Range
The set of output values of a function.
Range is a statistical measure that represents the difference between the highest and lowest values in a data set. It is used to describe the variability or spread of the data. To calculate the range of a data set, subtract the lowest value from the highest value.
For example, let’s say we have a data set of test scores: 80, 85, 90, 75, 92. To find the range, we subtract the lowest value (75) from the highest value (92):
Range = 92 – 75 = 17
Therefore, the range of this data set is 17. This means that the test scores vary by 17 points from the lowest to the highest score. Range can be helpful in identifying outliers or extreme values in a data set and assessing the overall variability of the data. However, it only takes into account the two extreme values and does not provide information about the distribution of the data between those values.
