Welcome to our comprehensive dictionary, a resource designed to clarify and define key concepts that exist in a thesis focused on the topic: “What is the difference between hypothesis and prediction“. This book will serve as an essential guide to understanding the subtle yet crucial distinctions between these two critical elements of scientific research. The dictionary will explore the character, utility, and role of both hypothesis and prediction in scientific endeavors. The importance of this topic cannot be understated as it forms the basis for much of the scientific inquiry and research methodology. For university students writing a thesis, the ability to differentiate and apply hypothesis and prediction appropriately is central to the credibility and strength of their argument. This dictionary aims to equip you with a clear understanding of these terms, facilitating effective communication of your research and promoting robust scientific discourse.

What is the difference between hypothesis vs prediction?

The world of scientific research is filled with a myriad of terms that can sometimes be confusing. Two such terms are hypothesis and prediction. These terms, while closely related, are fundamentally distinct and are used differently in the scientific process. This article is designed to help you understand the difference between hypothesis and prediction, with practical examples to illustrate these concepts.

The Concept of a Hypothesis

A hypothesis is a tentative explanation or supposition about some phenomenon. It serves as a basis for conducting experiments and for further investigation. Hypotheses are often formulated as statements. They provide potential answers to specific research questions and are testable via observation and experimentation.

For instance, a biologist studying plant growth might propose the hypothesis: “Plants exposed to sunlight grow faster than those kept in the dark.” This statement is a hypothesis because it provides a testable explanation of a specific phenomenon.

The Concept of a Prediction

On the other hand, a prediction is a forecast of what will happen under certain conditions. It is often an outcome drawn from a hypothesis. If a hypothesis is the proposed explanation, the prediction is the expected outcome that follows from that explanation.

Using our plant growth example, a prediction might be: “If a plant is exposed to sunlight, then it will grow faster than a plant kept in the dark.” The prediction is based on the hypothesis, and it is something that can be measured and tested.


Hypothesis VS Prediction

From the above definitions, it is clear that while a hypothesis and prediction are interlinked, they serve different roles in scientific research. A hypothesis is an initial explanation that needs to be tested, while a prediction is an outcome that follows from the hypothesis.

A hypothesis is usually broad and covers a wide scope. For example, “Regular exercise improves mental health.” However, a prediction is more specific, detailing the expected results if the hypothesis holds true, like, “If an individual exercises for 30 minutes every day, their levels of stress and anxiety will decrease.”


Another distinction is that a hypothesis can generate multiple predictions. For instance, the hypothesis “A diet rich in fruits and vegetables leads to a healthier life” can lead to predictions like “People who eat five servings of fruits and vegetables a day will have lower blood pressure” or “Individuals who consume fruits and vegetables daily will have a lower risk of chronic diseases.”


Understanding the difference between hypothesis and prediction is crucial for anyone involved in scientific research, as these concepts form the backbone of the scientific method.

It is a statement about an event that will occur under specific circumstances, often formulated as an if-then statement. A prediction outlines the expected results of a study if the hypothesis is correct.

For the previously mentioned hypothesis, a corresponding prediction might be: “If a plant is exposed to sunlight, then it will grow faster than a plant in darkness”. This prediction is a specific, measurable statement that can be directly tested through an experiment.
