What Is A Percentile And How Can I Calculate The Percentile?

The percentile is a measure of central tendency. In statistics, the most commonly known method for calculating the percentile is with the mean. To calculate the mean we divide the number of observations that fall in our specific range by n, where n is the total number of observations.


You can also find a detailed explanation of statistics. So, we can talk about the percentile with the mean. But let’s simplify from now on, let’s just focus on some applications with the sample. And then we can take the mean and work with it in a formula.


Percentiles vs Percentile Measures


Percentiles are a special case of percents, where they are measured over a large population. If you need a quick glance about both types of measures, please check out this post to get an understanding of the different measurements.

  

What percentiles are? 


Percentiles are a way of dividing up groups of data into a set of subsets, and they determine how to treat entire populations based on their distribution. 


what is the 80th percentile


P80 = 80(n+1)/100 for ungroup data. 


P80 = L+ h/f(80n/100 - c.f_1)


80th percentile meaning


If for example, I think that the height of a group of people is to study. If a height of 1.75 m is at 80th percentile, it means that 80% of the people in the group are 1.75 or less.


The percentage symbol is denoted by '%' (example: 70%) and the percentile symbol  is denoted by 'th'(example: 25th).


So, it is easy to understand how groups should be created. But in reality, it’s tough. People can do it so much wrong. It might seems simple when applied to a limited number of variables. Yet, it takes a lot of resources to create the groups.
