Question

gwyneth, an advocate of sexual reform, knows (from research studies) that condoms can prevent sexually transmitted diseases as well as pregnancy. she decides to educate first-year students at her university about the advantages of using condoms through a short film depicting various characters. some of the characters portray traditional mindsets (refusing to wear condoms); some portray the more liberal mindsets (proponents of condoms); and some are transitional characters whose attitudes move from traditional to more liberal with respect to condom use. gwyneth plans on recording the rates of pregnancy/stds for the first-year students at her university before and after the educational short film. she also plans to compare her results with those of first-year students at a different university with similar demographics who do not watch the educational short film. what is the experimental design that gwyneth chose to use? question 1 options: a) multiple time-series design b) quasi-experiment design c) nonequivalent control group design d) time-series design

Answer 1

Gwyneth is using a nonequivalent control group design to compare outcomes between first-year students exposed to an educational short film on condom use and a similar control group that did not view the film.

Step-by-step explanation:

The experimental design that Gwyneth chose to use is the nonequivalent control group design. This design involves comparing the outcomes of two groups: one that receives the intervention (in this case, the educational short film on the advantages of using condoms) and another that does not receive the intervention, also known as the control group. The two groups are similar, but not identical (hence the term nonequivalent), which means that they are not randomly assigned. Gwyneth's approach allows her to observe changes in rates of pregnancy and sexually transmitted diseases (STDs) in the two different university groups with similar demographics to determine the effectiveness of her educational short film.
