    Abstract:
    Research has shown that adults have intuitions about probability and statistics that, in many cases, are at odds with accepted theory. The existence of these strongly-held ideas may explain, in part, why learning probability and statistics is especially problematic. One objective of introductory instruction ought to be to help students replace these informal conceptions with more normative ones. Based on this research, items are currently being developed to assess conceptual understanding before and after instruction.

    Abstract:
    When constructing assessment instruments both the purpose of the assessment (feedback, grading) and the skills which are being assessed need to be considered. The main purpose of this chapter is to help teachers develop their own assessment instruments by giving specific examples of tasks. Unsatisfactory tasks are used to illustrate the pitfalls, and alternative versions are given as examples of good practice. Some comments on grading are included. The emphasis is on written assessment in the classroom, mainly of pupils aged about 14-19, but much is relevant also to introductory statistics courses at college and university level. Consideration is given to ways of assessing factual knowledge, the ability to use computers, understanding of concepts and application of techniques, and communication skills. The pros and cons of multiple choice and open-ended questions are discussed as are the challenges of oral assessment and assessment of group work.

    Abstract:
    Spreadsheet software is widely used and now includes statistical functionality. This paper discusses the issues raised in teaching statistics with spreadsheet software. The principal concerns relate to aspects of the spreadsheet view of computation that make it difficult to keep track of what calculations have actually been carried out or to control the spreadsheet by means of a script. We also discuss a number of other advantages and deficiencies of spreadsheets for teaching statistics.

    Abstract:
    One of the main themes of statistics courses is to teach about variability, as well as location. This is especially important for non-statistics students, who often overlook variability. We consider particularly the problem of comparing variability among k samples (k > 2) that are not necessarily drawn from Gaussian populations. This can also be viewed as testing for homoskedasticity of samples. We examine tools for this problem from the perspective of their suitability for inclusion in elementary statistics courses for students of non-mathematical subjects. The ideas are illustrated by an example that arose in a student project.

    Abstract:
    In the process of piloting and field-testing the curriculum materials, we have learned a great deal about what students and teachers understand about data analysis. We have also learned about the difficulties teachers encounter when they try to implement a curriculum which requires them and their students to respond quite differently from the way they respond in their usual mathematics classes.

    Abstract:
    This article studies various holiday distributions, the most interesting one being Easter. Gauss' Easter algorithm and Microsoft Excel are used to determine that the Easter distribution can be closely approximated by the convolution of two well-known uniform distributions.

    Abstract:
    The present paper describes a prototypical multimedia catalogue for Statistics. The catalogue represents a user-friendly organized database containing a collection of self-contained Java applets and multimedia components. It is a powerful tool which offers the option to jointly use and re-use catalogue elements across national borders and to interconnect formerly unrelated multimedia developments through sharing. In view of the costs of producing high-quality multimedia components, the systematic exchange of such modules is economically a necessity. The scope and flexibility of the approach and its suitability as a starting point for intensified international cooperation is illustrated by means of Java applets and multimedia elements originating from different environments and different content providers.

    Abstract:
    Two issues often arise in the teaching of statistical models and methods to large groups of<br>students in non-statistics programmes. Firstly, such students struggle with the relevance and the<br>applicability of the material to their own discipline. Secondly, these students struggle with the<br>notion of randomness, how to model it and how to account for it in their analyses. One approach<br>to dealing with the second issue is to expose students to as much data as possible, for both single<br>and multiple contexts, by providing individual data sets to each student for tutorial and<br>assignment work. This has been the approach taken in developing DOTS, Directed Online<br>Tutorials for Statistics, for students in engineering and the health sciences at the University of<br>Queensland. The current version of DOTS will be presented and discussed, as well as future<br>directions.

    Abstract:
    This article described three heuristics that are employed in making judgements under uncertainty: (i) representativeness, which is usually employed when people are asked to judge the probability that an object or event A belongs to class or process B; (ii) availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development; and (iii) adjustment from an anchor, which is usually employed in numerical prediction when a relevant value is available. These heuristics are highly economical and usually effective, but they lead to systematic and predictable errors. A better understanding of these heuristics and of the biases to which they lead could improve judgements and decisions in situations of uncertainty.

    Abstract:
    Teachers of judgment and decision making can be found in psychology departments, business schools, economics departments, political science departments, medical schools, engineering schools, departments of social work, and yes, other places. Therefore, it will be no surprise to learn that there are few books on this topic that are prepared for the general reader - one who wishes to be introduced to the topic without becoming fully immersed in the substantive details of any one area of application. But because the topic of judgment and decision making is of great interest to almost everyone, its applications touching almost every human endeavor, a general introduction to this topic is bound to be useful. We have included 43 chapters organized in terms of 9 areas of application. Because our aim is one of introduction, we have not included any material (with the exception of one part) that requires anything more than en elementary understanding of algebra and statistics. Each part contains a brief introduction to the material included in it.
