1. Mr. Turner has two Math 2 classes. With one class, he lectured and the students took notes.
In the other class, the students worked in small groups to solve math problems. After the first
test, Mr. Turner recorded the student grades to determine if his different styles of teaching
might have impacted student learning.
Class 1: 70, 90, 88, 89, 86, 86, 86, 86, 84, 82, 77, 79, 84, 84, 84, 86, 87, 88, 88, 88
Class 2: 80, 81, 81, 75, 70, 72, 74, 76, 77, 77, 77, 79, 84, 88, 90, 86, 80, 80, 78, 82
Analyze his student grades by finding the mean, median, quartiles, and range,
Class 1: mean ________ median ________ Q1 ________ Q3 ________ range _______
Class 2: mean ________ median ________ Q1 ________ Q3 ________ range _______
