Re: Conference of the Monarch (Thoughts)
You introduced a LOT of bias into your sample.

1. You used only one point in time. It is unlikely that this is representative of the activities of all pirates. You should have sampled multiple times over different times of the day and days of the week.

2. You sampled only pirates on ships. The stats of the pirates in your sample are therefore biased towards the type of voyages out at the time.

3. You sampled from one archipelago only. The activities in different archipelagos can be vastly different at any given time.

4. You got bored and stopped collecting data half way through a frig. If this had been a SMH your results would have been very different had you completed the entire ship.

Your sample was in no way representative of the population of pirates. If you were to come up with a sensible sampling scheme to address the biases above, your results would be worth looking at but as they stand, they are meaningless.

The only time you considered potential bias, you were wrong. No bias can be introduced by checking ships in alphabetical order since ships are named randomly.
