Percentiles

The percentiles are finding out the certain percent of observation fall. The percentiles rank can be found out with the help of following formula.

Percentile Rank = ((B + 0.5E)/n) * 100

Where,

B = number of scores below x E = number of scores equal to x n = number of scores

• The Percentiles measure helps us to find out what percent of the total frequency was scored at or below the given measure. The percentiles rank is the percentage of scores that falls at or below a given scores.
  
• Percentiles are the easiest method to understand, when we look at the comparison of the percentage and the percentiles.
  
• When we are looking over the set of data, percentiles helps a lot in middle or median performance, or any type of the data.
  
• Percentiles are used in testing the population group when they are taken for a survey. Once again we repeating that comparison of scores are the percentiles.
