12
Be A Gremlin $100 10 A researcher is concerned that the results which he observes after an experiment might have occurred because of the composition of the group rather than from the experimental treatment, which is the most obvious threat to validity that has him concerned? 1.Selection 2.Pretesting 3.History 4.Maturation 1234567891011121314151617181920 2122232425

13
Be A Gremlin $200 Mrs. Brown has administered a test to her students to find out how well they have mastered the basic skills they will need to study her math unit. She has discovered that they are weak in some areas, and therefore she decides to provide a remedial unit to bring them up to par. She provides her remedial unit and afterwards measures the students' performance again to see if they have improved. She finds a substantial degree of improvement and therefore she concludes that her remedial unit was effective. Which of the following appears to be a threat to the internal validity of her conclusion that the remedial unit was effective? 10 1.Pretesting 2.History 3.Maturation 4.Statistical regression 1234567891011121314151617181920 2122232425

14
Be A Gremlin $300 Mrs. Smith finds that her first graders are having trouble with their basic arithmetic concepts. She therefore tries a new program and plans to evaluate them at the end of the year to see if they have made improvements. She will consider her program to be successful if the children have mastered a large number of skills at the end of the year which they had not mastered at the beginning of the year. Which of the following is the most obvious threat to Mrs. Smith's evaluation of this program? 10 1.Pretesting 2.Maturation 3.Statistical regression 4.Ceiling effect 1234567891011121314151617181920 2122232425

15
Be A Gremlin $400 Mrs. Jones is a remedial reading specialist. She has given reading screening tests to all 60 first graders at Warren Harding Elementary School. She has identified the 10 weakest readers, and now she plans to provide them with her new program of Reading Skills Development. Nine months later, at the end of the school year, Mrs. Jones plans to evaluate her Reading Skills Development Program by retesting all 60 children and seeing if her 10 remedial children improve more than the other 50. Which of the following is most obviously a threat to the internal validity of Mrs. Jones attempt to evaluate her program? 10. 1.Maturation 2.Pretesting 3.Statistical regression 4.Experimental mortality 1234567891011121314151617181920 2122232425

16
Be A Gremlin $500 Each year Mr. Brown provides a unit in his physical education class on "The Rules of International Athletic Competition." Since the present year will be an Olympics year, he decides to revise and upgrade this unit. He initiates his program to coincide with the start of the televised portions of the Winter Olympics. On the final exam, he asks his usual ten questions about International Athletic Competition. He finds that the students this year score substantially higher than the students the previous two years on the same questions. He concludes that his new program has been effective and resolves to continue it the next year. Which of the following is the most obvious threat to the internal validity of Mr. Brown's study? 10 1.Instrumentation 2.Maturation 3.History 4.Statistical regression 1234567891011121314151617181920 2122232425

17
External Excellence $100 What effect occurs when an untreated control group is determined to beat the technique evaluated in the experimental group? 1.John Henry Effect 2.Hawthorne Effect 3.Hathaway Effect 4.Hank Williams Effect 1234567891011121314151617181920 2122232425 10
