T – Test:
You can read the Val of the test statistic directly from SPSS only if the hinge b= 0. If b/= 0, you must calculate the val by hand/calculator using the estimated coefficient and
standard error.
F – Test:
• You can use the value under F in the ANOVA table in SPSS to find the Val of the F-Test.
• You can use the value under “Sig.” in the ANOVA table in SPSS to find the p-value of the F-Test.
Partial F-Test:
• The full model has k variables and the reduced model has g variables, where g < k.
• It is possible to compute the Val and the associated p-value in SPSS for partial F-tests: Analyze → Regression → Linear → Place Y variable in dependent box. →Place all k
variables (the complete model) in the Independent box.→ Press Next → Add the variables you want to remove in the Block 2 of
2box→ChangeMethodtoRemove.→ClickStatistics→ Tick R squared change →Click Continue and OK. The Val can be found under “Model Summary”, the 2nd row in the
column “F Change. The associated p-value is the 2nd row in the column “Sig. F Change”
