1 sample t-test

1. Compare sample mean with

   • Population mean
   • hypothetical value

2. Steps

         • 3 Name of new variable (mean)
           • 4 Name of new variable (mean)
   • 2 Analyze
     • analyze
       • compare mean
         • one sample t-test
           • insert variable you want to test into test variable box
           • test value = comparison value (population mean or hypotetical mean
     • Report step
       • sample Mean ( M = ? ,SD = ?
         • compare higher or lower than test value
           • eg : higher than test value 3.5 t (64 = df ) = 1.21 (mean diff ),p < .001 (sig 2 tail
