Financial analysts generally create static formulas for the computation of NPV. When they do so, however, it is not readily apparent how sensitive the value of NPV is to changes in multiple interdependent and interrelated variables. It is the aim of this paper to analyze this variability by employing a dynamic, visually graphic presentation using…

This paper presents a set of guidelines for reporting on five types of quantitative data issues: (1) Descriptive statistics, (2) Effect sizes and confidence intervals, (3) Instrument reliability, (4) Visual displays of data, and (5) Raw data. Our recommendations are derived mainly from various professional sources related to L2 research but…

One option for Extension professionals wishing to use free statistical software is to use online calculators, which are useful for common, simple analyses. A second option is to use a free computing environment capable of performing statistical analyses, like R-project. R-project is free, cross-platform, powerful, and respected, but may be…

Presents a histogram drawing program which sorts real numbers in up to 30 categories. Entered data are sorted and saved in a text file which is then used to generate the histogram. Complete Applesoft program listings are included. (JN)

Students in higher education today are technologically savvy and expect faculty to use myriad web technologies for course delivery. This includes taking advantage of email, course web sites, and online learning communities. However, expectations now also include RSS, blogs, web-, pod-, and vod-casting, extending the classroom experience to provide…

Proposes that a semiotic approach can be used as a supplementary method in assessing the denotations and connotations of the signs and their relationships in computer learning environments. Utilizes the semiotic framework to study visual images, especially how multiple, interactive, and manipulative statistical representations affect the…

Describes a computer application that uses graphics, color, and animation to make the learning of statistical reasoning with uncertainty easier and more fun. Notes that the initial implementation focuses on the Dempster-Shafer model, although the design is a framework that can incorporate other models. Also discusses how the tool may be used to…

Describes VisiCalc, a programmed package for use with the Apple II microcomputer and discusses the use of this program for two library tasks--statistical analysis and budgeting. System features are described in the context of these applications and six tables illustrating system output are appended. Additional resources are listed. (RAA)

The use of computer graphics techniques in a study of attrition at the University of Akron is outlined to illustrate potential applications. The techniques produce information that is more readily interpreted than the usual data tables. Specific software information and illustrations are included. (MSE)

Describes computerized differential classifications of a variety of subtle brain dysfunctions. Provides objective corroboration that may be a useful adjunct to psychiatric diagnoses. Discusses independent criteria for diagnostic validity, evaluation of treatment efficacy and more individualized treatment. Outlines the implications of this…
