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. Median The central value in a data set when the numbers are arranged least to greatest. Mean The arithmetic average of the numbers in a data set. The range is the measure of dispersion in a data set. Summary: The range of a set of data is the difference between the highest and lowest values in the set. Mean, median, and mode help you approximate the center or central number (s) of a data 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. Solution: Ordering the data from least to greatest, we get:Įxample 2: Ms. 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. This is especially important with large sets of data. In the examples below, our first step is to order the data from least to greatest. Therefore, the age range of participants is 39.Definition: The range of a set of data is the difference between the highest and lowest values in the set. Let us arrange it in order from the lowest to the highest. What is the age range of the participants? Solution: From the data given in the table, let's arrange it in order from lowest to highest.Įxample 3: Galaxy art gallery conducted a painting competition, where around 10 people participated. By using the range formula, find the range difference among these stock prices that will help Mona in investing. Therefore, the range of her test scores is 30.Įxample 2: Mona is looking at investing in some stocks, listed below is a list of four companies along with their stock price. Using the range formula, let us put the values, Calculate the range of her test scores by using the range formula.įirst, let us arrange the given set in order from the lowest to the highest value. The range formula can also be used if the numbers in the data set are either positive or negative.īook a Free Trial Class Examples Using Range FormulaĮxample 1: Emma took 5 tests in chemistry in one semester. Range is a concept that is used in many areas of mathematics, including algebra, calculus, and statistics. These steps can be followed for any type of number such as whole numbers or fractions. Step 2: By using the range formula, subtract the lowest value from the highest value picked from the data set.Step 1: Place all the numbers from the lowest to the highest value in the data set.In order to calculate the range using the range formula, there are two mean steps to be followed: R = Highest Value (H) - Lowest Value (L) Range Formula R = H - L Hence, the formula to calculate the range is: Range, variance, and standard deviation all measure the spread or variability of a data set in different ways. In distribution, the large range means higher variability whereas the small range means low variability. The range formula includes the other aspects of statistics such as mean, median, and mode. The formula helps in determining the center of the set by finding the difference between the lowest and the highest number. ![]() The midrange is the average of the largest and smallest data points. The range formula is mostly used in statistics to determine the range given in a particular data set. The range is the difference between the largest and smallest data points in a set of numerical data. Let's learn more about the range formula and solve a few examples. The range formula is mostly used in statistics where the range is the spread of the numbers or data from the lowest to the highest value and it is commonly used in variability. Example problem finding mean, median, mode and range: Find the mean, median, mode and range of the following data set: 9,4,17,4,7,8,14 Finding the. Then the rest of the scores dont matter for range. The range formula determines the difference between the highest and the lowest values in a given set of numbers. Lets say your best score all year was a 100 and your worst was a 75.
