Important announcement

Dear visitor,

Please note that this OpenCourseWare platform will be replaced at the end of 2026 by a new platform (under the same url ocw.tudelft.nl).

Courses and their contents that are currently available the platform will partly be migrated. URL’s for this content will change and content might be unavailable for some time. In addition, some courses will not be available anymore.

If you are linking to specific courses on this platform (for instance for your students), please take timely measures to avoid problems with access. Possible actions are:

  • Download the materials to your local platform (laptop, server)
  • For educators only (including TU Delft lecturers): Contact us at ocw@tudelft.nl and inform us what course you are using in what context (institute, program, period of use, number of students). We will research (in collaboration with the authors of the course) and decide if we will migrate the course, and if yes, can supply you with a new url.

Thank you.

2.1.4 Main Takeaways on Research Questions and Hypothesis

Course subject(s) Module 2. Phases & Methods of Scientific Research

Main Takeaways on Hypotheses

Hypothesis: a proposed explanation for a phenomenon that can be tested by scientific research and experimentation.

A hypothesis must meet two requirements:

  1. It must contain an educated prediction of the answer to the research question
  2. It must be testable

A well-formulated hypothesis contains at least one dependent and at least one independent variable, in which the independent variable is the assumed cause or predictor, and the dependent variable the assumed effect or outcome.

The typical format of a hypothesis is:

“Varying independent variable x for a certain population,

leads to a described effect

on dependent variable y for that population”

In qualitative research, when carrying out statistical analyses, you will often need to formulate a null Hypotheses H₀ and an Alternative Hypothesis H₁.

Null hypothesis H₀: the default prediction that there is no association between the dependent and the independent variables

Alternative Hypothesis H₁: the prediction that there is an association of some sort between the dependent and the independent variables
