Calculating the Median of a Set of Numbers

In South Africa, as part of the Grade 9 math curriculum, students learn about statistics, including measures of central tendency like mean, median, mode, and range. To calculate the median of a set of numbers, first arrange the numbers in ascending order. If the quantity of numbers is odd, the median is the middle number. If the quantity is even, the median is the average of the two middle numbers. This concept is crucial for understanding the distribution of data.
