Final answer:
The mean is the average of a set of values, while the median is the middle value when the data is arranged in ascending order.
Step-by-step explanation:
The mean is the measure of central tendency that represents the average of a set of values. It is calculated by summing up all the values in the set and dividing the total by the number of values.
The median, on the other hand, is the measure of central tendency that represents the middle value when the data is arranged in ascending order. If the data set has an even number of values, the median is the average of the two middle values.
