If you want to know more about statistics, methodology, or research bias, make sure to check out some of our other articles with explanations and examples. NoteTo get a clear idea of your data’s variability, the range is best used in combination with other measures of variability like interquartile range and standard deviation. For students between the ages of 11 and 14. It can’t tell you about the shape of the frequency distribution of values on its own. Learn how to calculate and interpret the mean, median, mode and range to find averages with this BBC Bitesize Maths article. Although we have a large range, most values are actually clustered around a clear middle.īecause only two numbers are used, the range is easily influenced by outliers. For the absolute value function f(x) x, there is no restriction on x. In the example above, the range indicates much more variability in the data than there actually is. Both the domain and range are the set of all real numbers. With an outlier, our range is now 42 years. Using the same calculation, we get a very different result this time: Range example with an outlierOne value in your data set is replaced with an outlier. Tangent, like other trigonometric functions, is typically defined in terms of right triangles and in terms of the unit circle. One extreme value in the data will give you a completely different range. Tangent, written as tan(), is one of the six fundamental trigonometric functions. 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. In statistics, range represents the difference between the highest value of a data set and the lowest value of a data set.Order all values in your data set from low to high.The range() function returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and stops before a specified number. Example 1: Find the Domain and Range of a Graph. The range is the easiest measure of variability to calculate. In mathematics, the range of a function may refer to either of two closely related concepts: the codomain of the function, or.
