0 Preface
Due to the need for drawing processing in many scenarios such as scientific research, the author has studied SPSS. This article summarizes the study notes through "SPSS Statistical Analysis from Beginner to Master" and its supporting materials combined with relevant online materials. This article explains the management data.
1. Decomposition of data files
(1) Known data
(2) Select the "Data|Split File" command in the menu bar, select "Organize output by group", and group by region
(3) Processing results
2. Horizontal Merge of Data Files
(1) Known data
(2) Select "Data|Merge File|Add Variable" command in the menu bar
(3) Processing results
3. Vertical Merge of Data Files
(1) Known data
(2) Select "Data|Merge File|Add Case" command in the menu bar to open the "Add Case to" dialog box
(3) Processing results
4. Transformation of data files
(1) Known data
(2) Select the "Data | Transpose" command in the menu bar to open the "Transpose" dialog box, and set the variable and name variable
(3) Processing results
5. Weighting of observations
(1) Known data
(2) Select the "Data | Case Weighting" command in the menu bar, and select the case weighting basis
(3) Processing results, weights enabled
6. Create new variables based on existing variables
(1) Known data
(2) In the menu bar, select the "Convert | Calculate Variable" command to customize the target variable
(3) Processing results
7. Generate count variable
(1) Known data
(2) Select the "Transform|Count Values in Cases" command in the menu bar, select the variable to be counted and set the count variable
(3) Processing results
8. Reassign the variable itself
(1) Known data
(2) Select the "Convert | Recode to the same variable" command in the menu bar, select the variable to be reassigned, and define the old value and new value
(3) Processing results
9. Assignment generates new variables
(1) Known data
(2) In the menu bar, select "Convert | Recode to different variables, select the variable to be reassigned, and define the old value and new value
(3) Processing results
10. Finding the level of variable value
(1) Known data
(2) In the menu bar, select the "Transform | Case Ranking" command, select the variable to be reassigned, and make corresponding settings
(3) Processing results
11. Handling of missing data
(1) Known data
(2) Select the "Transform|Replace Missing Values" command in the menu bar, and select the variable to replace the missing values
(3) Processing results
12. Aggregation of data
(1) Known data
(2) Select the "Data|Summary" command in the menu bar, select classification variables and summary variables, and make corresponding settings
(3) Processing results
13. Reorganization from variable groups to observation groups
(1) Known data
(2) Select the "Data | Refactor" command in the menu bar, select the number of variable groups, select the variables to be reorganized, select the number of variables to be indexed, set the parameters of the index variables, set other parameters, and complete the data reorganization
