Pivot table意思

"Pivot table" is a term used in data analysis and spreadsheet software, such as Microsoft Excel, to describe a tool that allows you to summarize and manipulate large datasets by organizing them into rows and columns.

A pivot table can help you extract meaningful information from a large dataset by allowing you to:

  1. Group data: You can group data by certain categories, such as month, product type, or region, to get an overview of your data.

  2. Summarize data: You can summarize the grouped data using various functions, such as sum, average, count, maximum, or minimum.

  3. Slice and dice data: You can rearrange the structure of the pivot table to view the data from different perspectives, which is particularly useful for analyzing trends and relationships within the data.

  4. Filter data: You can filter the data to focus on specific subsets of your dataset, which can help you identify anomalies or trends that might be hidden in the overall data.

  5. Reaggregate data: You can change the way the data is summarized at any time, which allows you to explore different aspects of your data without having to create multiple spreadsheets or formulas.

Pivot tables are especially useful for business intelligence and reporting, as they allow non-technical users to quickly analyze and understand large datasets without the need for complex SQL queries or data manipulation languages.
