Questions about this data
What skills do most Data Scientist job postings ask for?
Across 224 Data Scientist postings from the last 90 days, the most frequently named are Python (83%), SQL (81%), R (45%). Each percentage is the share of those postings naming the term at least once.
How common is Statistical modeling in Data Scientist postings?
Statistical modeling appears in 13% of the 224 Data Scientist postings counted — 30 of them exactly. That places it mid-pack rather than near-universal, which is worth knowing before you rewrite a résumé around it.
Where does this Data Scientist data come from?
Public job postings published by employers on their own career sites, collected through the official Greenhouse, Lever and Ashby job-board APIs. It is a count of 224 real postings seen in the last 90 days — not a survey, an estimate, or a model's guess.
Should I add these skills to my résumé?
Only the ones you genuinely have. Frequency tells you which terms to surface and phrase in the employer's own words if they are already true of you. Adding a skill you can't defend is the fastest way to fail an interview, so FreshStartr reports gaps rather than writing them in.
