1. STATISTICS – MEASURES OF CENTRAL TENDENCY LESSON 2

2. ARITHMETIC MEAN NINE STUDENTS GOT THE FOLLOWING SCORES IN A SURPRISE QUIZ: 83, 68, 62, 80, 70, 95, 83, 75, AND 56. FIND THE MEAN

3. WEIGHTED MEAN AMPY WANTS TO DETERMINE THE AVERAGE GRADE OF HANNAH IN FILIPINO, ENGLISH, MATHEMATICS AND PHYSICS WHICH RECEIVED THE CORRESPONDING GRADE OF 87, 90, 89, AND 92 WITH WEIGHTS OF 1.2, 1.2, 1.5, AND 1.8 RESPECTIVELY. WHAT IS HANNAH’S AVERAGE GRADE?

4. MID RANGE HIGHEST SCORE – LOWEST SCORE 2

5. RANGE HIGHEST SCORE – LOWEST SCORE

6. MEDIAN THERE ARE NINE STUDENTS IN A CLASSROOM WITH AGES 18, 19, 21, 21, 18, 20, 17, 22 AND 23. DETERMINE THE MEDIAN.

7. MEDIAN 17, 18, 18, 19, 20, 21, 21, 22, 23

8. 17, 18, 18, 19, 20, 21, 21, 22, 23 THE SCORE IN THE MIDDLE IS THE MEDIAN

9. MODE TEN MEN ARE ASKED TO ESTIMATE THE NUMBER OF CIGARETTE STICKS THEY SMOKE EVERYDAY AND THE RESULTS ARE 12, 10, 10, 10, 10, 15, 15, 15, 8 AND 4. DETERMINE THE MODE

10. MODE MODE FOR UNGROUPED DATA IS DETERMINED BY THE SCORE THAT OCCURRED THE MOST FREQUENTLY.

11. MODE TEN MEN ARE ASKED TO ESTIMATE THE NUMBER OF CIGARETTE STICKS THEY SMOKE EVERYDAY AND THE RESULTS ARE 12, 10, 10, 10, 10 , 15, 15, 15, 8 AND 4. DETERMINE THE MODE
