Loadings are sorted from center out on a per-respondent basis.weaker skills elsewhere. (See Appendix: “Non-negative Matrix Factorization”for technical details.)We can look at the T-shaped nature of the four Self-ID Groups as well.Figure 4-2 shows how strongly, on average, people in each Self-IDGroup were associated with our five Skills Groups. Data Businesspeoplewere quite T-shaped, with top skills in Business, and moderateskills elsewhere. Data Researchers tended to be very deep in Statistics(and related skills), but somewhat less broad. On average, they rankedall of the ML/Big Data, Business, and Programming skills fairly low.Data Developers had a pattern that might be called “Pi-shaped,” withstrong Programming skills and relatively strong ML/Big Data skills,along with moderate skills in the other three skill groups. And finally,Data Creatives tended to be the least T-shaped of our respondents.Interestingly, Data Creatives were, on average, neither ranked thestrongest nor the weakest in any skill group.Evidence for T-Shaped Data Scientists | 21
