95% of Data Science Success Requires Only Basic Math Skills

A self-taught data scientist with a mechanical engineering background shares insights into the reality of data science skills. Despite working with highly educated colleagues, this individual ranks second in productivity, not due to superior technical ability, but through practical experience and domain knowledge. The article highlights that only a basic understanding of calculus, statistics, linear algebra, and probability is necessary for most data science tasks. For instance, understanding derivatives and integrals at a fundamental level suffices for calculus. In statistics, knowing what a p-value represents is more crucial than mastering all statistical tests. The key to success lies in the ability to test and evaluate models effectively, rather than in-depth knowledge of every algorithm or mathematical concept. The author emphasizes that practical experience, like data exploration and domain knowledge, often trumps advanced technical skills. This perspective challenges the common industry narrative that one must be an expert in numerous fields before starting in data science.
