To test the results of a conventional versus a new approach to the teaching of

Question

reading, 12 pupils were selected and matched according IQ, age, and present

reading ability (there are 6 pairs!). One from each of the pairs was assigned to

the conventional reading program and the other to the new reading program. At

the end of 6 weeks, their progress was measured by a reading test. Do the data

present sufficient evidence to indicate that the new approach is better than the

conventional approach at the alpha=0.05 level?
