Abstract

The purpose of this study was to analyze students’ commognitive activities during discussion sessions in solving skewness and kurtosis problems. The research method used was descriptive qualitative research involving third-semester students at the State University of Malang in the 2020–2021 academic year. Based on the analysis of the completion of LKM 1 and LKM 2, all 17 groups had not yet fulfilled the commognitive components. Therefore, several groups were randomly selected, namely Group 1 and Group 15, as research subjects. The results showed that Subject Group 1 (SK1) did not interpret the final results and also failed to reflect the skewness and kurtosis curves. Meanwhile, Subject Group 15 (SK15) made errors in writing the symbols for the range, did not describe the skewness and kurtosis curves, and made mistakes in writing the formulas for the measures of location Q1 and Q3. In addition, SK15 also made errors in applying the formula to determine the kurtosis value.
