Final answer:
The best statistic to include on a poster to encourage reading would be the one demonstrating the strong correlation between recreational reading and academic success, as it promotes a positive and motivating message.
Step-by-step explanation:
When adding a fact or statistic to a poster aimed at encouraging kids to read more, it's beneficial to choose a fact that directly connects the act of reading with positive outcomes. The best fact to add in this scenario would be: 'Research has found a direct link between the amount of time children read for pleasure and their academic reading achievement.' This statement directly links reading with academic success, which is a positive and motivating outcome.
Adding a statistic that focuses on the challenges or negative aspects of not reading, such as the high percentage of adults who cannot read and write or the number of students reading below grade level, may not be as effective in inspiring children to read. Instead, highlighting the benefits of reading, as shown by positive reading trends and links to academic achievement, encourages children to see reading as a valuable and beneficial activity.
Furthermore, it is important to note that reading can be enjoyable and enriching as well, just like any other leisure activity. Encouraging children to discover new worlds and exciting stories through books can be a powerful motivator.
