When you have more than once source, before creating your project you need to take into account the structure of your data. This will determine whether you have to use add or append.
a) Different respondents/records across sources - Add
When respondents or cases across data sources are different, you need to add all sources into the same project. Learn more about adding data to your project.
Some examples:
- Different files across time periods (i.e. Brand Tracker_2018.sav, Brand Tacker 2019.sav)
- Different files per market (i.e. Brand Tracker_NZ.sav, Brand Tacker_Australia.sav)
Add data sources to the same project if you want to analyze them together in a single analysis or story view.
b) Common respondents/records across sources - Append
When respondents or cases across data sources are common, to include data into your project you need to append data sources. Learn more about appending data in your project.
Data append is a process that involves adding new data elements to an existing project by matching either by order or a common identifier. Append allows you to add new variables to respondents within a project when information of common respondents is captured in separate data sources.
For example, one source contains the main survey information, and another source includes the weighting variables and you need these to link together.
