What does the data analysis of 7,048 environmental articles tell us about the quality of Wikipedia?

Wikipedia articles are categorized into different levels of quality, so we analyzed all 7,048 environmental articles in the Environment Assessment project on English-language Wikipedia. Based on a review of literature, we selected indicators of information quality (number of editors, number of edits, article length, number of references, and the ratio of references to words) and tested the correlation between these indicators and quality perception in the Wikipedia Assessment project. We found that articles perceived as higher quality typically have more editors and edits, are longer, and contain more references, as well as a higher ratio of references to words.
