In a game, points were won and lost, represented by integers. 1.įind the range of these distances run by 6 marathon runners:įind the range of these race times given in seconds:ħ.3 s, 8.4 s, 8.0 s, 7.5 s, 9.4 s, 8.7 s, 9.1 sĮmployees at a retail store are paid the hourly wages listed below. After you click ENTER, a message will appear in the RESULTS BOX to indicate whether your answer is correct or incorrect. Then subtract the smallest value from the largest value in the set.ĭirections: Click once in an ANSWER BOX and type in your answer then click ENTER. To find it, first order the data from least to greatest. Summary: The range of a set of data is the difference between the highest and lowest values in the set. Highest - lowest = 8.3 hr - 2.7 hr = 5.6 hr What is the range of times given in hours below? Highest - lowest = 19 -12 = 19 + +12 = +31Įxample 3: A marathon race was completed by 5 participants. Kaiser listed 9 integers on the blackboard. Since 23 is the lowest value and 54 is the highest value, therefore, the range of the observations will be Hence, 31 is the required answer. Solution: Let us first arrange the given values in ascending order. Solution: Ordering the data from least to greatest, we get:Įxample 2: Ms. The range of a set of data is the difference between the highest and lowest values in the set. Example 1: Find the range of given observations: 32, 41, 28, 54, 35, 26, 23, 33, 38, 40. Gasoline prices varied from state to state. Let's take a closer look.Įxample 1: The Jaeger family drove through 6 midwestern states on their summer vacation. She is scheduled to wrap up the last of four performances at the Tokyo Dome on Saturday, Feb. See an example of range calculation and how to use it in a formula. To calculate the interquartile range for a set odd numbers, you need to follow these steps: Step 1: Arrange the numbers in ascending order, Step 2: Identify the median, Step 3: Label each quartile (Q1 and Q3), Step 4: Find the median for each quartile. Learn the meaning of range in statistics, the difference between the lowest and highest values of a data set. This is especially important with large sets of data. Steps to calculate interquartile range for odd number of terms. In the examples below, our first step is to order the data from least to greatest. While finding the range, curly brackets are commonly used to enclose a set of data, so you are aware everything inside the curly brackets belongs together.Definition: The range of a set of data is the difference between the highest and lowest values in the set. 1.67Īrranging the data from least to greatest, we obtain,Ġ.61, 1.64, 1.67, 2.25, 2.96, 2.79, 3.09, 3.73Īnswer: The range of fuel prices is Rs. Learn the definition of range as the difference between the lowest and highest values of a data set, and how to calculate it with examples. Fuel prices varied from state to state he travelled. They may also have been called the input and output of the function. (In grammar school, you probably called the domain the replacement set and the range the solution set. Mr Alex drove through 8 southern states on his summer vacation. Domain and Range The domain of a function f ( x ) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. Here are the range (22) and the midrange (83) of our data: The minimum data value is. Thus, the range of this specific data set is 54 percentage points. The range tells how far the data are spread out combined with the midrange (the value halfway between the endpoints, which is yet another sort of average), we can find the interval containing all the data. Next, subtract the lowest value from the highest value determined: Now, you need to find out the range of this data set or we can say the range of the students' grades?įirst, we need to determine the highest as well as the lowest value of the data set i.e Whether the values you have are negative or positive, even fractions or whole numbers, the process is simply the same. In mathematics, a range is a difference between the lowest and highest values of a numeral. All you need to do is order all the values in the data set in ascending order and then minus or subtract the lowest value from the biggest one.
