Which method is NOT used to find the median?

The median is defined as the middle value in a data set when the values are arranged in order. To find the median, the first step typically involves arranging the numbers in ascending order. After the numbers are ordered, if there is an odd number of data points, the median is simply the middle number. If there is an even number of data points, the median is calculated by averaging the two middle numbers.

In this context, the option that states "Averaging the highest and lowest numbers" does not relate to the calculation of the median. This method would yield a value that is more representative of the range of data rather than identifying the central point of the data set. The process of calculating the median is focused on the middle values rather than extremes, which is why this option does not belong among the methods used to find the median.
