Demographic Data 



Only a few demographic variables will be listed in this report. There is still a large ar- 

 ray of interest and attitude measures to be analyzed. Tables and brief comments below are 

 given for the variables of age, years of diving experience, education, marital status, size of 

 home town, civilian/military status, and career commitment. Breakdowns are given for the 

 entire group and for each team. There were ten men on each team, but only 28 in the total 

 group, since two men were in two crews. 



Age —Data on age are presented in Table 20. The numbers in the table represent the 

 numbers of men in each age category. Mean age and age range is given below.

It is perhaps not surprising that the mean age of the group is over 35 and that nearly half 



the men are in the 35-to-39

 It is no doubt for the same reason, experience as a criterion in

 Everest climbing team. Both these groups have mean ages in the 



Although mean ages of the three teams are quite similar, there are differences in the 

 range, with Team 2 having markedly less variation in age range than Teams 1 and 3. Since 

 Team 3 had among its members the oldest man in the group, by six years, the mean age does 

 not fully reflect how miich younger this group was than were Teams 1 and 2. 



Experience — As a group, the aquanauts averaged nearly eleven years of diving experience 

 (Table 21). It is interesting to note that, while Team 3 was the youngest group, its members 

 had the most diving experience. This is true despite the fact that for all team members there 

 was a correlation of about 0.70 between age and diving experience.
