How to write a null hypothesis

Research yields results that can potentially change the world, depending on the type of research you're conducting of course. In order to yield credible results, however, you must know how to properly design a study. This includes properly writing a null hypothesis. A null hypothesis is defined as a statement of no change. That is, a null hypothesis describes an outcome in which there is no statistical difference between the groups you are comparing. More specifically, if a null hypothesis is fulfilled, your original hypothesis is rejected.

Instructions

  1. 1

    Write a hypothesis for the research you plan to conduct. For example, you might believe that women talk more than men do. Therefore, your hypothesis would be written like this:

    H1: Women talk more than men (note the 1 should be a subscript to H)

  2. 2

    Write "H" followed immediately by a subscript "0." This is the universal shorthand for null hypothesis. Therefore, your null hypothesis would look like this thus far:

    H0:

  3. 3

    Conceptualise a statement that indicates no difference between the experimental groups. Using the example, the statement would be:

    Women talk the same amount as men.

  4. 4

    Write your completed null hypothesis, which would look like this:

    H0: Women talk the same amount as men.
