M-Index Formula
MI = h/n
Variables:
- MI is the M-Index (m-quotient)
- h is the h-index
- n is the number of years since the first published paper
To calculate M-Index, divide the h-index by the number of years since the first published paper.
How to Calculate M-Index?
The following steps outline how to calculate the M-Index.
- First, determine the h-index.
- Next, determine the number of years since the first published paper.
- Next, gather the formula from above = MI = h/n.
- Finally, calculate the M-Index.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
h-index = 45
number of years since the first published paper = 30
M-Index = h/n = 45/30 = 1.5
Frequently Asked Questions
What is the h-index?
The h-index is a metric for evaluating the cumulative impact of an author’s scholarly output and performance, measuring both the productivity and citation impact of the publications.
Why is the M-Index important for researchers?
The M-Index helps in adjusting the h-index for the time factor, providing a more accurate measure of a researcher’s impact relative to their career length. It can be particularly useful for comparing the performance of researchers at different career stages.
Can the M-Index decrease over time?
Yes. The h-index generally stays the same or increases over time, but the number of years since first publication increases every year. Since MI = h / n, the M-Index can decrease if the h-index does not increase as fast as n.
How does the M-Index complement other bibliometric indicators?
The M-Index offers a time-adjusted evaluation of a researcher’s output, complementing other metrics like the h-index or the total number of citations by providing additional context regarding the researcher’s efficiency and consistency over their career.
