摘要
本文通过一个模糊统计试验,对宁波大学各年级男女学生就"中年人"年龄隶属问题进行抽样调查,分析统计数据,计算出各个年龄对于"中年"的相对隶属频率及其频率稳定性,描绘出"中年人"隶属函数曲线,推得一个"中年人"隶属函数公式,并就此项研究工作的意义,对社会学和心理学方面的实用价值进行了阐述和剖析。
A sample survey on the conception of the middle-aged is carried out among the students of Ningbo University. Based on the survey, a membership function of the middle-aged is established by fuzzy statistics. The result in the paper may be useful for psychological and sociological analysis of population.
