Proper Writing of the Research Hypothesis
- 2. Hypothesis •A statement that defines the testable relationship you expect to see from examining the variables in your research •From this, you can make statements predicting what will happen in your research •It is employed when conducting correlational, ex post facto, quasi-experimental and experimental studies
- 4. Null hypothesis (Ho) •States that there is no relationship between variables •In correlational studies, a null hypothesis merely states that this relationship is, indeed, absent. •In experimental, quasi and pure experimental and ex post facto studies, however, a null hypothesis states that the independent variable has no effect on the dependent variable
- 5. •There is no significant relationship… •There is no significant difference…
- 6. Alternative hypothesis (Ha) •States there is a relationship between variables •Similar to Ho, Ha in correlational studies merely express existence of this relationship •This statement changes in experimental, quasi and ex post facto studies •In these studies, an Ha states that the independent variable has an effect on the dependent variable
- 7. •There is a significant relationship… •There is a significant difference…
- 8. Hypothesis can also state direction •Direction points out if the variables have a negative or positive relationship with each other •Directional hypothesis- according to specific direction (one-tailed test) •Non-directional hypothesis- does not specify a specific direction and merely states that there is a relationship between two variables (two-tailed test)
- 9. Guidelines in formulating your hypothesis •Identify the independent variable and dependent variables in your study, as they need to be stated in your hypothesis. •Your hypothesis must be falsifiable. This means that your hypothesis can be proven wrong through experiments or empirical data. •Your hypothesis must show a relationship between your variables. Will your independent variable increase, improve or decrease with the dependent variable?
