Sample Size Still Matters
"Stand at the door of a church on a Sunday and bid 16 men to stop, tall ones and small ones, as they happen to pass out when the service is finished; then make them put their left feet one behind the other, and the length thus obtained shall be a right and lawful rod to measure and survey the land with, and the 16th part of it shall be the right and lawful foot." - Jacob Koebel 16th century
Does a sample size of 16 have the statistical power for credible assignment results?
If the sample distribution is normal, a minimum sample size of 15 is required. A normal distribution will have equal mean, median and mode.
If the sample distribution is non-normal, a minimum sample size of 30 is required.
