How to do SPSS AggregateProgrammers and students who want to know how to aggregate data in SPSS can certainly do themselves a favor by taking a look at our professional guide.

Working with SPSS aggregate information is an excellent way to summarize multiple observations. This generally works when processing data that is currently stored in a long format. If the data file in question contains several rows on each subject and a summary of multiple different observations into a single data line is desired then this system will end up working. Remember that this works with averages and therefore may end up being considered loss-ridden by those who require a certain level of high precision. Sometimes those who need to sort by string values will find this method to be lacking and might want to try an alternative approach instead. In addition, you may know more about few basic steps to using SPSS for data analysis that will help anyone working with the software to really speed up the process.

Data Aggregation Solutions

When making aggregate data with the SPSS platform its important to keep the following lists of steps in mind to avoid any problems:

1) Go to the Data tab.

2) Select Aggregate from the list of options to be gin the process.

3) Wait for the Aggregate window to pop up and then enter the ID into the box that’s marked Break Variable.

4) Navigate to the Summaries of Variable heading and then enter the other pieces of information there. The amount of data that needs manual entry here usually depends on how many different levels of observations are required by the long format data.

5) Approve the changes and give the program time to process it. On most modern systems this should be nearly instantaneous.

Keep in mind that the break variable is the variable that a summary is desired from. When trying to aggregate numeric variables together the program tries to calculate a mean by default. The program will keep the first observation of each subject if a string aggregate is instead selected.

Custom Aggregate Data

Those who don’t care for the way that the software creates an aggregate data table in SPSS by default can change these functions. Click on the Function menu and head over to the default summary operations list. Each one provides the user with some functions to change around. The names and labels of each option can also be changed here if there were any problems with them. This is especially important for those who are printing out reports.
