Provides an introduction to sampling, determination of sample size, and selection of the actual sample that would be useful for librarians conducting research and evaluation studies. Highlights include sampling method, sampling error, confidence level, and microcomputer software packages that help determine sample size. (Contains 26 references.)…

Notes that the availability of statistical software packages has led to a sharp increase in use of complex research designs and complex statistical analyses in communication research. Reports a series of Monte Carlo simulations which demonstrate that this complexity may come at a heavier cost than many communication researchers realize. Warns…

Reports the design, methodology, and results of a research project which examined the effectiveness of bibliographic displays produced by online catalogs. A means of testing displays against several hundred thousand records at a reasonable cost and using that to test several display possibilities is described. (CLB)

Presents an overview of computer assisted instruction (CAI) as an instructional technique; describes studies on CAI effectiveness in compensatory education; discusses elements that need to be addressed to create a positive relationship between CAI, compensatory education, and achievement gains; and reviews evaluation designs appropriate in…

The process of focus-finding in qualitative research is ongoing and dynamic, involves researcher choices and decisions (rather than pure discovery), and is a process of social construction in which the researcher interacts with the research setting. Focus-finding is discussed in the context of a qualitative research study of the integration of…

Researchers of gender differences in computer-related behaviors have reported a confusing picture. When asked which sex is more positive toward computers, more apt at using computers, and more likely to use a computer, one would be best advised to answer "it depends." It depends on what attitudes you are measuring, what skills you are…
