Abstract

In this research work, a statistical formula known as Kandari’s formula is devised. In comparison to traditional methods, Kandari’s formula offers a faster and easier way to determine the mean of grouped data. Traditional approaches such as the assumed mean method and step-deviation method, which claim to make difficult computations simple, have a well-known flaw: they are rather lengthy. Furthermore, these procedures are rather complex. This is when Kandari’s formula comes into play. In comparison to other techniques of finding the mean of grouped data, Kandari’s formula is simple to learn, brief, and easy to remember. In the case of large values, Kandari’s formula is also much faster and easier than the step deviation technique. Here, Kandari’s method fixes this flaw and promises to cut out hard calculations that aren’t needed and speed up the whole process.
