Answer and Explanation:

The student's research relies on the makabuhay plant as an independent variable and the elimination of the corona virus as a dependent variable.

To conduct these experiments, the student must gather a specific number of people infected with coronavirus and give them a different amount of the medicine made from the makabuhay plant. After that, the student must determine the period of time that this treatment should last and make assessments of possible changes in the degree of infection of the individuals.

The main requirement for this research on "the effectiveness of the makabuhay plant in the treatment of corona virus" is that the researcher should conduct randomized controlled trials.

  • Randomized controlled trials involve the evaluation of the impact of the plant to treat corona virus.

  • To achieve this purpose, the researcher will randomly choose two groups of people infected with the virus.  One group should be the control group, while the other should be the treatment group.

  • The makabuhay plant should be administered to the treatment group while the control group is given a placebo.

  • After some specified period, the researcher will test and re-examine the variables from the two groups to understand the plant's effectiveness.

Thus, to understand the effectiveness (impact) of the makabuhay plant on ending corona virus, the researcher uses the traditional form of research that assesses treatment impact.
