The next concept that we are going to see is person percentiles, if you see is actually a measure of
dispersion.
Let me explain this using an example, percentile is a way to rank the data.
Here you see the height of different people are being analyzed and there are 20 people in this group.
Suppose if someone sees the 80th percentile is five feet, 11 inches, it means.
Eighty percent of the people are below five feet and 11 inches, this person, this person side is five
feet, 11 inches.
If this person corresponds to the 80th percentile, 80 percent of the people are below this person.
Right, in terms of height.
Right.
So, you see, percentile is the ranking mechanism.
This concept is used in competitive exams like it said Gary Gmod cat, you know, to rank these students
performance.
We going to use the concept of percentile to understand dispersion and also to identify outliers, outliers
will be covered in other.
