Quizzes About Range, Median And Mode

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.

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 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.

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.

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 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.

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.

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.
