er we shall look at the basic ideas underlying sampling, the different kinds of sample available, their various advantages and disadvantages, and the planning of a sampling operation. Such technical matters as calculating sample size, variability, error and bias will be touched on in Appendix 1 to tOASIS 发表于 2025-3-24 07:01:08

The main challenges appear to be related to the novelty of the topics and of the different way of thinking in these areas – very different both from classical physics (with which students have already acquired a certain familiarity) and from everyday experience.
