The Alternative Hypothesis is the statement that you want to prove or support. It’s the opposite of the null hypothesis – it claims that there is a significant difference or relationship between variables.
- Contradicts the null hypothesis: It’s the opposite of the null hypothesis.
- Research question: Often reflects the researcher’s belief or expectation.
- Types: Can be one-tailed (directional) or two-tailed (non-directional).
Example:
In a drug testing example, the alternative hypothesis would be: “There is a difference in blood pressure between people who take the new drug and those who take a placebo.”
The Alternative Hypothesis is the claim you’re trying to establish through your research. If the data provides sufficient evidence to reject the null hypothesis, you can support the alternative hypothesis.
