<![CDATA[The rapid development of Artificial Intelligence (AI) has encouraged its use as a supporting tool for research data processing. This study aims to compare the performance of ChatGPT and Gemini in processing and analyzing student learning outcome data using SPSS as the validation reference. A comparative research method was employed using pre-test and post-test data from 25 students. The data were analyzed to calculate Gain and Normalized Gain (N-Gain) values in SPSS, and the results were compared with outputs generated by ChatGPT and Gemini using identical prompts. The findings indicate that both AI platforms produced Gain and N-Gain values consistent with SPSS, with the only difference being the rounding of the average N-Gain value (0.63 compared to 0.6321 in SPSS). Therefore, ChatGPT and Gemini demonstrate equivalent accuracy and have potential as supporting tools for educational data processing, although validation using statistical software remains essential.]]>
