Lesson 6: Creating Summary Tables
- Aggregation: a computation in which rows from a data set are grouped together and used to compute a single value of more significant meaning or measurement. Common aggregations include: Average, Count, Sum, Max, Median, etc.
- Pivot Table: in most spreadsheet software it is the name of the tool used to create summary tables.
- Summary Table: a table that shows the results of aggregations performed on data from a larger data set, hence a "summary" of larger data. Spreadsheet software typically calls them "pivot tables".
