I need to know how I can select/aggregate equal attributes in a table.
This is quite the same I want to do. But I want to do it with the modeler. How to group and count attribute data?
The column "Number" has attributes like 1.1 or 1.3 or 4.3. There are a lot of 1.1 or 1.3....in the column. In step1 I want to find all the 1.1 or 1.3 ...for calculating later the weighted average of a value by using the area. The problem is that the "Numbers" are different in all my tables. In EXCEL I could use a data filter to select all the equal attributes. Its not easy to describe...sorry. To say it in one sentence: If „Numbers“ are equal than calculate the weighted average of the Values and create a new table
But hopefully the screenshot describes the problem better than my words.
