Suppose a researcher wants to see whether teaching students to read using a computer game gives better results than teaching with a tried-and-true phonics method. She randomly selects 20 students and puts them into 10 pairs according to their reading readiness level, age, IQ, and so on. She randomly selects one student from each pair to learn to read via the computer game, and the other learns to read using the phonics method. At the end of the study, each student takes the same reading test. The data are shown in the following table.

Question

Suppose a researcher wants to see whether teaching students to read using a computer game gives better results than teaching with a tried-and-true phonics method. She randomly selects 20 students and puts them into 10 pairs according to their reading readiness level, age, IQ, and so on. She randomly selects one student from each pair to learn to read via the computer game, and the other learns to read using the phonics method. At the end of the study, each student takes the same reading test. The data are shown in the following table.

Student Pair	1	2	3	4	5	6	7	8	9	10
Reading Score under Computer Method	85	80	95	87	78	82	57	69	73	99
Reading Score under phonics method	80	80	88	90	72	79	50	73	78	95

Test whether there is a significant difference between the computer method and the phonics method. If there is a significant difference, which particular method is better?
