spss22.0

spss22.0 official version is a professional and powerful data analysis tool. The Chinese version of spss22.0 is built with the top scientific computing engine, providing users with data mining, analysis and decision-making solutions, suitable for natural sciences, technical sciences and other fields. Through spss22.0 software users can directly analyze various data in the database and detect some errors in the project.

spss22.0 function introduction

1. spss22.0 continues IBM's blue style (starting from version 19.0). After opening in the window, there is a relatively comprehensive dialog box. Although it is similar to before, it is basically more comprehensive and more humane. ization tutorial. ps: This is very similar to SAS and R.

​​ 4. Similar to versions such as 21.0, several utility programs are provided for download. The advantage of this extension is that it can make this previously closed data processing system more open to more diversified R and general programming languages ​​such as Java. Although at this stage, most of us will no longer use spss to operate, but will directly build the database ourselves and find more economical analysis software.

5. The help window can directly open the web version of the tutorial, which is more visually friendly.

   2. How to import excel data into spss?

When the amount of data is small and copying is convenient, we can directly copy its content to the data view.

Specific operations:

After editing the variables, copy the data in excel, then switch to the data view, right-click and paste it OK

​ ​​Importing files: After becoming more proficient in using spss, we can directly import the data in the document, including variable names, etc. can be imported directly.

Operation steps: File-Open-Data. Then find the excel file you want to open and open it

      3. How to analyze data with spss?

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. You can analyze mean, median, mode, sum, etc. Then you can also click the Charts dialog box and select histograms, pie charts, etc. to draw. After everything is confirmed, click the Continue button and then select OK. That's it. There will be output directly.

You can first look at the results of descriptive statistics to see if there are any missing values ​​or unrealistic data. If so, you need to correct the data and analyze it using descriptive statistics.
