Final answer:
To strengthen the claim that increased orchestra enrollment due to publicity, the use of facts and statistics is essential. Consistency in evidence and using statistics as supporting evidence can enhance credibility and effectively support the argument.
Step-by-step explanation:
To strengthen the statement that a 15 percent increase in orchestra enrollment is proof that publicity pays off, the most needed elements are facts and statistics. While anecdotal evidence and academic language can enhance the persuasiveness and readability of the argument, detailed and relevant statistics provide the concrete evidence that can validate the claim. For instance, correlating the increase in enrollment directly to specific publicity efforts, such as mentioning a campaign or publicity action taken prior to the increase, would be more convincing. Additionally, demonstrating a pattern over time or comparing these results with similar cases can further solidify the argument.
In academic writing, it is crucial to be consistent with evidence. If one claims that student seating proximity affects basketball players' performance, relevant evidence would pertain to fan support and player morale rather than finances related to game attendance. Similarly, when discussing the impact of grants on college graduation rates, one should consistently provide data and research that directly link financial aid to student graduation outcomes.
Using statistics as supporting evidence, like how President Johnson used them to advocate for educational reforms in the Great Society, lends credibility to arguments. Statistical evidence creates a basis for rational appeal, demonstrating a need for change or highlighting important trends that validate the argument made.
