If a paired-samples t-test and an independent samples t-test both have df = 16, which experiment used more participants?
| They both used the same number of participants (n = 18). (A) | |
| (B) |
They both used the same number of participants (n = 17). |
|
(C) |
The paired-samples t-test. |
|
(D) |
The independent samples t-test. |
Homework Answers
option D is correct
The independent samples t-test.
(since for independent sample t test, we need different subject in both groups while for paired test, same subject is used in both groups)

Look at the table for the Paired samples test to find your t
calculated, df, and significance. Remember that significance level
will appear in the Sig (2-tailed) column. Any value that is smaller
than .05 will be significant at the .05 level or higher. In a
sentence describe the results and report them in APA style,
including r2 and evaluation (you will need to calculate
r2 by hand).

Which correctly describes an independent-samples T test? a. it has two sources of variance b. it has one source of variance c. It uses the same group of participants in all of the treatment conditions being compared. d. It uses one group of participants to evaluate a hypothesis about one population mean.
