Question

Write short note on deciles.

Answer 1

In a similar way, thedeciles of a distribution are the nine values that split the data set into ten equal parts. You should not try to calculatedeciles from small data sets -- a single class of marks is too small to get useful values since the extreme deciles are very variable.

Answer 2

Explanation:

A decile is a statistical method of dividing a collection of graded data into 10 parts of equal size. Such form of data ranking is carried out in the fields of finance and economics as part of many academic and quantitative studies. The data may rank from the highest to the lowest value, or vice versa.

A decile is used to assign decile ranks to a set of data. A decile rank arranges the information from the lowest to the highest and takes place on a scale of one to ten where each successive number corresponds to a 10 percentage point rise as there are nine decile marks. The 1st decile, or D1, is the point below 10% of the observations, D2 has 20% of the observations below it, D3 has 30% of the observations below it, and so on.
