Graphic statistics as developed by John Tukey have some practical benefits for precision journalists as they assist in spotting trends not as easily noted without the use of nonparametric statistics. Some especially helpful graphic statistics are: "stem-and-leaf display,""box plots,""froots," and "flogs."…

This study analyzes statistics of 17 public services units of the University of Colorado at Boulder libraries, measuring frequency of question-asking, types of questions and staff responsibility. The study seeks to determine fluctuations of reference service workloads over time, department staffing and training needs, and to provide supervisors…

The feasibility of generalized approaches to training military personnel in the use of different types of sonar/acoustic warfare systems was explored. The initial phase of the project consisted of the analysis of representative sonar and acoustic equipment to identify training areas and operator performance requirements that could be subjected to…

The process of revising the National Center for Higher Education Management Systems (NCHEMS) Program Classification Structure (PCS) is now completed. This document is being distributed to inform NCHEMS constituents about the final revisions to the PCS and to describe the reasons why each revision was made. The revision process began in early 1974…

Several statistical techniques that can be used to ameliorate the difficulties inherent in the data analysis of longitudinal studies are presented. The first step in longitudinal data analysis is graphing. This permits visual inspection of the data, and with educated viewing can yield insights into the nature of the underlying mechanisms. The next…

Questionnaires are important research tools despite their unpopularity. They are generally less costly per response than other techniques, may elicit more candid answers, provide more time for respondents to consider their replies, and do not introduce interviewer or observer bias. The rate of return is an indication of the usefulness of a…

The objective of this research is to provide an outline of evaluation by objectives for a conference entitled Project Evaluation. As far as processes are concerned, this evaluation will result in a session-by-session evaluation form and transparencies to accompany the session-by-session evaluation form and to reinforce the main points under…

The NCHEMS Costing and Data Management System is designed to assist institutions in the implementation of cost studies. There are at least two kinds of cost studies: historical cost studies which display cost-related data that reflect actual events over a specific prior time period, and predictive cost studies which forecast costs that will be…

The statistical technique of analyzing data collected at regular intervals to reveal periodic components of the data is described by reference to actual records. The data chosen for illustration include tide height in a river; biochemical oxygen demand and dissolved oxygen in the same river; discharged salt into a river system and its relation to…

The general purpose of this project was to initiate, implement and evaluate a program concerned with developing improved and more effective techniques for the reduction or prevention of learning and behavior problems in children. The children included in the PACE I.D. Center Study were an extreme group as far as behavior and learning problems were…

A study was conducted to observe the varying degree of consistency between three sources of data with respect to the same classroom phenomenon. Data was gathered in a public high school near Detroit in 1969. Using the basic 10-category Flanders interaction analysis system, systematic observations of controversial issues discussions were made in…

PAVLOV (Paired Associate Verbal Learning Organizational Vehicle) is a Fortran coded program designed to facilitate the analysis of learning data. The program analyzes four classes of information parameters, list order, data format, and data. Utilizing this input, the program performs an in-depth measurement of several dependent variables for each…

This report, divided into six sections, is a summary of a study to research the costs of implementing Individually Guided Instruction (IGE). Section 1 introduces IGE and gives a brief overview of all studies conducted as part of the Institute for Development of Educational Activities grant to Teachers College, University of Nebraska. Section 2,…

This report is a companion analysis to the Statewide educational needs assessment (EA 005 415). The companion analysis is not a completed study, but rather a feasibility study that asks some questions of some data as a heuristic device delimiting some parameters for further efforts within the Wisconsin State Department of Education. The data…

The use of Kruskal's nonmetric multidimensional scaling model for analysis of classroom interaction data is discussed. Four distance models are proposed which lead to multidimensional representation of single sequences, sets of sequences, and behavior categories using symmetric and conditional proximity options of the model. Results of application…
