What is the mode, median, range for: 2,2,4,4,7,7,7,11,12,17
Mode = mode frequently occurring score.
Median = 50th percentile, half of scores with higher value, half with lower.
Range = highest score-lowest
Is this correct? Mode 7, median 7, range 15
Right.
To find the mode, median, and range of a set of numbers, follow these steps:
1. Mode: The mode is the number that appears most frequently in the dataset. In this case, the number 7 appears three times, which is more than any other number. Therefore, the mode is 7.
2. Median: The median is the middle number in a sorted list of numbers. To find the median, first, arrange the numbers in ascending order: 2, 2, 4, 4, 7, 7, 7, 11, 12, 17. There are 10 numbers, so the middle two numbers are the 5th and 6th numbers, which are both 7. Since there is no single middle number, the median is the average of these two numbers. Therefore, the median is (7 + 7) / 2 = 7.
3. Range: The range is the difference between the maximum and minimum values in the dataset. In this case, the minimum value is 2, and the maximum value is 17. Therefore, the range is 17 - 2 = 15.
Summary of the results for the dataset:
- Mode: 7
- Median: 7
- Range: 15
