The relevance of the research problem is conditioned by the weak development of measurement, assessment of educational competences at an operational level, at the level of actions, by insufficient applications of psycho-pedagogical theories and methods of mathematical statistics. The aim of the work is to develop through teaching experiments the…

Recent research on curriculum-based measurement of oral reading fluency has revealed important issues in current passage development procedures, highlighting how dissimilar passages are problematic for monitoring student progress. The purpose of this paper is to describe statistical equating as an option for achieving equivalent scores across…

Linear factor analysis (FA) models can be reliably tested using test statistics based on residual covariances. We show that the same statistics can be used to reliably test the fit of item response theory (IRT) models for ordinal data (under some conditions). Hence, the fit of an FA model and of an IRT model to the same data set can now be…

Information and communications technologies today are used in virtually any university course when students prepare their papers. ICT is also needed after people are graduated from university and enter the job market. This author is an instructor in the field of informatics related to health care and social sciences at the Riga Stradins…

These proceedings contain the papers of the International Conference e-Learning 2018, which was organised by the International Association for Development of the Information Society, 17-19 July, 2018. This conference is part of the Multi Conference on Computer Science and Information Systems 2018, 17-20 July, which had a total of 617 submissions.…

The sense that replicability is an important aspect of empirical science led Killeen (2005a) to define "p[subscript rep]," the probability that a replication will result in an outcome in the same direction as that found in a current experiment. Since then, several authors have praised and criticized 'p[subscript rep]," culminating…

The technical complexities and sheer size of international large-scale assessment (LSA) databases often cause hesitation on the part of the applied researcher interested in analyzing them. Further, inappropriate choice or application of statistical methods is a common problem in applied research using these databases. This article serves as a…

Background: The imbalance between the sheer size of the developing world and what little is known about the lives and life circumstances of persons with disabilities living there should command our attention. Method: International development initiatives routinely give great priority to the collection of statistical indicators yet even the most…

The article presents numerical procedures for the validation and comparison of hierarchically organized curricula. Examples of specific hypotheses one should test, and calculations of five statistics for testing these hypotheses are given (consistency ratio, adequacy ratio, inverse consistency ratio, inverse adequacy ratio, and completeness…

The days in which the school practitioner could get by without a knowledge of statistics are over. Educators today need to be able to evaluate data, and data are statistics. It is necessary to deal with statistics when they appear and to provide them when they are needed or expected. This book attempts to provide an understanding of statistics,…

This paper argues that inferential statistical analyses as part of group research designs do not provide the kinds of data that are useful in determining the efficacy of clinical intervention with individuals having communication disorders. Replication studies are seen as providing a more fruitful approach to ascertaining the efficacy of clinical…

This paper argues that judgment-based assessment of data from multiply replicated single-subject or small-N studies should replace normative-based (p=less than 0.05) assessment of large-N research in the clinical sciences, and asserts that inferential statistics should be abandoned as a method of evaluating clinical research data.

A technique for evaluating the relationship between game statistics and outcomes of contests is proposed. The technique can be used to determine the relationship between selected game factors and winning or to determine how often various results of certain instances of play occur in a contest. (PP)

Examines historical roots of the link between statistics and psychology, exploring the way in which the conceptual framework for the application of probability in psychological research was created by experimental design. In the social sciences, statistics creates and defines objects of study more directly than in the physical sciences. (SLD)

There is a need for clarity regarding different research strategies in order to assess the relative contribution of each. Using the framework of the Facet Design Technique (FDT) for problem structuring, eight general research strategies are identified as they relate to measurement fidelity, representativeness of units, and treatment…
