actual.
In a controlled experiment, the control variable remains constant while the experimental variable changes with each trial of the experiment.
