In hypothesis testing, there are two primary types of hypotheses:
Null Hypothesis (H0): This is a statement that there is no effect or no difference. It serves as the default or starting assumption that is tested against. Alternative Hypothesis (Ha): This is a statement that indicates the presence of an effect or a difference. It is what the researcher aims to support.
For example, a null hypothesis in a nursing study might state that a new wound dressing has no effect on healing time compared to the standard dressing. The alternative hypothesis would suggest that the new dressing reduces healing time.
