I am writing an article. Is there any difference between "it is found or it was found"... or "the data are collected or were collected". As fas as I know, while writing an article it is best use present tense. Check two examples, are they same or different? : 1- It is found out that servant leadership competences and diversity management skills are at medium level 2- It was found out that servant leadership competences and diversity management skills are at medium level
