A "data slice" refers to a specific subset of data extracted from a larger dataset. This process allows analysts to focus on particular variables or time periods, making it easier to analyze trends or patterns. For example, a company might create a data slice to examine sales figures for a specific product line during a particular quarter. Data slicing is commonly used in fields like data analysis, business intelligence, and machine learning. By isolating relevant data, organizations can make informed decisions based on targeted insights, improving their overall strategy and performance.
