Summary: DataAnalysis focuses on extracting meaningful insights from raw data using statistical and analytical methods, while data visualization transforms these insights into visual formats like graphs and charts for better comprehension. Is DataAnalysis just about crunching numbers?
Summary: The Data Science and DataAnalysis life cycles are systematic processes crucial for uncovering insights from raw data. From acquisition to interpretation, these cycles guide decision-making, drive innovation, and enhance operational efficiency. DataCleaningDatacleaning is crucial for data integrity.
Introduction Are you struggling to decide between data-driven practices and AI-driven strategies for your business? Besides, there is a balance between the precision of traditional dataanalysis and the innovative potential of explainable artificial intelligence.
DataCleaning: Raw data often contains errors, inconsistencies, and missing values. Datacleaning identifies and addresses these issues to ensure data quality and integrity. Data Visualisation: Effective communication of insights is crucial in Data Science.
The following figure represents the life cycle of data science. It starts with gathering the business requirements and relevant data. Once the data is acquired, it is maintained by performing datacleaning, data warehousing, data staging, and data architecture. character) is underlined or not.
