About
Data analysis is a critical discipline that enables organizations and individuals to make informed decisions based on empirical evidence rather than intuition. The process begins with data collection, where raw data is gathered from various sources such as databases, surveys, or sensors. This data often comes in unstructured or semi-structured forms, requiring preprocessing steps like cleaning, where errors, duplicates, and irrelevant information are removed. Data transformation is the next stage, involving the conversion of data into a suitable format for analysis, which may include normalizing or aggregating data points.
