Using attached chart calculate the standard deviation for overall grade average, assuming these 10 people are a population. ( Use the appropriate symbols with all steps of your calculations) Then calculate the standard deviation for overall grade average, assuming these 10 people are a sample
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. Researcher 1: Typical Letter Grade B A C B A D D B B с Researcher 2: Overall Grade Average 85 96 75 86 90 60 59 84 80 70
