One extreme value in the data will give you a completely different range. When paired with measures of central tendency, the range can tell you about the span of the distribution.īut the range can be misleading when you have outliers in your data set. The range generally gives you a good indicator of variability when you have a distribution without extreme values. Then subtract the lowest from the highest value. Participantįirst, order the values from low to high to identify the lowest value ( L) and the highest value ( H). Range exampleYour data set is the ages of 8 participants. This process is the same regardless of whether your values are positive or negative, or whole numbers or fractions. Subtract the lowest value from the highest value.Order all values in your data set from low to high.The range is the easiest measure of variability to calculate. Further to avoid outliers a new quantity called interquartile range is used.You can calculate the range by hand or with the help of our range calculator below. Outliers are generally included in the range. ![]() Range helps to know the minimum and maximum capacity. The range is practically used to know the capacity. 6. What is the practical utility of range? Knowing the range helps to define the scale to represent the data. Range helps to define the spread of the data. Find the difference between the lowest and the highest data point, to get the range.Identify the lowest highest value of the data.Arrange the given data in ascending order or descending order.The process of finding range is statistics can be simplified in three quick steps. Also for a given end datapoint of the data, we can find the other end data point, with the help of range. The range in statistics tells us the size of the data. What does the range in statistics tell us? It also helps us to identify if the given data point is within the defined range or not. Range helps us to know the spread of the data. 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 Joseph wishes to find the range of the first 40 multiples of 3.
