  Students were randomly assigned to conditions, and the following group means were found (where higher means reflect better performance):
   Teaching Method
   New Old
  Expectation that method works 25 15
  Expectation that method does not work 15 5
 
   Assuming that all of the differences are statistically significant, what can the researcher conclude?
   a. The old teaching method is more effective.
   b. The condition with the expectation that the method does not work performed better.

   performed the best.
   d. Expectations did not have an impact on student performance.
