Chapter 6: Results and Their Analyses 6.01 Experiment Pretest and Posttest Results This section presents the results of evaluation of the pretest and posttests (both paper-based and computer-based performance test). The results have been analyzed and interpreted. • The scores for individual questions, the final scores of all the 23 learners and the interpretation of the scores are presented in Table 6.01 to Table 6.10. • The graphic representation of the comparison of the 23 learners’ final scores is presented in Chart 6.01 to Chart 6.03. • The average of pretest score, posttest score and percentage increase for the 23 learners is presented in Chart 7.12. 6.01.01 Paper-Based Pretest and Posttest: Results and Their Interpretation All the learners’ scores are presented in Table 6.01 to Table 6.10. Question 6, which tested all pairs combination, had an experimental error corresponding to Experiment 1. This has been discussed in section 5.06. This question, which was worth 10 points, has not been evaluated for Experiment 1. Consequently, the paper- based pretest and posttest for Experiment 1 are evaluated out of a total score of 90 points and those for Experiment 2 are evaluated out of 100 points. Before we proceed to the results, let us look at the definitions of the terms “average” and “standard deviation.” Average: “An average is a numerical value used to describe the overall clustering of data in a set. Average is usually used to indicate an arithmetic mean. However, an average can also be a median or a mode” (Intermath Dictionary, 2004a, 1). 76
Standard Deviation: “A measure describing how close members of a data set are in relation to each other. The standard deviation is the square root of the variance, also known as the mean of the mean. The standard deviation can be found by taking the square root of the variance” (Intermath Dictionary, 2004b, 1). Question 1 (10 points): • Test A: An integer field/variable i can take values in the range –999 and 999, the endpoints being inclusive. Develop a series of tests by performing equivalence class analysis and boundary value analysis on this variable. Analyze only the dimension that is explicitly specified here. • Test B: An integer field/variable i can take values in the range –1000 and 1000, the endpoints being exclusive. Develop a series of tests by performing equivalence class analysis and boundary value analysis on this variable. Analyze only the dimension that is explicitly specified here. Table 6.01 analyzes and interprets learners’ scores on Question 1. 77
