PART 1. If SPSS reports a "Sig. (2-tailed)" of
0.0238 for a one sample t-test and you are testing using an alpha

the null hypothesis of your test.
PART 2. When conducting a two independent
samples t-test using SPSS, your "Test Variable(s)" refers to your

PART 3. When conducting a two independent
samples t-test using SPSS, to check how you've coded or grouped
your independent variable (e.g., what numbers you've used to code
gender categories of Female and Male such as 1 = Female and 2 =
Male), you would click under which of the following columns in
"Variable View"?
PART 4. When using SPSS to conduct a paired
samples t-test (AKA related samples t-test), it is only possible to
construct 95% confidence intervals (you cannot construct 90%
confidence intervals).
PART 5. When using SPSS to conduct a one sample
t-test, your "Test Value" in the pop-up box (after selecting a "One
Sample T Test") will come from your sample mean.
