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)
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.
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
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.

example of the null hypothesis.
