WebPercentiles are calculated by ordering the values of a variable from lowest to highest, and then finding the value that corresponds to whatever percent you are interested in, in this case, 1%. Hence, 1% of the values of the variable write are equal to or less than 31. f. 25% – This is the 25th percentile, also known as the first quartile. g.

WebThere is an easier way to recode mpg to three categories using generate and recode. First, we make a copy of mpg, calling it mpg3a. Then, we use recode to convert mpg3a into three categories: min-18 into 1, 19-23 into 2, and 24-max into 3. generate mpg3a = mpg recode mpg3a (min/18=1) (19/23=2) (24/max=3) (74 changes made) WebThe point is that pctile gives the inverse of what the OP wants. Given say 1 3 7 13 21 in a variable, pctile tells you say that the median is 7, but any resulting variable is not aligned with the original data. What the OP wants is that the observation containing 7, which is the median, has a percentile rank of 0.5 as a fraction or 50 as a percent.
