Chapter 2, Problem 24P

Forced expiratory volume (FEV) is an index of pulmonary function that measures the volume of air expelled after 1 second of constant effort. Dataset FEV.DAT at www.cengagebrain.com. contains determinations of FEV in 1980 on 654 children ages 3 through 19 who were seen in the Childhood Respiratory Disease (CRD) Study in East Boston, Massachusetts. These data are part of a longitudinal study to follow the change in pulmonary function over time in children [9],

TABLE 2.17 Format for FEV.DAT

Column

Variable

Format or code

1-5    ID number   

7-8    Age (years)   

10-15    FEV (liters) X.XXX

17-20    Height (inches) XX.X

22 Sex    0 = female/1 = male

24 Smoking status    0 = noncurrent smoker/

1 = current smoker

The data in Table 2.17 are available for each child. Use both numeric and graphic measures to assess the relationship of FEV to age, height, and smoking status. (Do this separately for boys and girls.)
