Exploring Data—Pattern Recognition
Data analysts employ data visualization and statistical tools to characterize dataset characterizations, such as size,
amount, and correctness, in order to better understand the nature of the data. This is known as data exploration.
Data exploration techniques include both manual analysis and automated data exploration software. These techniques
visually explore and identify connections between various data variables, the structure of the dataset, and the distribution
of data values in order to reveal patterns and points of interest, enabling data analysts to gain more understanding of
the raw data.
