An example of this rhetorical appeal is as follows:
"Our new reading program has improved scores on the reading portion of the ACT by, on average, four points. Approximately 95 percent of students benefitted from the program. We predict, based on our figures, that, within five years, our school will be ranked among the top 20 percent in the state on the reading portion of the exam. This program, therefore, has been a massive success."
