Using SPSS, analyze the data below and answer the questions. Juan made an achievement test (over 20] to measure if his students learned something about geography. He gave this test before discussions started to check what his students know and after their discussions to verify if they have learned something from their discussions. Given this situation, answer the following questions: A. What kind of reliability should Juan use to prove that his test is reliable? Why? B. Given the data below, determine if Juan's test is reliable or not. Use SPSS and include the table from your output in your answer. Explain and interpret properly. C. Which of the following students had an average performance for the pre-test? Student Pretest Post-test A 12 15 B 8 9 C 4 7 D 14 12 E 17 20 F 5 8 G 12 H 3 4 l 10 12 11 13 K 19 16 L 15 14 M 14 12 N 14 15 D 13 17 P 12 20 Q 11 18 R 10 19 S 10 15 T 3 12 U 13 V 7 14 W 9 15 X 12 8 Y 13 14 Z 15 15 AA 12 12 BB 14 15 CC 8 7 2. Pedro is trying to prove that the Genuineness scale he made is reliable. He used a Likert scale for his test ranging from 1-4 (Strongly disagree to strongly agree). Given the situation, answer the following questions: A. What type of reliability should Pedro use (Specify)? Why? B. Show the reliability estimate if Pedro uses both split-half and Cronbach alpha. Use the given the data below. Use SPSS and include the tables from your output in your answer. For split-half, use the odd-even method. Explain and interpret properly. Use the rule of thumb of reliability in interpreting C. Which item/s should Pedro remove (if there are) to increase the reliability of his test based on I. Split half II.
