Provide two different examples of how research uses hypothesis testing, and describe the criteria for rejecting the null hypothesis.
ANSWER
There are many different ways that research uses hypothesis testing. For example, a researcher may want to test whether a new medication effectively treats a specific disease. To do this, the researcher would first develop a hypothesis about how the new drug would affect the condition. They would then design a study to test this hypothesis. If the study results showed that the new medication was effective, then the null hypothesis would be rejected.
Another example of how research uses hypothesis testing is determining whether there is a relationship between two variables. For example, a researcher may want to test whether there is a relationship between smoking and lung cancer. To do this, the researcher would develop a hypothesis about how smoking affects lung cancer rates. They would then design a study to test this hypothesis. If the study results showed a relationship between smoking and lung cancer, then the null hypothesis would be rejected.
Many different criteria can be used to reject the null hypothesis. The most common standard is statistical significance. This means that the study results were so unlikely to have occurred by chance that it is statistically significant. Other criteria for rejecting the null hypothesis include practical and clinical significance. Practical relevance means that the study results are substantial enough to be relevant in the real world. Clinical significance means that the study results are significant enough to change clinical practice.
