Which method should be used to meet this goal?

An objective review is a systematic evaluation of available data and literature without bias. While it can provide a comprehensive overview of existing knowledge, it may lack the nuanced understanding that experts possess. This method often requires a substantial amount of data, which might not always be available for certain goals, making it less suitable compared to expert opinion.

Historical data refers to information collected from past events or trends. Although it can offer insights into patterns over time, relying solely on historical data may not address current circumstances or emerging challenges effectively. Changes in context or new variables may render past data less relevant, thus making it an inadequate method for meeting the specified goal.

Statistical comparison involves analyzing quantitative data to identify trends or differences among groups. While it can provide valuable insights based on numerical evidence, it may not capture the qualitative aspects or contextual factors that an expert opinion would consider. This limitation can hinder the effectiveness of this approach in achieving specific goals.
