Identify the research variables (for items 1 & 2) and the central phenomenon used in
the following scenarios.
1. An experiment is performed on plants to see how different liquids affect plant
growth. Each plant in the experiment is given a different liquid; water, apple juice,
or milk. Each plant has the same amount of soil, same amount of sunlight, and the
same amount of liquid.
2. A survey is conducted to see how race relates to academic success. Four race were
identified in the study: Caucasian, African, Asian, Latin. The gender, socioeconomic
status, and the background experience, (relevant to discrimination) were also considered
as influencing factors in the study.
3. A researcher decided to conduct a grounded theory study related to the process
of cultural transmission of several ethnic groups in Region 12. Knowing that this
needs closer inspection, he also decided to stay in the vicinity of these ethnic
groups for at least three months to see first-hand how (if there is still) cultural
transmission happens in this ethnic groups.
