What is data science in simple words? Data Science is a multidisciplinary field that uses scientific methods, algorithms, and systems to extract insights and knowledge from structured and unstructured data. It involves analysing and interpreting data using techniques such as statistics, machine learning, and data mining to make informed decisions or predictions. Essentially, data science is about turning raw data into actionable insights that can be used to solve real-world problems and improve business outcomes. What does data science actually do? Data science is a field that involves using various techniques, tools, and algorithms to analyse, interpret, and derive insights from data. The primary goal of data science is to extract meaningful insights from data that can inform decision-making and drive business outcomes. Data science involves a range of activities such as data collection, data cleaning and preprocessing, data analysis, data visualisation, and predictive modelling. These activities require a combination of skills from various fields such as statistics, mathematics, computer science, and domain-specific knowledge.
