The impact factor;-
The impact factor is a measure of the frequency with which the "average article" in a journal has been cited in a particular year. The annual impact factor is a ratio between citations and recent citable journals published. Thus, the impact factor of a journal is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years.
The 2018 impact factor of a journal would be calculated as follows:
2018 impact factor = A/B
where:
A = the number of times that all items published in that journal in 2016 and 2017 were cited by indexed publications during 2018.
B = the total number of "citable items" published by that journal in 2016 and 2017.
