      the absolute risks of sexual dysfunction with venlafaxine and placebo are 20.00% and 8.33%, respectively. The RR is therefore 20.00/8.33, or 2.40. Clinical Points The absolute risk is the probability of an event in a sample or population of interest. The relative risk (RR) is the risk of the event in an experimental group relative to that

      The absolute difference is 215 – 75 = 140. From this, we could say “Albertsons has 140 more stores than QFC.” However, if you wrote this in an article or paper, that number does not mean much. The relative difference may be more meaningful. There are two different relative changes we could calculate, depending on which store we use as the ...

      2 The above calculations are the absolute uncertainty of a measurement. The relative uncertainty of a measured value can be determined by dividing the standard deviation by the average value. If you multiply the relative uncertainty by 100, then you obtain the percent standard deviation.
