How to Calculate Decile?
Calculate the decile of any given set of data following the steps given below:
Sort the Data: Arrange the data points in ascending order from smallest to largest.
Identify Decile Number: Decide which decile you want to find (e.g., 1st decile, 2nd decile, etc.).
Calculate Position: For ungrouped data, use the formula:
Decilen = ( n/10 )×(N+1)
Where:
- Decilen is the nth decile.
- n is the decile number.
- N is the total number of data points.
NOTE: For grouped data, use cumulative frequency to find the position of the decile.
Find the Value: Once you have the position, locate the corresponding value in the sorted data set. This value represents the decile.
Decile – Definition, Formula, Rank, Examples
Decile is a statistical measure that divides a dataset into ten equal parts, and each part contains 10% of the data. It is different from percentage as in percentage there are 100 parts. In this article, we will learn in detail about what is decile, the formulas of decile (grouped data and ungrouped data)
