Students' previous computing experience was considered for its potential impact on attitudes toward omics data analysis, as well as students' racial identity, gender, and socioeconomic status. The analysis indicates that students benefit from being exposed to computer programming prior to taking the course, as this previous experience broadly shaped their confidence with using omics data. However, there were also significant nuances to this trend regarding students' racial and gender identities. Further, despite these differences, students' attitudes toward omics did not affect final test scores. In the following paragraphs, we discuss the variables that have the most significant differences among the primary cohort that impacted attitude towards coding and omics data.
