Three Ways of Stating Hypotheses
2. Alternate Form
The alternate form states that there is a significant difference between the results of two conditions or situations being tested.
- Example:
- Varying salt concentrations will affect rice seeds germination.
This means that there is a significant difference in the average number of germinated seeds under varying salt concentrations.
Note that the null form of the hypothesis takes on a negative statement, while the alternate form takes on a positive statement. Both null and alternate forms indicate that the numerical data of an experiment may be analyzed statistically so most of the time, these two forms are used in research problems that require statistical analysis.
3. If-Then Statement
The if-then statement states that if a certain condition (cause) is applied, then a corresponding observation (effect) occurs. It is the form that is suggested for neophyte experimenters.
- Example:
- If rice seeds are soaked in varying salt concentrations, then the germination of the seeds will be inhibited.
