When including a graphic or statistic in a presentation, the essential piece of information that must be included is its publisher and date of publication. This provides the context necessary to judge the reliability and relevance of the data presented. For Khaled's presentation on climate change, it is crucial to include the source of the statistics (i.e., who published the chart and when it was published) to lend credibility to his information and allow the audience to evaluate the validity and timeliness of the data.
Here's the step-by-step reasoning for determining the essential piece of information:
1. Reliability: Including the publisher allows the audience to recognize whether the source is credible and authoritative.
2. Relevance: The date of publication is important to ensure that the data is up-to-date and relevant to current conditions. Given that climate data can change over time, knowing when the data was published gives context to its applicability.
3. Transparency: Providing these details demonstrates transparency and allows others to verify the information independently if they wish.
4. Professional Standards: Adhering to academic and professional standards typically requires citing the source and date to uphold ethical standards in presenting data.
Therefore, the critical piece of information that must be included with the graphic is its publisher and date of publication.
