Here, n = Ordinal rank of the given value or value below the number. N = Number of values in the data set. P = Percentile. Rank = Percentile/100. Ordinal rank for Percentile value = Rank × Total number of values in the list.Example 1: Weather Forecasting. Statistics is used heavily in the field of weather forecasting. In particular, probability is used by weather forecasters to assess how likely it is that there will be rain, snow, clouds, etc. on a given day in a certain area. Forecasters will regularly say things like “there is a 90% chance of rain today ...The obesity rate of the United States is 10.58 percent higher than the average obesity rate. Since the standard deviation is 12.95, we see that 23.32 + 12.95 = 36.27 is the disease percentage that is one standard deviation from the mean. The U.S. disease rate is slightly less than one standard deviation from the mean. FREE SOLUTION: Q3.
