Description: This table of summary stats on the 1970 Vietnam Draft Number Lottery shows the mean draft number for the earlier months in the year (Jan, Feb, March) are much higher than the mean draft number for the later months of the year (Oct, Nov. Dec). Run a linear regression on the month no vs. mean draft number for each month to see that the later months of the year had lower draft numbers (NOTE: a lower draft number where the first to be drafted)
Conclusion: The little blue capsules that held the 366 calendar birthdates were not thoroughly mixed in the drum before selection began. The last months added to the bin (Oct, Nov, Dec), where more likely to be selected early.
