Hello, I have to analyse two research articles about how carbon dioxide affect plant growth. one of the questions I have to answer is to "compare the research approach" for the two articles.

I am not completely certain what " research approach refers to" would i say how their methods were similar?

Clarification would be appreciated.

Of course! When we talk about comparing the research approach in two articles, we are essentially looking at how the studies were designed and conducted. In other words, we are interested in the methods and procedures that the researchers followed to address their research questions.

To compare the research approach of the two articles on how carbon dioxide affects plant growth, you will need to analyze how the studies were similar or different in terms of their experimental design, sampling methods, data collection techniques, and statistical analyses. This will help you understand how the researchers approached their investigations and what techniques they employed to obtain their results.

Here are some specific elements that you can compare to assess the research approach:

1. Experimental Design: Examine whether the studies used similar or different experimental designs, such as controlled laboratory experiments, field studies, or observational studies.

2. Sampling Methods: Evaluate how the researchers selected their study participants, plant samples, or experimental units. Were the samples randomly selected, or were they chosen based on specific criteria?

3. Data Collection Techniques: Analyze the methods employed by the researchers to collect data on plant growth and carbon dioxide levels. Did they use direct measurements, surveys, or other instruments?

4. Statistical Analyses: Assess the statistical tests and analyses performed by the researchers to interpret their data. Were similar statistical methods employed in both studies, or did they differ?

By comparing these aspects of the research approach, you will gain insights into how the two articles approached their investigations and how they may have influenced their findings. Remember to refer back to the original articles to ensure accuracy in your analysis.
