SPSS FAQ

Analysis of Variance (ANOVA) requires that the variances of each group are uniform, but it is generally believed that if the number of people in each group is similar, even if the variance test fails, it will not be a big problem.

In the One-Way ANOVA dialog box, click the Options... button and check Homogeneity-of-variance. It will generate Levene, Cochran C, Bartlett-Box F and other test values ​​and their significance level P value. If the P value is <0.05, the hypothesis of neat variance is rejected.

By the way, the Cochran and Bartlett test is quite sensitive to non-normality. If the test result of "rejection of neat variance" occurs, it may be made for this reason.

How to convert SPSS result files (*.spo files) to other formats?

The result file of SPSS has been a special *.spo file since version 7.0. As far as I know, there is no word processing software that can read it, but SPSS provides the function of transferring the file to other formats. Select the File menu->export in the OUTPUT window of SPSS to save the result file as an HTML file and a TXT file. Of course, it is much uglier than the spo file. Charts are automatically converted into JPG images and cannot be edited. Therefore, it is better to export after all modifications are completed. In addition, this command can also be performed on a single picture or table. Select the desired picture or table, right-click, and select EXPORT in the shortcut menu.

I want to paste the SPSS result table directly into WORD for use. How can I keep the original format and paste it?

Select the desired table, right-click, and select copy object in the shortcut menu. At this time, the pasted table will maintain its original format (actually what is pasted is a picture).

R language vs. SPSS?

Both spss and R language are good statistical analysis software. The operation interface and result interface are both in Chinese language, so there is no need to worry about usage problems.

Compared with R language, spss is simpler to operate and easier to get started. It does not require a strong programming foundation. As long as you have a simple understanding of Windows operations, you can get started easily. Of course, for those who like programming, you can also choose to use programming statements. It can be said that whether you are a professional or a non-professional, you can easily control spss. But one thing is that it is not open source software, and it takes up slightly more memory than R.

R language is a very professional statistical analysis software with more comprehensive functions. R language is more suitable for professionals to use. It is more complicated than spss and requires a certain programming foundation. To use it, you need to write code statements. Of course, because it is implemented in code, it is more flexible in use.
