Introduction: Data Science is an interdisciplinary field that uses scientific methods, statistical techniques, algorithms, and computer systems to extract meaningful insights from structured and unstructured data. With the rapid advancement of digital technology, organizations today generate massive amounts of data through websites, mobile applications, sensors, business transactions, and social media platforms. This data contains valuable information that can support effective decision making. In traditional organizations, decision making was mostly based on human intuition, experience, or limited historical records. However, such decisions were often subjective and sometimes inaccurate. Data science provides a more reliable and evidence-based approach to decision making by analyzing large datasets and identifying hidden patterns or relationships. The field of data science combines several disciplines including statistics, machine learning, data mining, big data analytics, and data vi...
