Between-groups design is presented as which of the following in relation to independent design?

• A. True, it is the same as a within-subjects design.
• B. It is a design focusing on repeated measures within the same subjects.
• C. It is a design where groups are tested across time intervals.
• D. It is another name for an independent design.

Answer: (D)

Between-groups design involves assigning each participant to only one condition, so the groups are independent. This aligns with the term independent design, since the comparisons are made between separate groups rather than within the same participants across conditions. The other descriptions describe designs where the same individuals experience multiple conditions (within-subjects or repeated measures) or where participants are followed over time, which are not between-groups designs. In practice, this distinction guides the analysis toward independent-samples tests (like an independent-samples t-test or between-subjects ANOVA) rather than paired or repeated-measures tests.
