Alternative hypothesis
The Alternative Hypothesis is a statement used in statistics that suggests there is an effect or a difference in a study or experiment. It proposes that something is happening, like a new medicine being effective or a teaching method improving student performance, as opposed to no effect at all. Researchers test the alternative hypothesis against a null hypothesis, which states there is no effect or difference. If evidence supports the alternative hypothesis, it helps to confirm the idea being tested. Essentially, it represents the idea or change that researchers aim to prove through their work.

The alternative hypothesis is a statement used in research that represents a new idea or theory that researchers want to test. It suggests that there is an effect, relationship, or difference between groups or variables, opposing the null hypothesis, which claims nothing significant is happening. For example, if a study investigates whether a new teaching method is better than the traditional one, the alternative hypothesis would state that the new method improves student performance. Researchers collect data to see if the evidence supports this alternative view.
