Abstract:

The aim of the research was to determine the differences students inductive reasoning skills from different grades. The research was a cross-sectional study using instruments from an online test from the eDia platform consists of 53 items to measure the numerical and figurative inductive reasoning skills. The sample was taken randomly. The data were collected from 61 students in Indonesia, 28 students from grade 8th and the rest from grade 11th. The result of data analysis shows that there are differences of inductive reasoning skills of students in different grades. In this case, students from the higher grade have better abilities than a lower grade. Furthermore, the significant differences can be found in the form of the numerical inductive reasoning between the grades (M_NIR_GR8 = 45,33; M_NIR_GR11 = 67,13; p<0,05) and also the numerical and figurative inductive reasoning skill within the grades (p<0,05). On the other hand, there was no difference of students figurative inductive reasoning skill between the grades(M_FIR_GR8 = 72,09; M_FIR_GR11 = 79,80; p>0,05). It can be concluded that the inductive reasoning skill is developed through the grade of the students.
