## Answer Key

**1. D**

First add all the numbers 200,000 + 10,020 + 30,000 + 15,000 + 1080 = 256,100. Then divide by 5 (the number of data provided) = 256,100/5 = 51,220

**2. C**

First add all the numbers 1 + 2 + 3 + 4 + 5 +6 + 7 +8 + 9 + 10 = 55. Then divide by 10 (the number of data provided) = 55/5 = 11

**3. A**

First add all the numbers 2.5 + 9.5 + 4.5 + 1.25 + 7.05 + 20.8 = 45.6. Then divide by 6 (the number of data provided) = 45.6/6 = 7.6

**4. C**

First arrange the numbers in a numerical sequence – 1, 3, 7, 7, 9, 9, 11, 13, 15, 15, 21. Next find the middle number. The median = 9

**5. B**

First arrange the numbers in a numerical sequence – 43, 45, 50, 65, 66, 69, 73, 75, 77, 80, 86, 90, 91. Next find the middle number. The median = 73

**6. A**

First arrange the numbers in a numerical sequence – 3, 32, 64, 67, 109. Next find the middle number. The median = 64

**7. D**

Simply find the most recurring number. All the numbers in the series appeared only once. The answer is No Mode

**8. D**

Simply find the most recurring number. The most occurring number in the series is 177

**9. C**

Simply find the most recurring number. The most occurring numbers in the series is 2 and 6
