**Scenario:** Two researchers are examining academic success using the same set of 10 high school student participants. However, each researcher measures academic success differently. Researcher 1 assesses academic success by asking participants to self-report the letter grade they typically receive on the standard A through F scale. Researcher 2 evaluates academic success by accessing the students' academic records and retrieving their overall grade average from the school's system. The participants' scores are presented in the table below. | Researcher 1: Typical Letter Grade | Researcher 2: Overall Grade Average | |------------------------------------|-------------------------------------| | B | 85 | | A | 96 | | C | 75 | | B | 86 | | A | 90 | | D | 60 | | D | 59 | | B | 84 | | B | 80 | | C | 70 |
