Suppose a Pilot Study Tells You That There Is a Great

Multiple Choice

Suppose a pilot study tells you that there is a great deal of natural variability in the population.How will this impact the design of your actual, full blown study?

A) It will cause you to take a larger sample than you may have originally planned on.
B) It will cause you to abandon the bigger study; you won't be able to detect any differences or relationships even if they did exist.
C) Since there is so much variability, you might as well use a smaller sample size, because smaller sample sizes have more variability as well.
D) The pilot study shouldn't impact your design at all; that would be 'data snooping.'
