Range
The set of output values of a function.
Range is a statistical term that refers to the difference between the largest and smallest values in a dataset. It is a measure of dispersion or variability and indicates the spread or diversity in the data. The range is calculated by subtracting the smallest value from the largest value. For example, if we have a dataset of test scores for 10 students, and the highest test score is 95 while the lowest test score is 60, the range would be 35 (95 – 60).
However, it is important to note that the range is affected by outliers, which are extreme values that deviate significantly from the rest of the data. In such cases, the range may not be an accurate representation of the spread of the dataset. Therefore, it is recommended to use other measures of dispersion such as standard deviation or interquartile range that are more robust to outliers. Overall, the range is a simple and quick measure of dispersion that provides a basic understanding of the spread of the data.
