Introduction
In mathematics, the range of a set of numbers is the difference between the highest and lowest values in the set. It is an essential concept in statistics and data analysis, as it provides a measure of the spread or dispersion of the data. In this article, we will explore the concept of range and how to calculate it using a given set of scores.
What is Range?
The range is a measure of the spread or dispersion of a set of numbers. It is calculated by subtracting the lowest value from the highest value in the set. The range is an important concept in statistics, as it provides a measure of the variability of the data.
Calculating the Range
To calculate the range, we need to identify the highest and lowest values in the set of scores. In the given table, the scores are:
- 98
- 76
- 100
- 88
- 82
- 70
The highest score is 100, and the lowest score is 70. To calculate the range, we subtract the lowest score from the highest score:
Range = Highest score - Lowest score = 100 - 70 = 30
Example
Let's consider an example to illustrate the concept of range. Suppose we have a set of exam scores for a class of students:
- 85
- 90
- 78
- 92
- 88
- 76
To calculate the range, we need to identify the highest and lowest scores. The highest score is 92, and the lowest score is 76. To calculate the range, we subtract the lowest score from the highest score:
Range = Highest score - Lowest score = 92 - 76 = 16
Importance of Range
The range is an important concept in statistics, as it provides a measure of the variability of the data. It is used in various applications, such as:
- Data analysis: The range is used to describe the spread of the data and to identify outliers.
- Statistical inference: The range is used to make inferences about the population based on a sample of data.
- Quality control: The range is used to monitor the quality of a process and to detect any deviations from the expected behavior.
Conclusion
In conclusion, the range is an essential concept in mathematics that provides a measure of the spread or dispersion of a set of numbers. It is calculated by subtracting the lowest value from the highest value in the set. The range is an important concept in statistics, as it provides a measure of the variability of the data. It is used in various applications, such as data analysis, statistical inference, and quality control.
Range Formula
The range formula is:
Range = Highest score - Lowest score
Range Example
Suppose we have a set of exam scores for a class of students:
- 85
- 90
- 78
- 92
- 88
- 76
To calculate the range, we need to identify the highest and lowest scores. The highest score is 92, and the lowest score is 76. To calculate the range, we subtract the lowest score from the highest score:
Range = Highest score - Lowest score = 92 - 76 = 16
