To quickly understand the age spread, you subtract the youngest age from the oldest: 5 \u2013 1 = 4. This \u201c4\u201d is the <em>range<\/em>-a simple measure that tells you how spread out the ages are.&nbsp;<\/p>\n\n\n\n<p>In statistics, the range is a fundamental concept used to describe how data values vary, making it essential for anyone analysing numbers, from students to business professionals.<\/p>\n\n\n\n<p><strong>Key Takeaways<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The range in statistics measures the spread between the highest and lowest values.<\/li>\n\n\n\n<li>It is calculated simply by subtracting the minimum value from the maximum value.<\/li>\n\n\n\n<li>The range is quick to compute but sensitive to outliers and extremes.<\/li>\n\n\n\n<li>It gives a basic sense of variability, especially in small datasets.<\/li>\n\n\n\n<li>Range should be used with other measures for a complete analysis of data spread.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"what-is-range\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_Range\"><\/span><strong>What is Range?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The <em>range in <\/em><a href=\"https:\/\/www.pickl.ai\/blog\/skewness-in-statistics\/\"><em>statistics<\/em><\/a> is a measure of variability that shows the difference between the largest and smallest values in a dataset. It provides a quick sense of how spread out the numbers are. The range is especially useful for understanding the extent of variation within small datasets, as it highlights the span from the minimum to the maximum value.<\/p>\n\n\n\n<p>For example, if the scores in a test are 70, 85, 90, and 95, the range is 95 \u2013 70 = 25. This indicates that the scores are spread over 25 points.<\/p>\n\n\n\n<h3 id=\"range-formula-and-calculation\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Range_Formula_and_Calculation\"><\/span><strong>Range Formula and Calculation<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>The formula for calculating the range is straightforward:<\/p>\n\n\n\n<p>Range=Maximum Value\u2212Minimum ValueRange=Maximum Value\u2212Minimum Value<\/p>\n\n\n\n<p><strong>Steps to Calculate the Range:<\/strong><\/p>\n\n\n\n<p><strong>1:<\/strong> Identify the smallest (minimum) value in the dataset.<\/p>\n\n\n\n<p><strong>2:<\/strong> Identify the largest (maximum) value in the dataset.<\/p>\n\n\n\n<p><strong>3:<\/strong> Subtract the minimum value from the maximum value.<\/p>\n\n\n\n<h4 id=\"example\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Example\"><\/span><strong>Example<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p><strong>Dataset: <\/strong>13, 21, 21, 40, 48, 55, 72<\/p>\n\n\n\n<p><strong>Range = <\/strong>72 \u2013 13 = 59.<\/p>\n\n\n\n<h2 id=\"range-for-different-data-types\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Range_for_Different_Data_Types\"><\/span><strong>Range for Different Data Types<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"852\" height=\"333\" src=\"https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6.png\" alt=\"range for different data types\" class=\"wp-image-22210\" srcset=\"https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6.png 852w, https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6-300x117.png 300w, https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6-768x300.png 768w, https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6-110x43.png 110w, https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6-200x78.png 200w, https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6-380x149.png 380w, https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6-255x100.png 255w, https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6-550x215.png 550w, https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6-800x313.png 800w, https:\/\/www.pickl.ai\/blog\/wp-content\/uploads\/2025\/05\/image5-6-150x59.png 150w\" sizes=\"(max-width: 852px) 100vw, 852px\" \/><\/figure>\n\n\n\n<p><strong>Ungrouped Data:<\/strong><\/p>\n\n\n\n<p>Range = Highest value \u2013 Lowest value<\/p>\n\n\n\n<p><strong>Grouped Data:<\/strong><\/p>\n\n\n\n<p>Range = Upper-class boundary of the highest interval \u2013 Lower-class boundary of the lowest interval<\/p>\n\n\n\n<h2 id=\"range-in-dataset\" class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Range_in_Dataset\"><\/span><strong>Range in Dataset<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The range is applicable to any numerical dataset, whether it\u2019s ages, prices, temperatures, or scores.
