and only 16.6 per cent, of the non-smokers obtained places on the varsity teams. It is clear from the above that the concluding sentence means nothing unless the number of smokers and of non-smokers contesting is given.
The conclusion that smokers stand but little chance with nonsmokers in obtaining places on football squads is not only shown by the total of the six institutions, but is similarly shown in each of the six. It should be observed here that the introduction of data from a single institution departing radically from the general trend of all others would influence very largely the average of the total. In such a case the average would be wholly unreliable. But in the case at hand where not only the total of the six institutions point in a given direction, but also each of the six, the average very closely approximates the truth.
The following table shows the inferiority of the smokers in each of the six institutions reporting:
|Institution A.||Number Competing
- It will be noted that no smokers obtained places on this team. In consequence of this the data from this institution are not used elsewhere in this investigation.
