A series of Kruskal Willis H tests revealed students coming from working class families were the least likely group of students to have previous research experience with extensive data analysis (see Table 11.4, 12). At pre-test, students from working class families were more likely to be taking the course to gain skills that would help them get into omics data research than their peers (Table .1). After the course, there were no significant differences between students' involvement with research based on socio-economic class (Table .2).
