A research hypothesis is the statement created by researchers when they speculate upon the outcome of a research or experiment. Once you have identified you research question, it is time to formulate your hypothesis. While the research question is broad and includes all the variables you want your study to consider, the hypothesis is a statement that specific relationship you expect to find from your examination of these variables. When formulating the hypothesis(es) for your study, there are a few things you need to keep in mind.
Good hypotheses meet the following criteria:
- Identify the independent and dependent variables to be studied.
- Specify the nature of the relationship that exists between these variables.
- Simple (often referred to as parsimonious). It is better to be concise than to be long-winded. It is also better to have several simple hypotheses than one complicated hypothesis.
- Does not include reference to specific measures.
- Does not refer to specific statistical procedures that will be used in analysis.
- Implies the population that you are going to study.
- Is falsifiable and testable.
