What is decile and its formula?
Decile Formula There are several formulae in vogue to calculate decile, and this method is one of the simplest one where each decile is calculated by adding one to the number of data in the population, then divide the sum by ten and then finally multiply the result by the rank of the decile, i.e., 1 for D1, 2 for D2…
How do you calculate decile?
To find the decile, first order the data from least to greatest. Then, divide the data by 10. This indicates the number of observed values within each decile. Using our previous example, we divide our data into 10 groups, each containing 10% of the data.
What is the 1st decile?
Deciles are the percentiles that are multiples of 10. For example, the first decile is the point with 10% of the data below it and 90% above it while the ninth decile is the point with 90% of the data below it and 10% above it. This index identifies the element in the sorted data set that is the decile value.
What is percentile and decile?

Percentiles are frequently used to understand test scores and biometric measurements.
