formula to find percentile?give example
Dear student,
First of all understand what is the purpose of percentile.
So, percentile tell us where a person is standing in a competition. Like how many students are there who are below him/her in the exam.
The formula for percentile is below.
Percentile = (Number of Values Below “x” / Total Number of Values) × 100
Now let us suppose, in an exam, 10 students participated and the scores of these 10 students are given below.
20, 10, 30, 50, 40, 60, 70, 80, 100, 90 respectively.
Now if the guy who scored 70 marks asked his percentile then,
First of all find 'x' which is how many students are there who scored less than him. To so this arrange the marks in ascending order.
10, 20, 30, 40, 50, 60, 70, 80, 90, 100
So from here we can say x = 6
Now Total number of values = 10
Percentile of 70 marks guy = (6/10)*100 = 60
So the guy who scored 70 marks has 60 percentile.
I hope it clarifies your doubts.
All the very best!!
