An hypothesis is an important scientific concept.   Thus, it is important to define hypothesis.  What is an hypothesis?  Below is a definition of an hypothesis with respect to scientific research. (1)

Hypothesis Definition:

A hypothesis (which may be based on theory or prior findings) is a prediction concerning the relationship between variables or the outcome of a scientific study. 

Hypothesis Examples:

      Providing examples of hypotheses may help to clarify the meaning of an hypothesis, and also help in learning how to write an hypothesis. 


      Below are two examples:

1.   Imagine you were interested in investigating the influence of humor in ads on sales.  Your hypothesis could be the following:

A funny ad will result in more sales than an ad that is not funny.

2.  Now imagine that you were interested in investigating whether the number of pages in a book influences book sales.  Your hypothesis could be the following:

Books with more pages will sell more copies.

Notes
