Any business, especially those that are data-driven, will expect a Data Scientist to understand the different approaches to statistics — including maximum likelihood estimators, distributors, and statistical tests — in order to help make recommendations and decisions. Calculus and linear algebra are both keys as they’re both tied to algorithms. machine learning #2. Analytics and Modeling Data is only as good as the people performing the analytics and modelling on it, so a skilled Data Scientist is expected to have high proficiency in this area. Based on a foundation of both critical thinking and communication, a Data Scientist should be able to analyze data, run tests, and create models to gather new insights and predict possible outcomes. #3. Machine Learning Methods While having expert level knowledge in this area isn’t always necessary, a level of familiarity will be expected.
