Science in a minute - What's a random sample
Institutional Communication Service
21 March 2022
A "random sample" is selected completely at random from members of the population, to represent it. This episode discusses the criteria by which it is chosen and the difficulties that may be experienced during the selection process.
The Science in a Minute project carries on. Promoted by the Swiss School of Public Health, it aims to provide, through a series of short videos, some of the answers to the most frequently asked questions about scientific facts and topics related to public health in order to make them clear and accessible to everyone.
Dr Rebecca Amati, project manager of the Corona Immunitas Ticino project, guides us on this path, explaining complex concepts and processes in layman's terms. The series is constantly updated according to the evolution of the pandemic. A weekly one-minute clip tackling a different topic will be available.
