Average Measurements of 145 College Students at the Beginning of 

 Freshman Year and End of Sophomore Year 



The smaller number of observations in the physical measurements 

 is due to two causes : first, the physical examinations are optional for 

 students entering with advanced standing in physical education; these 

 students usually take only the first examination; second, a number of 

 students in this group had not yet taken their second physical exam- 

 ination when this study was made. The selection is therefore purely 

 accidental. 



It appears from these tables that there is no appreciable difference 

 between the measurements of the smokers and of the non-smokers 

 except in the matter of age. The slight advantage in the average meas- 

 urements of the smokers at the first examination is undoubtedly due to 

 the fact that they are 8 months older. The slightly larger gain made by 

 the smokers in weight, height, and total strength during the first two 

 years in college is really too small to have any significance. 



Scholarship Records of the 223 Students 



Average Marks Marks during Failures during 



at Entrance first 2 years first 2 years 



223 students 90 per cent. 66 per cent. 7 per cent. 



115 smokers 89 per cent. 62 per cent. 10 per cent. 



108 non-smokers ... 91 per cent. 69 per cent. 4 per cent. 



The differences in scholarship standing between the smokers and 

 non-smokers are distinctly in favor of the non-smokers. 



If the only difference between these two groups of students is that 

 the members of one group use tobacco and the members of the other 

 group abstain from it, then it would appear that there is a direct rela- 

 tion between smoking tobacco and scholarship. A further study of 

 these two groups brings out differences between smokers and non- 

 smokers in athletic and social activities.
