Provides a brief overview of single-subject research designs. This method exercises its power by examining changes in single subjects' responses over time across experimental conditions. Describes a classroom project in which students collect repeated measures of their own behavior and graph the data. (MJP)

Details theoretical and practical uses for Statistics Canada's E-STAT CD-ROM in helping preservice teachers explore the local communities in which they are to teach. Claims that E-STAT allows users to learn mapping and graphing skills and to confront their preconceptions about particular locales. Notes possible uses in social studies instruction.…

Coordinate graphs of time-series data have been significant in the history of statistical graphing and in recent school mathematics curricula. A survey task to construct a graph to represent data about temperature change over time was administered to 133 students in Grades 3, 5, 7, and 9. Four response levels described the degree to which students…

In statistical terms, transfer rates require two components: a numerator that represents community college students who transfer and a denominator that approximates the pool of potential transfer students. The California Task Force adopted a set of criteria to judge the appropriateness of prospective pairs of numerators and denominators. Its form…

Interest in Total Quality Management (TQM) at institutions of higher education has been stressed in recent years as an important area of activity for institutional researchers. Two previous AIR Forum papers have presented some of the statistical and graphical methods used for TQM. This paper, the third in the series, first discusses some of the…

A reporting and study format for the investigation of university student retention is presented. Student progression and loss is shown graphically and in tabular form to enable ready comprehension and encourage data exploration. Data obtained at Virginia Commonwealth University for 1977-80 are used as illustration. Two ways of viewing student…

The focus of this study was on the relationship between visual and statistical analyses of time series data and the degree to which characteristics of the data influenced this relationship. A total of 52 teachers took part in evaluating a series of graphs having prespecified characteristics. The independent variables manipulated included: slope,…

A modified form of vector analysis is examined that was applied to graphs depicting the number of undergraduate student credit hours taken by majors and nonmajors in each of 18 arts and sciences departments. The analysis permitted the identification of instructional service strategies adopted by various academic units and the evaluation of the…

This learning unit on looking at figures is one in the Choice Series, a self-learning development program for supervisors. Purpose stated for the approximately eight-hour-long unit is to enable the supervisor to understand information displayed in charts, tables, and graphs; produce charts, tables, and graphs from figures; compare different sets…

The dominant driving force of past movements in West German output and prices is investigated and a review of government policy undertaken to stabilize these movements is presented. Three alternative impulse hypotheses are tested: the monetary, the fiscal, and the foreign impulse hypothesis. The major results of the tests are that: (1) monetary…

This study explored some practical issues for single-case researchers who rely on visual analysis of graphed data, but who also may consider supplemental use of promising statistical analysis techniques. The study sought to answer three major questions: (a) What is a typical range of effect sizes from these analytic techniques for data from…

The first in a series of 53 publications designed to provide information relative to human service decision makers, this datebook constitutes a statistical summary of the socioeconomic problems of children and families with children in Pennsylvania's 67 counties. Data taken from the 1970 U.S. Census Report are presented via 24 tables, 15 figures,…

This paper examines ways in which coherent reasoning about key concepts such as variability, sampling, data, and distribution can be developed as part of statistics education. Instructional activities that could support such reasoning were developed through design research conducted with students in grades 7 and 8. Results are reported from a…

A new statistical measure termed the Composite Indicator of Changes (CIC) reflects overall changes in average salaries and wages paid by public school systems in much the same way that the Dow-Jones averages reflect price changes in the stock market. The CIC is useful for comparing salary trends among various categories of personnel, among…
