How to calculate percentile score in aiims?
Answers
A percentile (or centile) is the value of a variable below which a certain percent of observations fall. So the 20th percentile is the value (or score) below which 20 percent of the observations may be found. The term percentile and the related term percentile rank are often used in descriptive statistics as well as in the reporting of scores from norm-referenced tests.
Your percentile score = { (No, of people who got less than you/ equal to you) / (no. of people appearing in the exam) } x 100
Thus, if in an exam, 10 people give the test and 9 people get either less than what you got or equal to what you got, your percentile score is:
{9/10} x 100 = 90 percentile.
It is used in CAT and many other such entrance exams. Thus, the higher percenilte, the better marks but, it is different from percentage and sop, percentile gives an idea of relative performance with others and not how high you scored out of the total marks.
