“…By contamination, we mean situations in which there is an experimentally unwanted cross-exposure in interventions such as one intervention group receiving or being exposed to all or part of another intervention. One infamous example of such contamination is the report in 1931 of the Lanarkshire milk experiment (17). In this experiment, 67 schools with 20,000 students were tasked with randomly assigning students to receive a milk intervention or serve as a control within each school.…”

Cluster randomized controlled trials (cRCTs; also known as group randomized trials and community-randomized trials) are multilevel experiments in which units that are randomly assigned to experimental conditions are sets of grouped individuals, whereas outcomes are recorded at the individual level. In human cRCTs, clusters that are randomly assigned are typically families, classrooms, schools, worksites, or counties. With growing interest in community-based, public health, and policy interventions to reduce obesity or improve nutrition, the use of cRCTs has increased. Errors in the design, analysis, and interpretation of cRCTs are unfortunately all too common. This situation seems to stem in part from investigator confusion about how the unit of randomization affects causal inferences and the statistical procedures required for the valid estimation and testing of effects. In this article, we provide a brief introduction and overview of the importance of cRCTs and highlight and explain important considerations for the design, analysis, and reporting of cRCTs by using published examples.Am J Clin Nutr 2015;102:241-8.

Abstract:The purpose of methods and techniques of social research is to offer tools necessary for dealing with social problems through research in a scientific manner. The special emphasis of methods and techniques of social research arises mainly in the coverage of its materials. It contains both methods of collecting observations pertaining to social phenomena and techniques for analyzing them. The greatest advantage of having both methods and techniques within the same covers is that a researcher may easily establish a direct linkage between them and this may help greatly to choose an appropriate technique to analyze data.

“…13 These problems included not only the issue of two rather than three arms per school, but also: selection bias resulting from the quasi-random group allocation procedures; measurement bias arising from probable variation between groups in clothing; the failure to match analysis across schools; and the erroneous conclusions about the purported lack of differential of raw and pasteurized milk. Student conceded that there probably was an effect of milk on height and weight, whilst noting that ' .…”
