Data Analysis Technique RESEARCH METHODOLOGY

30 the surface structure taxonomy, the comparative taxonomy, and the communicative taxonomy. The classifications of the surface structure taxonomy were omission, addition, misformation, misordering. The classifications of the comparative taxonomy were developmental errors, interlingual errors, ambiguous errors, other errors. The global errors and local errors were the communicative taxonomy. There were 117 utterances containing the verb phrase errors. The researcher found that there were at least two verb phrase errors in each utterance. The list of errors can be seen in Appendix C. There were 355 verb phrase errors occurring in the participants‟ speech. The number of the verb phrase errors can be seen in Table 4.1 and Figure 4.1.

The researcher determined the groups considering the fluency of the participants. Besides the fluency, the researcher also looked to the way they delivered their speech for example the nervousness and the speed of the speech. The participants who were not fluent and they were nervous; they belonged to the low level group. In contrary, the participants who were fluent and they were not nervous; they belonged to the high level group. The first group consisted of four participants who had the high level in speaking. There were 148 verb phrase errors which were found in those participants‟ speech. The Table 4.2 showed the errors made by the high level students. From the table, the most error that the high level group made was the local error as many as 37 and they made few ambiguous error i.e. 2 errors. 17.46 7.89 5.35 2.82 18.87 6.2 2.25 6.2 7.32 25.63 Omission Addition Misformation Misordering Developmental Errors Interlingual Errors Ambigous Errors Other Errors Global Errors Local Errors 32 Table 4.2: The High Level Students’ Errors Num.

The most error that the low level group made was the local error as many as 54 errors. The participants made few misordering as many as 5 errors. The low level students‟ errors are showed in the Table 4.3. Table 4.3: The Low Level Students’ Errors Num. Surface structure Comparative Communicative Omis. Add. Misf. Misor. Dev . Inter. Am b. Oth.
