What do you call the upper and lower limits of a set of numbers?

The term that refers to the upper and lower limits of a set of numbers is known as the range. The range is calculated by taking the highest value in the set and subtracting the lowest value. This provides a measure of how spread out the values in the set are, offering insights into the variability within the data.

In contrast, the median represents the middle number of a data set when the numbers are arranged in ascending order, which is different from identifying the limits. The average, or mean, is obtained by adding all the numbers together and dividing by the count of numbers, providing a central value rather than limits. Standard deviation measures the amount of variation or dispersion among the numbers, indicating how much the values deviate from the mean, but does not define the boundaries of the data set. Thus, range is the precise term for denoting the upper and lower limits of a numerical set.
