Overview

Data Analysis Techniques

Data analysis techniques are statistical and machine learning methods used to extract valuable insights from large datasets and support decision-making. Various techniques exist depending on the purpose, such as regression analysis, cluster analysis, and principal component analysis, applied for prediction, classification, segmentation, and dimensionality reduction. In the modern big data era, these techniques have become essential tools across all industries including marketing, healthcare, finance, and manufacturing.
