This paper describes where we’ve been, where we are and where we’re headed: the studies, the models, the supporting research and the systems theory-based approach encompassing the current direction.

]]>A 300-level subject covering Sample Surveys and Experimental Design has now been taught jointly to the Universities of Wollongong and Newcastle for two years, first using video-conferencing and then the Access Grid. In each year, the subject was delivered by the same two lecturers.

We provide an initial review of the subject. We discuss its organisation, the use of the technology, changes in our teaching and administrative styles needed to cope with this mode of delivery, feedback from students, and our reaction to all of these. An overview of the subject results is given.

]]>For moderate sample sizes when assuming normality the R test is nearly as powerful as the F test and nearly as robust as Levene’s test. It is also an appropriate test for testing equality of variances without the assumption of normality, and so it can be strongly recommended.

]]>The objective of this paper is to consider the development and application of a new method called Aggregate Association Index (AAI), which can be applied in such situations of gendered aggregate political data. Moreover, these two aspects of the AAI shall be examined by considering the New Zealand election data in 1893 and this may well help us establish the future development for the index.
