"98%" typically refers to a percentage that indicates a high level of completion, accuracy, or agreement. In various contexts, it can signify that something is almost fully achieved or that a particular measurement is very close to a whole. For example, if a project is 98% complete, it means only a small portion remains to be finished. In statistics, a 98% confidence interval suggests that there is a 98% probability that a parameter lies within a specified range. This concept is often used in fields like science, economics, and social research to convey the reliability of data and findings.
