Suppose a researcher examined 100 possible relationships between the different measurement variables in her study, and found five of them to be statistically significant. Would these five statistically significant relationships have been more, less, or equally meaningful if they had been the only five relationships that were examined in her study?

Question 2

Explain why 5 of all relationships that occur by chance alone will erroneously earn the title of being statistically significant.'

Answer to Question 1

THESE FIVE RELATIONSHIPS WOULD HAVE BEEN MORE MEANINGFUL IF THEY HAD BEEN THE ONLY FIVE EXAMINED. SINCE 5 OF ALL RELATIONSHIPS OCCURRING BY CHANCE WILL BE FOUND TO BE SIGNIFICANT, AND 5 OUT OF 100 IS 5, THE RESULTS SHE HAS NOW ARE NOT VERY MEANINGFUL.

Answer to Question 2

THAT IS THE PRICE WE PAY FOR NOT BEING ABLE TO MEASURE THE ENTIRE POPULATION -- WHILE STILL BEING ABLE TO DETERMINE THAT STATISTICALLY SIGNIFICANT RELATIONSHIPS DO EXIST.
