Learning Data Grouping and Summarization with dplyr in R

Data analysis thrives on clarity, and achieving that often requires transforming vast tables of raw observations into concise, actionable reports. At the heart of this transformation lie two fundamental processes: grouping and summarizing data. Grouping allows us to segment a large dataset into meaningful subsets based on shared characteristics (e.g., all cars with four cylinders),
