Final answer:
The statement that groups can only be created with data from individual tables is NOT true; groups can involve data from multiple related tables. Grouping is facilitated by tools like the Report Wizard and helps create summaries augmented by visuals like bar graphs.
Step-by-step explanation:
Among the statements provided regarding the creation of groups in a report, the one that is NOT true is that "Groups can only be created with data from individual tables." This statement is incorrect because grouping in reports can often involve data from multiple tables, especially when these tables are related through keys or when a query is designed to fetch and combine data from multiple sources. It is possible to create groups based on joint queries that involve several tables.
When organizing and summarizing data in reports, the Report Wizard indeed provides options to group data, and a group is essentially a collection of records along with introductory and summary information about them. Grouping helps to create a visual summary of the data, aiding in its interpretation, which can be further enhanced with the use of graphical tools such as bar graphs and pie charts. Bar graphs, for instance, are particularly useful for comparing quantities and showing relationships between data points like populations of different countries or other categorical data.
