15 صفحه اولConcentration of Multivariate Statistical Tables
In this paper we lay the foundation of the concentration measurement for statistical tables with more than two columns. A concentration function and a coefficient of concentration are defined which can be used in a similar way as the Lorenz diagram and the Gini coefficient in case of tables with two columns. For computational purposes we derive an explicit formula and give an algorithm. The mat...
متن کاملFoundational Problems in Statistical Literacy: Reading Tables and Graphs of Rates, Percentages and Probabilities
College students have considerable difficulty describing and comparing the rates, percentages and probabilities found in tables and graphs. Numerous examples are presented based on actual classroom experiences. These difficulties indicate that the mastery of fractions in secondary schools is far from sufficient to master the reading and writing of sentences describing and comparing rates, perce...
متن کاملCensoring Statistical Tables to Protect Sensitive Information: Easy and Hard Problems
Protecting sensitive information in a two-dimensional table asked f o r by a statistical user of a database raises computational problems involving both the query system which should guarantee the data security, and the user who should be able to disclose a sensitive data when it is unprotected. W e provide a quadratic algorithm which allows the query system to test a censored table for securit...
