基于正交设计的大学图书馆使用效率调查研究

A survey on the Utilization Ratio of University Library Based on Orthogonal Design

图书馆是高校的信息中心,其使用效率的高低直接反映了学员的自我学习能力。为分析图书馆的使用效率,需对图书馆设施、文献及信息检索资源现状等进行调查。论文设计了图书馆使用效率调查问卷,并基于正交设计方法进行问卷调查中样本点的选择,不仅缩减了样本空间,而且保证了样本的代表性。本文以国防科技大学三号院分馆使用效率调查研究为例,进一步阐明上述方法,并给出了效应估计与方差分析结果。参考文献12。

Library is the information center of university and its utilization ratio reflects students＇ self- learning abilities. To analyze the LUR （library utilization ratio）, we need investigate the current situations of the facility, literatures and information resources of library. This paper designs the LUR questionnaire and selects the samples based on orthogonal design which not only cuts the sample space, but also ensures the sample to be typical. Taking the LUR of our library for an example, the paper further illustrates the method above and gives the effect estimate and the result of variance analysis. 12 refs.
