What are the common significance level percentages used in chi squared tests?

• A. 1, 2, and 5 percent
• B. 1, 3, and 10 percent
• C. 1, 5, and 10 percent
• D. 1, 5, and 15 percent

Answer: (C)

The significance levels commonly used in chi-squared tests are typically 1%, 5%, and 10%. These levels indicate the probability of rejecting the null hypothesis when it is, in fact, true (Type I error). The 1% level is often used when researchers want a very stringent criterion for significance, minimizing the chances of falsely concluding that there is an effect or relationship. The 5% level is the most widely used threshold in social sciences, balancing sensitivity to detect an effect while still being reasonably conservative. The 10% level is sometimes chosen in exploratory research where researchers are willing to accept a higher risk for potential findings that warrant further investigation. Each of these percentages reflects the degree of confidence a researcher aims to have when drawing conclusions from their data. While other significance levels may exist, these three are considered standard in most statistical analyses utilizing chi-squared tests.
