It finds data science is the most mixed and confusing role in the data/AI space, splitting roughly into two types: analytics data scientists (54%, focused on statistics, AB testing, Tableau) and machine learning data scientists (46%, focused on model building, deployment, PyTorch, TensorFlow, and increasingly LLMs/agent systems). About 19% of ads labeled 'data scientist' are actually for other roles. Degree requirements are higher than other data roles (72% mention a degree, but only 2% require a PhD). The video ends with a proposed learning roadmap covering Python, SQL, statistics, math, machine learning, relevant libraries, cloud platforms, and portfolio projects, alongside a promoted DataCamp partnership. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What percentage of data scientist job ads actually require a PhD degree? Only about 2% of data scientist job ads actually require a PhD, even though 32% mention a PhD as a preferred qualification. Overall, 72% of data scientist ads mention some degree (32% PhD, 25% master's, 14% bachelor's), compared to 40-50% for other data roles, while 28% mention no degree at all. _Developers weighing further study against job requirements can track roadmap breakdowns like this on daily.dev._ ### What is the difference between an analytics data scientist and a machine learning data scientist? An analytics data scientist answers advanced business questions using statistics and math, relying on skills like AB testing and Tableau, without building production models. A machine learning data scientist builds models from scratch, such as recommendation systems, and deploys them into live production environments, with growing emphasis on LLMs and agent systems, mentioned in nearly half of related job ads. _Anyone mapping out a data science specialization can follow role comparisons like this on daily.dev._ ### What percentage of data scientist job postings are actually mislabeled and not real data science roles? At least 19% of job ads labeled data scientist are actually for different roles, including data analyst, AI researcher, BI developer, data engineer, or product manager positions. Many companies write data scientist on the title even when the actual project work is data engineering, so candidates are advised to clarify expectations during interviews. _Job seekers sorting real data science roles from mislabeled postings can dig into findings like this on daily.dev._ ## Similar posts on daily.dev - [Data Science in 2026: Is It Still Worth It?](https://daily.dev/posts/data-science-in-2026-is-it-still-worth-it--4fl4dwcng) · Towards Data Science · 1 upvotes · 0 comments - [Top 5 Takeaways to Find Yourself in the Future of Data Science](https://daily.dev/posts/top-5-takeaways-to-find-yourself-in-the-future-of-data-science-sy0h1qub6) · Cisco · 0 upvotes · 0 comments - [Uncovering Data Science: Skills, Careers and Education](https://daily.dev/posts/uncovering-data-science-skills-careers-and-education-6ovxfqh2y) · databricks · 0 upvotes · 0 comments --- Tags: [#machine-learning](https://daily.dev/tags/machine-learning), [#python](https://daily.dev/tags/python), [#data-science](https://daily.dev/tags/data-science), [#career](https://daily.dev/tags/career) [View this post on daily.dev](https://daily.dev/posts/data-scientist-roadmap-built-from-40-000-real-job-ads-6kz31gsec) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Data Scientist Roadmap: Built From 40,000 Real Job Ads","url":"https://daily.dev/posts/data-scientist-roadmap-built-from-40-000-real-job-ads-6kz31gsec","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/data-scientist-roadmap-built-from-40-000-real-job-ads-6kz31gsec"},"datePublished":"2026-09-29T12:06:34.659Z","dateModified":"2026-09-29T12:07:05.117Z","description":"Based on analysis of nearly 40,000 real job ads from over 10,000 companies, the video breaks down what companies actually expect from data scientists.
