Best way to calculate Quartile


There are three methods for calculating Quartile as per wikipedia -->

Wanted to know which is the best method?
From my understanding, Method-3 which computes the mean of Method-1 and Method-2 seems the best method.

What are your views?

Hi @heyjag

The best method for calculating quartile is subjective, that is, it depends on individual’s requirement. You can use any of these methods to find quartile, depending on how you want to divide your data.

Of all these methods, Method 3 (using mean to define data distribution) is most widely used. I personally use this method because it gives me a clear idea of the presence of outliers in my data.
