Percentile R ank re fers to the percentage of scores that are equal to or less than a given score. Percentile ranks, like percentages, fall on a continuum from 0 to 100. For example, a percentile rank of 35 indicates that 35% of the scores in a distribution of scores fall at or below the score at the 35th percentile.
The formula for calculating percentile ranks is relatively simple and straightforward. ... The percentile rank formula is: R = P / 100 (N + 1). R represents the rank order of the score. P represents the percentile rank. N represents the number of scores in the distribution.
All the best
Hello! percentile is a little different as it is relative. Here the scores of the other students in the same exam is very important to how we calculate a person’s percentile as it gives you the idea of how good/bad you did in an exam.
If I had to summarize percentile in a formula (which will help you calculate the same for any competitive exam that you need),
Percentile = (number of people behind you/total number of people) x 100
For example, if in a class of 100 students, you topped the exam. So what this means is that your score is better than 99 people and hence your percentile is 99%ile. Again, if your rank had been 30th, that means your score is better than 70 people and hence your percentile is 70%ile.
Thus in percentile, the number of people whose score is below you or the number of people your score is better than is your percentile.
I have also covered the same (with a few more examples) in a video whose link I have shared below and while the name of the video might indicate that it could be inclined towards MBA competitive exams, the concept remains the same and is valid for any competitive exam that you appear for.Hope this helps.
