Data Cleaning & Analytics  In today’s world, data is everything. Companies gather massive amounts of data every day. However, raw data is often messy, full of errors, duplicates, or missing values. This is where Data Cleaning & Analytics come into play. Data cleaning helps to refine and organize raw data, while analytics turn that clean data into valuable insights that help businesses make better decisions. In this blog, we will explore what Data Cleaning & Analytics are, why they matter, and how they can transform raw data into meaningful business insights. What is Data Cleaning & Analytics?

When businesses collect data, it often contains errors due to human input, system glitches, or outdated information. Cleaning the data ensures that it is accurate, reliable, and useful for analysis. Some key steps in data cleaning include: Removing duplicates – Ensuring that the same data entry is not recorded multiple times. Handling missing values – Filling in or removing missing information to ensure completeness. Correcting errors – Fixing typos, incorrect values, or inconsistencies.
