This is the 7th survey in this ongoing research program.• CORE ALGORITHM TRIAD: Regression, Decision Trees, and Cluster analysis remain the most commonly used algorithms in the field.• THE ASCENDANCE OF R: 76% of respondents report using R. This is up dramatically from just 23% in 2007. More than a third of respondents (36%) identify R as their primary tool.• JOB SATISFACTION: Job satisfaction in the field remains high, but has slipped since the 2013 survey.

Getting organizational buy-in is the largest barrier to deployment, with real-time scoring and other technology issues also causing significant deployment problems.• TERMINOLOGY: The term “Data Scientist” has surged in popularity with over 30% of us describing ourselves as data scientists now compared to only 17% in 2013.Please contact us if you have any questions about the attached report or this research program.
