This article presents a profile of students statistical reasoning ability on the topic of inference statistics based on their academic characters. Data was collected from active students of pre-service mathematics students in the even semester of 2018/2019 that consisted of two learning classes. Based on the similarity of the statistics pretest result, one class was determined randomly as the experimental group and the other class as the control group. Statistical reasoning ability (SRA) and prior knowledge of statistics (PKS) were measured by test instruments. Student characters data were collected through a closed questionnaire. Each students academic character was explained by the association with nine PKS indicators. Based on the age, students were aged from 19 - 21 year and consisted of 29% of male and 71% of female. The PKS profile based on gender showed that female students tend to have higher SRA achievement for each indicator than male students. Students in the experimental group with more frequent learning intensity and longer learning periods tended to show better achievement of PKS compared to students in the control group. Students with low and high PKS levels indicated that the students- SRA achievement in the experimental group tended to be better than students- SRA achievement in the control group while the moderate level was not.
