Statistically speaking, most people skip to the answers without doing the math first. Don't be a statistic! Work the problems out first! Range is used in real life to make mathematical calculations.
Range can be used to calculate the amount of time that has passed, like when calculating your age. The current year is , and you were born in How old are you? Or how much time has passed? Range is also used in real life to figure out the dispersion of a high school class' test scores, to determine the price range for a service, and much more.

Range is one of four simple tools of statistics : Mean — The arithmetic mean of a set of numbers is its average the sum of the numbers divided by the quantity of numbers Median — The statistical median is the middle number in an ordered set of numbers Mode — The mode is the most commonly occurring number in a data set Range — The range of a data set is the mathematical difference between the largest and smallest value The first three statistical tools are measures of central tendency, or how similar the numbers are.
Range Formula. Notice that when the numbers in the domain are positive, the numbers in the range are positive. Moreover, when the numbers in the domain are negative, the numbers in the range are negative as well. Notice that we can choose any number in the domain except 0. Suppose the numbers in the domain are positive. Similar logic can be used when the numbers in the domain are negative.

K tests, GED math test, basic math tests, geometry tests, algebra tests. Tough Algebra Word Problems. We recommend that you do this, too. This is especially important with large sets of data. Let's take a closer look. Example 1 : The Jaeger family drove through 6 midwestern states on their summer vacation. Gasoline prices varied from state to state. What is the range of gasoline prices? Example 2 : Ms. Kaiser listed 9 integers on the blackboard. What is the range of these integers? Example 3 : A marathon race was completed by 5 participants.
