In statistics, range represents the difference betwixt the highest value of a data gear up and the lowest value of a data fix. The range shows how spread out the values in a series are. If the range is a loftier number, then the values in the series are spread far apart; if the range is a small number, then the values in the series are shut to each other. If y'all want to know how to calculate range, just follow these steps.

Steps

1. 1

   List the elements of your data set. To find the range of a set, you'll need to list all of the elements of the set up so that you can identify the highest and everyman numbers. Write downwardly all of the elements. The numbers in this gear up are: xx, 24, 25,19, 24, 28 and 14.^[ane]

   • Information technology tin be easier to identify the highest and lowest number in the set if you list the numbers in ascending social club. In this instance, the set would be rearranged like this: 14, 19, twenty, 24, 24, 25, 28.
   • List the elements of the prepare in social club can also help you make other calculations, such every bit finding the fashion, mean, or median of the set.

2. two

   Identify the highest and lowest numbers in the set. In this instance, the lowest number in the ready is xiv and the highest number is 28.^[2]

3. 3

   Subtract the smallest number in your data prepare from the largest number. Now that you've identified the smallest and largest numbers in the set, all you have to do is subtract them from each other. Subtract 14 from 28 (28 - 14) to get 14, the range of the ready.^[3]

4. 4

   Label the range conspicuously. One time y'all've constitute the range, label it clearly. This will help you avoid confusing it with any other statistical calculations that yous may demand to make for the gear up, such as finding the median, mode, or mean.^[iv]

  First order the data from least to greatest, then subtract the smallest value from the largest value in the set.

• Question

  How practice I calculate mean, median and fashion?

  

  For mean, add all numbers upwardly and divide them by how many numbers there are. For median, place all numbers in ascending lodge and so find the eye number. For mode, notice the most commonly-occurring number.

• Question

  What is the range of 12,400?

  

  You lot take to accept multiple numbers to calculate the range.

• Question

  How can I find the range with negative and positive numbers?

  

  You lot know that if a negative number is higher, it is less (eg -iv < -2), and so the negative with the "highest" number would be the lowest part, and you would and so take the highest positive number, and then subtract the lower part from the higher. Eg: Your numbers are -9, -4, 0, iii, and seven. Well, you take the negative with the "highest" positive number, ie., -nine, and then the highest positive number, 7. Subtract vii - (-9), and y'all get sixteen.

• Question

  Why practise we measure the range?

  

  It gives u.s.a. an overview of a set of data, an thought of how much "space" is independent within those data points.

• Question

  How do I summate domain?

  

• Question

  The range is a data set is 14. If the smallest number in the set is 24, what is the largest number?

  

  Add together the range to the smallest number.

• Question

  How do I calculate mean?

  

  Add together all the numbers and carve up the sum by the number of entries in the range.

• Question

  How practice I create range from mean?

  

  If all you lot know is the mean, yous don't accept plenty information to observe the range.

• The median value of any statistical data set represents the "middle" of the data prepare in terms of the data distribution, not its range. So although y'all might exist tempted to assume that the median of a given data prepare is the range divided past 2--or halfway between the extremes of the range--that usually isn't the case. To observe the correct median, you must list the data elements in order, then locate the element in the center of the listing. That chemical element is the median. For instance, if you have a list of 29 elements, the 15th element will be equidistant from both the top and lesser of the ordered list, so the 15th chemical element is the median, no thing how its value relates to the range.

• You lot tin also interpret "range" in algebraic terms, but first y'all have to grasp the concept of an algebraic function, or a set of operations on whatever given number. Since the function's operations can be performed on any number, even an unknown number, that number is represented by a letter variable, unremarkably "x." The domain is the set of all possible input values you can substitute for that unknown number. The range of a part, then, is the set of all possible results you lot can get after inputting i of the domain values, and performing all the operations divers past the function. Unfortunately, there'southward no single way to summate a function's range. Sometimes graphing the function or calculating several values will demonstrate a clear design. You tin also use your knowledge of the function'due south domain to eliminate possible output values, or narrow down the data set that indicates the range.

"Range" is a term used in statistics to describe the difference betwixt the highest and lowest values in a data set up. To summate range, listing all of the numbers in your data set in society. Then, place the highest and everyman numbers in the set. For instance, if your data set consists of the numbers 23, 40, 57, and 95, then your lowest number would be 23, and the highest would exist 95. Next, subtract the smallest number from the largest one to find the departure. In this case, 95-23 would give you a range of 72. Once you lot calculate the range, make certain to label it to avoid defoliation. For instance, write R (or Range) = 72. To learn how arranging your set in order can help you discover other calculations, read on!
