Fix: Verify that every single command block concludes with a period ( . ).
Commands can be run in "chunks" or loops, making it much faster than navigating menus hundreds of times for similar variables. Advanced Functionality: Certain complex statistical procedures—such as specific
* Independent Samples T-Test: Compare test scores between genders. T-TEST GROUPS=gender(1 2) /VARIABLES=test_score /CRITERIA=CI(.95). * Paired Samples T-Test: Compare pre-test and post-test scores for the same group. T-TEST PAIRS=pre_test_score WITH post_test_score (PAIRED) /CRITERIA=CI(.95). Use code with caution. Chi-Square Test of Independence Examine relationships between two categorical variables.
