Explanation:

• Statistics are used to analyze and present data, showing scale through measures like mean, median, etc. It's not mainly for giving opinions, explaining causes (more for research methods), or presenting history.
• Formal writing uses clear facts rather than long - words (which may not always be appropriate), personal views (more informal), or a casual tone.
• Complex claims are best supported by expert views as they carry more authority compared to simple data, common knowledge, or basic facts which may not be sufficient for complex matters.
