Is 2 a high impact factor?

A score of 2.1 indicates that the journal is highly cited and influential within its field.

What does an impact factor of 3.5 mean?

A journal impact factor is a metric that assesses the citation rate of articles published in a particular journal over a specific time – that's usually 2 years (see below). For example, an IF of 3 means that published articles have been cited on average 3 times during the previous 2 years.

Which is better h-index or impact factor?

The journal impact factor and h index are different in their fundamental design: The former is used to measure journal prestige, while the latter is used to measure researcher impact. Therefore, the two cannot be compared.

What is a good h-index?

What is a Good H-Index? Hirsch reckons that after 20 years of research, an h-index of 20 is good, 40 is outstanding, and 60 is truly exceptional. In his paper, Hirsch shows that successful scientists do, indeed, have high h-indices: 84% of Nobel Prize winners in physics, for example, had an h-index of at least 30.

What is a good h-index after 30 years?

h index of 60 after 20 years, or 90 after 30 years, characterizes truly unique individuals.

What is the 5 year impact factor?

Does impact factor really matter?

Is The impact factor accurate?

Therefore, the IF does not accurately reflect the quality of individual articles published in a journal. Also, journals with more issues and articles can have higher Impact Factors which could be misleading as it does not really reflect the quality of articles.

What is an example of an impact factor?

For example, it only takes two extra citations to a journal with an impact factor of 0.500 which publishes 20 articles a year (and so would have an impact factor denominator of 40) to increase its score to 0.550, a 10% increase.

How good is an impact factor of 4?
