                                  Hypothesis

 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

1.  The article, Null Hypothesis, has a definition and
example of the null hypothesis.
