Understanding Sample Surveys: Selective Learning about Social Science Research Methods

Resampling Methods for Sample Surveys

Application of resampling methods in sample survey settings presents considerable practical and conceptual difficulties. Various potential solutions have recently been proffered in the statistical literature. This paper provides a brief critical review of these methods. Our main conclusion is that, while resampling methods may be useful in some problems, there is little evidence of their useful...

Methods for Extreme Weights in Sample Surveys Methods for Extreme Weights in Sample Surveys

In survey sampling practice, planned and unplanned variation in the sampling weights can result in inflated sampling variances. As a result, extreme sampling weights are sometimes trimmed to reduce the sampling variance. However, when sampling weights are trimmed, a bias can be introduced into the survey estimates. The goal of sampling weight trimming is to reduce the sampling variance while av...

Understanding infants' and children's social learning about foods: previous research and new prospects.

Developmental psychologists have devoted significant attention to investigating how children learn from others' actions, emotions, and testimony. Yet most of this research has examined children's socially guided learning about artifacts. The present article focuses on a domain that has received limited attention from those interested in the development of social cognition: food. We begin by rev...

Developmental Psychology Understanding Infants' and Children's Social Learning About Foods: Previous Research and New Prospects

Understanding theory: the first step in learning about research.

This article describes a teaching method used to explain to undergraduate students how a theory is organized and how a practice model is derived based on the theory. Kielhofner's temporal adaptation of Neville's application of temporal adaptation in practice are used as examples of a developing theory and practice model. The relevance of theory analysis to research design and methods is stressed.
