octiles calculation

Octiles for grouped data Octiles are the values of arranged data which divide whole data into eight equal parts. They are 7 in numbers namely $O_1,O_2, \cdots, O_7$. Here $O_1$ is first octile, $O_2$ is second octile, $O_3$ is third octile and so on. For discrete frequency distribution, the formula for $i^{th}$ octile is $O_i …

Octiles for ungrouped data Octiles are the values of arranged data which divide whole data into eight equal parts. They are 7 in numbers namely $O_1,O_2, \cdots, O_7$. Here $O_1$ is first octile, $O_2$ is second octile, $O_3$ is third octile and so on. The formula for $i^{th}$ octile is $O_i =$ Value of $\bigg(\dfrac{i(n+1)}{8}\bigg)^{th}$ …
