Title

Reference service evaluation and meta analysis : findings and methodological issues

Library quarterly. 67(1997) no.3, S.267-289

Abstract

Meta analysis can be used to synthesize the large volume of data describing numerous independent variables and their correlations with reference accuracy. Presents a study which addresses the following questions: How often have the same variables been examined across different studies? To what extent do the observed correlations agree or differ? and Can the results of multiple studies be combined to obtain a more accurate estimate of the strength of association for a given variable with reference accurary? Consistent findings across studies would suggest that reference accuracy has some relationship with the independent variable in question
