What is an incorrect belief about analytical reports based on this material?

Analytical reports are designed to present data and findings in an objective manner, focusing on analysis rather than personal opinions. The purpose of an analytical report is to inform decision-making by providing evidence, supporting data, and logical conclusions based on the analysis conducted. Therefore, the notion that these reports focus solely on the writer's personal opinions is fundamentally incorrect, as such opinions should not overshadow the factual and analytical nature of the report.

In contrast, the other options correctly reflect the characteristics of analytical reports: they require objective analysis to ensure validity and reliability, they are often intended for internal organizational use to aid in strategic decisions, and they involve comprehensive data collection to support accurate analysis and findings. These aspects highlight the necessity for thorough and unbiased reporting in the context of analytical work.
