Forced Expiratory Volume (FEV) Data

Description

Data from: Fundamentals of Biostatistics Notes from: Kahn, M.

Abstract

Sample of 654 youths, aged 3 to 19, in the area of East Boston during middle to late 1970's. Interest concerns the relationship between smoking and FEV. Since the study is necessarily observational, statistical adjustment via regression models clarifies the relationship.

Pedagogical Notes:

This is a versatile dataset that can be used throughout an introductory statistics course as well as an introductory modeling course. It includes many issues from statistical adjustment in observational studies, to subgroup analysis, quadratic regression and analysis of covariance.
