Quizzes About Range, Median And Mode - Quiz

Do you have a math quiz to study for? Do you need help with range, median and mode? Take this quiz to see how many questions you can get correct.

Questions and Answers

1.

The range is defined as
- A.
  
  The difference between the largest and smallest numbers
- B.
  
  The most commonly appearing number
- C.
  
  The middle value when the numbers are placed in ascending or descending order
Correct Answer
A. The difference between the largest and smallest numbers

Explanation
The range is a measure of dispersion in a set of numbers. It is calculated by subtracting the smallest number from the largest number in the set. This calculation gives us the total span or difference between the highest and lowest values in the data. It provides valuable information about the spread or variability of the numbers in the set, allowing us to understand the extent of the data's distribution.

The mode is defined as
- A.
  
  The difference between the biggest and smallest numbers
- B.
  
  The most commonly appearing number
- C.
  
  The middle value when the numbers are placed in order
Correct Answer
B. The most commonly appearing number

Explanation
The mode is the value that appears most frequently in a set of numbers. It is determined by counting the frequency of each number and identifying the one that occurs most often. This is different from the range, which is the difference between the largest and smallest numbers in a set, and the median, which is the middle value when the numbers are arranged in order.

  The difference between the biggest and smallest number
- B.
  
  The most commonly appearing number
- C.
  
  The middle value when the numbers are placed in ascending or descending order
Correct Answer
C. The middle value when the numbers are placed in ascending or descending order

Explanation
The median is the middle value when the numbers are arranged in ascending or descending order. It is not based on the difference between the biggest and smallest number, nor is it the most commonly appearing number. The median is a measure of central tendency that helps identify the middle value in a dataset, dividing it into two equal halves.

Correct Answer
A. 7

Explanation
The given set of numbers is 7, 9, 11, 6, 13, 6, 6, 3, 11. To find the median, we need to arrange the numbers in ascending order. After arranging the numbers, we get 3, 6, 6, 6, 7, 9, 11, 11, 13. The median is the middle number in a set of data when arranged in ascending order. In this case, the middle number is 7, so the median is 7.

Correct Answer
B. 7

Explanation
The median is the middle value of a set of numbers when arranged in order. In this case, the numbers are 3, 6, 6, 6, 7, 9, 11, 11, 13. Since there are 9 numbers, the middle value is the 5th number, which is 7. Therefore, the correct answer is 7.

Correct Answer
D. 10

Explanation
The range is the difference between the highest and lowest values in a set of numbers. In this case, the highest number is 13 and the lowest number is 3. Subtracting the lowest number from the highest number gives us a range of 10.

Correct Answer
A. 13

Explanation
The given list of numbers is: 13, 18, 13, 14, 13, 16, 14, 21. To find the median, we arrange the numbers in ascending order: 13, 13, 13, 14, 14, 16, 18, 21. The median is the middle value, or the average of the two middle values if there is an even number of values. In this case, there are 8 values, so the median is the average of the 4th and 5th values, which are both 14. Therefore, the median is 14.

Correct Answer
B. 8

Explanation
The range of a set of numbers is the difference between the largest and smallest numbers in the set. In this case, the largest number is 21 and the smallest number is 13. Therefore, the range is 21 - 13 = 8.
