The range is one of the simplest measures of spread in statistics, telling you how spread out your data is. To calculate the range, you subtract the smallest value from the largest value in your data set.
In AQA GCSE Maths, you'll need to find the range from lists of data, frequency tables, and grouped frequency tables. For grouped data, you can only estimate the range by using the class boundaries.
The range is useful for getting a quick picture of data spread, but it has limitations. It only uses two values (the highest and lowest), so it can be heavily affected by outliers. For example, if one student scores 100% on a test while everyone else scores between 40-60%, the range would suggest huge variation when most students actually performed similarly.
In exam questions, you'll often be asked to compare data sets using both an average (mean, median, or mode) and the range. The average tells you the typical value, while the range tells you about consistency. A small range means the data is consistent; a large range means there's more variation.
