What are the different types of variables in SPSS?
Variables in the model. c. Model – SPSS allows you to specify multiple models in a single regression command. This tells you the number of the model being reported. d. Variables Entered – SPSS allows you to enter variables into a regression in blocks, and it allows stepwise regression.
Which is an assumption to check when using SPSS Statistics?

How to interpret results of the linear regression test in SPSS?
A value is greater than 1 for F-ratio yield efficient model. In the above table, the value is 67.2, which is good. These results estimate that as the p-value of the ANOVA table is below the tolerable significance level, thus there is a possibility of rejecting the null hypothesis in further analysis.
What should be the default value for SPSS?
Choosing 0.98 -or even higher- usually results in all predictors being added to the regression equation. By default, SPSS uses only cases without missing values on the predictors and the outcome variable (“ listwise deletion”). If missing values are scattered over variables, this may result in little data actually being used for the analysis.
