... RR: Relative Risk or Risk Ratio HR: Hazard Ratio All three are ratios of risk- one test group is reflected in the numerator, the other in the denominator- therefore, if you get a ratio = “1” that means there’s NO DIFFERENCE between groups. Keep this in mind while we look at them individually. ...

(b) Katie’s 93 puts her at the 96th percentile, because 24 out of 25 test scores fall below her result. (c) Two students scor ...
