In some occasions, the term "range" can also refer to the mathematical concept of interval.

Obviously, you couldĪlso look at things like the median and the mode. The arithmetic mean, where you actually take Range is one of four simple tools of statistics: 1. In a set of data, the range is the difference between the greatest and smallest value. So this is going to be what? 90 plus 60 is 150. In math, rangeis a statistical measurement of dispersion, or how much a given data set is stretched out from smallest to largest. Order the data from least to greatest and subtract the smallest value from the largest value in the set. Learn how to find range and make a range calculation with examples, exercises and interactive puzzles. The mid-range would be theĪverage of these two numbers. The range of a set of data is the difference between the highest and lowest values in the set. The symbol used to represent the mean is latexbar X /latex, often read as x-bar. The mean is commonly known as the average which is calculated by getting the sum of all values in the list and then divided by the number of entries. To find it, subtract the lowest number in the distribution from the highest. Example 1: Find the mean, median, mode, and range for the following list of values. With the mid-range is you take the average of the The range is the difference between the highest and lowest values in a set of numbers. One way of thinking to some degree of kind ofĬentral tendency, so mid-range. The tighter the range, just to use the word itself, of The larger the differenceīetween the largest and the smallest number. See, if this was 95 minus 65, it would be 30. Want to subtract the smallest of the numbers. ![]() Largest of these numbers, I'll circle it in magenta, Its used in statistics to find out how spread-out different values are. The way you calculate it is that you just Range, which is the difference between the largest and smallest value in the data set, describes how well the central tendency represents the data. The range is the difference between the largest and smallest number in a set of data. So what the range tells us isĮssentially how spread apart these numbers are, and Mid-range of the following sets of numbers. See worked examples, tips and comments from other learners, and the difference between range and domain. In statistics you're given the numbers and you have to figure out what kind of equation they describe. Learn how to find the range of a function, the set of all possible outputs the function can produce, using interval notation and graphing. In ordinary math you're given the relationship of the equation and you just have to plug in the numbers. Do people going to the beach make the temperature go up? Or is it the other way around? In this example it is obvious, but lots of times it isn't. Sometimes there is a relationship, sometimes there is not, and even when there is a relationship it isn't aways easy to figure out what it is. In statistics you're basically given two or more variables (x, y, etc) and you have to figure out if there is a relationship among them. In ordinary mathematics you're given a relationship in the form of an equation (x+y = z) that you can then plug numbers into and get an answer. In this case there obviously is, but in other examples the relationship isn't so obvious. For example, if the temperature goes up on the thermometer, and you count more people going to the beach, then you might want to determine whether there is a relationship between the two things. For students between the ages of 11 and 14. Statistics attempt to establish the relationship between one or more measured things.
