Construct a grouped frequency distribution table AND histogram showing the distribution of overall grade averages. Use an interval width of 10 points
Scenario: Two researchers are examining academic success. They use the same set of 10 high
school student participants, but they each measure academic success differently. Researcher 1
measures academic success by asking the participants to self-report which letter grade is most
typical for them to receive on an assignment on the standard A through F scale. Researcher 2
measures academic success by accessing the students' academic records and retrieving their
overall grade average from the school's system. The participants' scores are shown below.
