Introduction
Raw data, often unstructured and vast in volume, is essentially a collection of facts or observations. It lacks intrinsic value until it is processed and analysed. Data science acts as the bridge between raw data and valuable insights. It encompasses a multidisciplinary approach that combines statistics, mathematics, programming, and domain expertise to extract meaningful patterns, trends, and correlations from data.
Understanding Raw Data
Raw data can be in various forms, such as numerical, textual, or multimedia. It can come from diverse sources, including customer transactions, social media posts, sensors, or medical records. However, in its raw state, data is typically unorganized and lacks structure. It requires pre-processing and cleansing before analysis. Once transformed into a structured format, it becomes easier to gain insights and make informed decisions.
