Final answer:
A row heading in a Crosstab query is used to categorize and organize data based on a specific attribute or field.
Step-by-step explanation:
In a Crosstab query, a row heading is used to categorize the data based on a specific criterion or category. It represents the values that are displayed along the left side of the table, forming the row headers. The purpose of a row heading is to organize and summarize the data based on a particular attribute or field.
For example, let's say you have a Crosstab query that analyzes sales data for different products over multiple years. The row headings could be the different product categories, such as electronics, clothing, and accessories. Each row would then display the sales data for each category in the corresponding columns.
By using row headings in a Crosstab query, you can easily compare and analyze the data by different categories, making it simpler to identify patterns, trends, and relationships within the data.
