In this paper, the relationship between personality traits and the parameters of certain social networks is investigated directly through data collection by precise questionnaire surveys. First, social network analysis is employed to calculate multiple parameters of the networks. Then, a correlation analysis is conducted on the relationship between the personality traits and the parameters. The results show that some network parameters are in consistent with the students’ personality traits. Results also reveal that the parameters of the respondents who mark themselves as “extroverted” are much closer to those of respondents who mark themselves as “neutral” than “introverted”.
