To Explain:
Whether the given research topic is best studied using an experiment or an observation study. How will you design the experiment or observational study.
An observational study is more suitable for this research topic.
Already operational orchid gardens can be observed for the two variables, the orchid productivity and the calcium concentration of the water.
Given:
“Jodi wants to know whether higher level of dissolved calcium in water will promote or inhibit orchid growth.”
Concepts Used:
An experiment necessarily imposes some treatment to the subjects to measure the effect on variables of interest.
In an observational study variables of interest are observed without imposing any treatment on the subjects.
Description:
Since the research topic is resource intensive and it is not feasible to set up orchid gardens with specific levels of calcium in water, an observational study is more suitable for this research topic.
Already operational orchid gardens can be observed for the two variables, the orchid productivity and the calcium concentration of the water.
Conclusion:
An observational study is more suitable for this research topic.
Already operational orchid gardens can be observed for the two variables, the orchid productivity and the calcium concentration of the water.
