Early Statistical Reasoning: An Exploratory Study of Primary School Students' Use of a Dynamic Statistics Software Package for Analyzing and Interpreting Data

Kleanthous, Irene; Meletiou-Mavrotheris, Maria - In: International Journal of Information Communication … 8 (2016) 1, pp. 26-41

This paper explores the potential of dynamic statistics software for supporting the early teaching and learning of statistical and probabilistic concepts integrated within the mathematics curriculum. It shares the experiences from a case study that implemented a data-driven approach to...

Adequate Quantification of Project Cost Risks: Introduction of Non-Linear Probabilistic (Monte Carlo) Technique

Raydugin, Yuri - In: International Journal of Risk and Contingency … 7 (2018) 4, pp. 1-20

Literature on project management contains an abundancy of references to abnormally high project cost overruns as well as bitter complaints that modern risk quantification methods could not accurately predict project cost outcomes in many cases. This article provides a) an explanation of...

Idealizations of uncertainty, and lessons from artificial intelligence

Smith, Robert Elliott - 2015

Making decisions under uncertainty is at the core of human decision-making, particularly economic decision-making. In economics, a distinction is often made between quantifiable uncertainty (risk) and un-quantifiable uncertainty (Knight, Uncertainty and Profit, 1921). However, this distinction...

Decidability in complex social choices

Amendola, Gennaro; Marengo, Luigi; Pirino, Davide; … - 2013

In this paper we develop on a geometric model of social choice among bundles of interdependent elements (objects). Social choice can be seen as a process of search for optima in a complex multi-dimensional space and objects determine a decomposition of such a space into subspaces. We present a...

Structuring Tchebycheff-Type Inequalities – A Systematical Approach / Systematisierung tschebyscheffartiger Ungleichungen – Ein Überblick

Strotmann, Harald - In: Jahrbücher für Nationalökonomie und Statistik 219 (1999) 3-4, pp. 468-493

Summary Though there is a huge variety of different Tchebycheff-type inequalities in the literature a systematised structuring is missing. The few existing surveys remain rather enumerative. Therefore in this paper a structuring of Tchebycheff-type inequalities is suggested which is based on...
