Use the data in Table 315 to calculate the risk and odds ratios Risk ratio 50 ⁄ 10 = 50 Odds ratio Notice that the odds ratio of 52 is close to the risk ratio of 50 That is one of the attractive features of the odds ratio — when the health outcome is uncommon, the odds ratio provides a reasonable approximation of the risk ratioRelative Risk and Odds Ratio Calculator This Relative Risk and Odds Ratio calculator allows you to determine the comparative risk of the occurrence of a significant event (or outcome) for two groups For example, suppose the members of one group each eat a kilo of cheese every day, and the members of another group eat no cheese, and you have An odds ratio is a ratio of two odds Relative risk is a ratio of two probabilities The following example shows how to calculate and interpret an odds ratio and relative risk in a reallife situation Example Calculating Odds Ratio an d Relative Risk Suppose 100 basketball players use a new training program and 100 players use an old
