After an examination of the "macro" research approach, which deals with a population of adults, and the "micro" approach, which begins with a population of adult students, the micro approach was selected to provide reliable statistical data regarding certain characteristics of University Extension, University of California, Berkeley, students. A sample of 200 enrollees was selected to be interviewed by telephone. The survey instrument was a two-part questionnaire developed by the project and designed (1) to gather personal data about the student, and (2) to discover what the student liked or disliked about the course in which he enrolled and his relationship to, and degree of satisfaction with, University Extension. Data analyzed by the Statistical Package for the Social Sciences were also subjected to other tests: the Pearson Correlation Coefficient, crosstabulation, and factor analysis. Results were then compared with a contemporary macro study conducted in California to determine which segment of the need for postsecondary education that University Extension was successfully meeting. A secondary purpose of correlating degree of student satisfaction with service provided by Extension with demographic characteristics was frustrated by skewed results from satisfaction measures.
