Suppose researchers tell you that they did not find a statistically significant relationship between two variables, and the p-value was .84 . Which of the following must be true?
 a. The sample size must have been small.
  b. There must not be a relationship in the population.
  c. There must not have been a relationship observed in their sample.
  d. None of the above.

Question 2

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.'
