How to group data in SPSS? Tutorial on how to group data in SPSS

How to group data in SPSS? Many users are asking this question? Let's come to the editor to take a look at the operation tutorial of data grouping in SPSS. Friends who need it can refer to it.

Group distance grouping: When there are many variable values, data grouping uses group distance grouping, which means that all variable values ​​are divided into several intervals in sequence. Two questions:

Determination of the number of groups: It is related to the characteristics of the data itself and the number of data. The principle of determining the number of groups is that the characteristics and rules of data distribution can be clearly displayed. If the number of groups is too few, the data distribution will be too concentrated. If the number of groups is too many, the data will be too scattered. The number of groups should be determined according to the formula proposed by Sturdes.

Determination of group distance: Divide the difference between the upper limit and lower limit of the group by the number of groups to determine the group distance.

The examples are introduced, divided into 4 groups, and the operation is shown in the picture. Call up the relevant operation interface.

​​Select "Old Values ​​and New Values" in the window. In the interface that appears, the old values ​​are classified into new groups according to certain rules. Explain the first picture: Divide the numbers from the smallest to 10 in the old values ​​into a new group, and the phrase code is 1. Don't forget the rules formed by the "Add" button; the explanations for other pictures are the same.

In "Output Variables", "Name" and "Label" are the names of new variables after classification.

The final classification situation is shown in the variable name "fzh". The picture range is limited and only shows the first group of situations after classification.

The above explains the detailed steps for grouping data in SPSS. I hope friends in need can learn it.
