Example: A relative risk of 4 might have a confidence interval of 1.05 to 9, suggesting that although the estimate is for a 400% increased risk, an increased risk of 5% to 900% is plausible.

For example, tables or graphs are used to organize data, and descriptive values such as the average score are used to summarize data.
