How do you begin a hypothesis?

  1. Variables in hypotheses. Hypotheses propose a relationship between two or more variables.
  2. Ask a question. Writing a hypothesis begins with a research question that you want to answer.

  4. Formulate your hypothesis.
  5. Refine your hypothesis.
  6. Phrase your hypothesis in three ways.
  7. Write a null hypothesis.

Can a hypothesis be a question?

Before you make a hypothesis, you have to clearly identify the question you are interested in studying. A hypothesis is a statement, not a question. Your hypothesis is not the scientific question in your project. The hypothesis is an educated, testable prediction about what will happen.

A hypothesis is a prediction you create prior to running an experiment. The common format is: If [cause], then [effect], because [rationale]. In the world of experience optimization, strong hypotheses consist of three distinct parts: a definition of the problem, a proposed solution, and a result.
