The range in math is the difference between the highest value datapoint and the lowest value datapoint of the given data. Through an interactive and engaging learning-teaching-learning approach, the teachers explore all angles of a topic.īe it worksheets, online classes, doubt sessions, or any other form of relation, it’s the logical thinking and smart learning approach that we, at Cuemath, believe in.įAQs on Range in Statistics 1. About CuemathĪt Cuemath, our team of math experts is dedicated to making learning fun for our favorite readers, the students! Done in a way that not only it is relatable and easy to grasp, but also will stay with them forever. The math journey around range in statistics starts with what a student already knows, and goes on to creatively crafting a fresh concept in the young minds. The mini-lesson targeted the fascinating concept of range in statistics. Range = Highest Score - Lowest Score = 75 - 42 = 33 \(\therefore\) The range of the remaining data is 33 Here we have the Highest Score = 75 and the Lowest Score = 42 Here the numbers 3, 4, and 97 are the outliers.Īfter removing the outliers the remaining data is as follows. Price range = Highest price - Lowest price = 79 - 36 = 43 \(\therefore\) The price range is 43 Given the highest price = 79 and the lowest price = 36 Peter finds the highest price of a varient of potato is 79 cents and the lowest price for another range of potato is 36 cents. Find the price range of the potatoes. Range = Highest Value - Lowest Value = 120 - 3 = 117 \(\therefore \) Range = 117 Here the Lowest Value = 3 and the Highest Value = 120 Let us first list the first 40 multiples of the number 3 Each value of our domain will give us a unique peanut butter and jelly sandwich and therefore we know that the equation we have defined is indeed a function.Joseph wishes to find the range of the first 40 multiples of 3. Specifically, our function will only give us peanut butter and jelly sandwiches, and therefore those are our range. We are planning on making a sandwich, so our codomain can be defined as a set of all of the sandwiches. Our candidate function is given as PB + J + B = PB&J and our domain is all the possible peanut butter, jams, and breads that can be used to make our sandwich. Suppose we want to make a peanut butter and jelly sandwich.
Let's give one last (admittedly rather contrived) example.
So long as the range is a subset (fits completely) inside the codomain, the codomain is valid for the function. For example, in Ohm's law, we could define the codomain as the set of all real and complex numbers, C, which is a larger set than the range of the function that we have defined. Like the domain, the codomain is part of the function definition and it represents the set of values that are considered potential candidates for the output of a function. Unlike the domain, which is part of the definition of the function, the range is a result of a given function and its domain, thus it is not required as part of a function definition.įinally, the term codomain is sometimes used in engineering literature.
