Spss — 26 Code

Useful for reverse-scoring survey items or grouping data.

* Recode Var1 into a new variable called Var1_Reversed.
RECODE Var1 (1=5) (2=4) (3=3) (4=2) (5=1) INTO Var1_Reversed.
EXECUTE.

Since your request is very broad ("spss 26 code"), I have written a comprehensive post covering the most common syntax operations you will need in SPSS 26. This is formatted so you can copy and paste it directly.

Independent samples t-test:
T-TEST GROUPS=TreatmentGroup(0 1)
  /MISSING=ANALYSIS
  /VARIABLES=PostTestScore
  /CRITERIA=CI(.95).

Paired t-test:
T-TEST PAIRS=PreTest WITH PostTest (PAIRED)
  /CRITERIA=CI(.95)
  /MISSING=ANALYSIS.

One-way ANOVA with post-hoc:
ONEWAY Outcome BY TreatmentGroup
  /STATISTICS DESCRIPTIVES HOMOGENEITY
  /MISSING ANALYSIS
  /POSTHOC=LSD TUKEY ALPHA(0.05).

Linear regression:
REGRESSION
  /DESCRIPTIVES MEAN STDDEV CORR SIG N
  /MISSING LISTWISE
  /STATISTICS COEFF OUTS CI(95) R ANOVA COLLIN TOL
  /DEPENDENT BloodPressure
  /METHOD=ENTER Age Weight ExerciseHours
  /SAVE PRED RESID.

Logistic regression (binary):
LOGISTIC REGRESSION VARIABLES Purchase
  /METHOD=ENTER Age Income SiteVisits
  /CONTRAST (Gender)=Indicator
  /PRINT=CI(95)
  /CRITERIA=PIN(0.05) POUT(0.10) ITERATE(20) CUT(0.5).

One‑sample t‑test:
T-TEST /TESTVAL=100 /VARIABLES=IQ_Score.

Independent samples t‑test:
T-TEST GROUPS=Treatment(0 1) /VARIABLES=Outcome.

Paired t‑test:
T-TEST PAIRS=PreTest WITH PostTest (PAIRED).

DEFINE !do_all ()
!DO !var !IN (Age Income Satisfaction)
  FREQUENCIES !var.
!DOEND
!ENDDEFINE.
!do_all.

Note: For true Python scripting (more powerful), SPSS 26 also supports SPSS Statistics‑Python Integration via BEGIN PROGRAM…END PROGRAM.
Example with Python:
BEGIN PROGRAM.
import spss
for v in ['Age','Income']:
    spss.Submit("FREQUENCIES %s." % v)
END PROGRAM.
