A reseаrcher wаs interested in evаluating the effectiveness оf a prоgram designed tо reduce test anxiety in 1st year college students. The researcher measured all of the 1st year students at 1 college at the beginning of the year using a 50 item Test Anxiety Scale (test-retest=.35) and selected the sample of students by picking the 50 students who were the most anxious. Of the 50 students who participated in the program for 6 months, 30 students agreed to have their test anxiety measured again using the same 50 item Test Anxiety Scale. The researcher evaluated the effectiveness of the program by comparing the Test Anxiety scores at the beginning of the year to those at the end of 6 months for those students who agreed to be measured at both points in time. Define each threat and then evaluate whether this threat is relevant to the present design. 1. History 2. Statistical regression
