Final answer:
Credibility in a report can be achieved by citing reliable statistics, using authoritative quotes, presenting evidence fairly, and maintaining an objective and neutral tone.
Step-by-step explanation:
Ways to build credibility for your report include citing supporting statistics and their sources, and using authoritative quotes to emphasize the seriousness of the problem. To ensure credibility, it's essential to present evidence from reliable and respected sources, ensuring not to distort their original context. Additionally, the use of neutral language that shows an objective stance, a logical structure of the report, and fair and accurate citation of sources will further establish trustworthiness and appeal to readers on an ethical level. Providing lengthy explanations is only valuable if they contribute directly to the reader's understanding, but pontificating or presenting opinions as fact would detract from the report's credibility.
