A Data Scientist uses mathematics, statistics, and programming to analyse complex data and turn it into useful insights. They help organisations make data-driven decisions in areas such as finance, technology, healthcare, and business. Data Scientists work with large datasets, build predictive models, and communicate their findings clearly to teams and decision-makers.
