Table 6.08: Question 8 – Paper-Based Pretest and Posttest Score Comparison Student# Student Code. Q8 (Pretest score, worth 15 points) Interpretation (Question 8): Students’ average score for this question was 2.83 in the pretest and 12.51 in the posttest. This means that on an average, the students scored very poorly (18.86%) on this question in the pretest. But the average score improved significantly to 83.4% in the posttest. The standard deviation of the scores was 2.53 and 3.17 in the pretest and posttest, respectively. This means that the deviation in the scores from the average actually increased from the pretest to the posttest. This is because student JL711S2 scored zero on this question in both the pretest and posttest, whereas the others improved significantly in the posttest. 92 Q8 (Posttest, worth 15 points) Experiment 1 1.

Question 9 (15 points): • Test A: ZLTech has a Web-based student records system. A student has to enter his or her Social Security number in the text field provided for it and then click on the sign in button to log in and access his or her records, which include courses taken by the student so far and the corresponding grades. The Social Security number can have only 11 characters. The first three characters have to be digits, then a hyphen and then two more digits, a hyphen and finally four digits. No other characters whatsoever are allowed to be entered for the Social Security number field. What variables could be involved in analysis of this group of facts? What variable do we know enough about to perform equivalence class analysis and then a boundary value analysis? Develop a series of tests by performing equivalence class analysis and boundary value analysis on this variable. • Test B: The U.S. Immigration and Naturalization Service has an online application that lets international students check the status of their work authorization application in the United States. Upon applying for work authorization, every student is given a ticket number, which is an 11- character value. Every ticket number consists of digits and uppercase letters, with a letter in the fourth and eighth positions. The other characters have to be strictly digits. What variables could be involved in analysis of this group of facts? What variable do we know enough about to perform equivalence class analysis and then a boundary value analysis? Develop a series of tests by performing equivalence class and boundary value analysis on this variable. Table 6.09 analyzes and interprets learners’ scores on Question 9. 93
