The author suggests several problems which can be investigated by beginning statistics students. All the problems discussed arise from the game Bingo. (SD)

Confidence intervals are an important tool to indicate uncertainty of estimates and to give an idea of probable values of an estimate if a different sample from the population was drawn or a different sample of measures was used. Standard symmetric confidence intervals for proportion estimates based on a normal approximation can yield bounds…

The purpose of this study was to develop a model for the distribution of authorships--based on the initial hypothesis that the distribution of authorships follows a shifted Waring distribution--and to test the derived model and some other discrete probability models for goodness-of-fit against empirical data. Bibliographic data from 15 abstracting…

The possibility of non-transitivity of preference choices is discussed. One example each from voting and from sports demonstrate some conditions where transitivity does not hold. Suggestions are made for using this type of problem in the classroom. (LS)

This article is the third in a series on the teaching of sets and some of the reasons for doing so. A discussion is presented of the use of set language in teaching concepts from logic, probability and algebra. (JP)

Group influence on risk taking was studied in a realistic casino setting, using blackjack as the criterion risk task and amount bet as the risk measure. (Editor)

Features of a probabilistic testing system that has been implemented on the "cerl" PLATO computer system are described. The key feature of the system is the manner in which an examinee responds to each test item; the examinee distributes probabilities among the alternatives of each item by positioning a small square on or within an…

This two-volume set is a self-help student text designed as an alternative to the standard algebra text. Each lesson is introduced by and centered around an application of the topic under discussion. For each lesson, questions are given covering the reading, testing understanding of the reading, and for discussion. Some sections contain questions…

The logical foundations of deduction and induction are outlined to form the rules for the construction of a set of tests of reasoning ability. Both deduction and induction involve the derivation of a conclusion from a set of premises. Deductive logic uses syllogisms and is abstract. Inductive logic is both empirical and abstract. Although…

This module introduces the student to a formal study of probability. The lessons progress from elementary notions of least likely to more complex considerations of the probability of occurrence of one or more possible outcomes. Probability is introduced in an empirical sense through experimentation and investigation. In the later experiments, the…

ASSOCIATIVE ADJUSTMENTS TO A DOCUMENT FILE ARE CONSIDERED AS A MEANS FOR IMPROVING RETRIEVAL. A THEORETICAL INVESTIGATION OF THE STATISTICAL PROPERTIES OF A GENERALIZED MISMATCH MEASURE WAS CARRIED OUT AND IMPROVEMENTS IN RETRIEVAL RESULTING FROM PERFORMING ASSOCIATIVE REGRESSION ADJUSTMENTS ON DATA FILE WERE EXAMINED BOTH FROM THE THEORETICAL AND…

THE PROBLEM OF THIS STUDY WAS TO FIND THE AUDIENCE OF EDUCATIONAL TELEVISION (ETV) AND TO STUDY IT IN DEPTH. THE AUDIENCES OF EIGHT ETV STATIONS - REPRESENTING THE PRINCIPAL TYPES OF OWNERSHIP, ALL SECTIONS OF THE UNITED STATES, AND BOTH VHF AND UHF CHANNELS - WERE STUDIED AND ANALYZED. IN EACH OF THE TEST COMMUNITIES, SAMPLES WERE DRAWN FROM THE…

This is part two of a two-part SMSG mathematics text for junior high school students. Key ideas emphasized are structure of arithmetic from an algebraic viewpoint, the real number system as a progressing development, and metric and non-metric relations in geometry. Chapter topics include real numbers, similar triangles, variation, non-metric…
