After entering the data, you can first perform basic data statistics - descriptive statistics. Then based on your data results, see whether correlation regression or other analysis is needed. The descriptive statistics in spss are mainly in analyze-descriptive, which includes descriptive statistics, frequency statistics, and cross analysis.
Descriptive statistical analysis is the first step in statistical analysis. Select analyze first, and you will see descriptive, and then select Descriptive with the mouse. In the menu, the four most commonly used processes are listed at the top: the Frequencies process is characterized by generating frequency tables; the Descriptives process performs general statistical descriptions; the Explore process is used for exploratory analysis when the overview of the data is unclear; The Crosstabs process completes the statistical description and general statistical testing of count data and grade data.
Choose Analyze first, --- then choose descriptive
After opening any analysis window, you can select the data you want to analyze. You can press the left button of the mouse together to select and press the middle button to join. Then select and click to pop up the Statistics dialog box, which is used to define other descriptive statistics that need to be calculated.
