Mean
The mean, also known as the average, is a measure of central tendency that is calculated by adding all the values in a dataset and dividing by the number of values. For example, in the dataset {1, 2, 3, 4, 5}, the mean is 3 because (1+2+3+4+5)/5 = 3. The mean is useful for describing the central tendency of a dataset and can be used in a variety of applications, including business. In business, the mean can be used to calculate things like the average sales per customer or the average employee salary. It is important to be aware that the mean can be affected by extreme values or outliers in a dataset, so it may not always be the most appropriate measure of central tendency.

Median

Median
The median is another measure of central tendency, similar to the mean and mode. It is the middle value in a dataset when all the values are arranged in numerical order. If there is an even number of values in the dataset, the median is calculated by taking the mean of the two middle values. The median is useful for describing the central tendency of a dataset because it is not affected by extreme values or outliers, unlike the mean. In business, the median can be used to analyze and interpret data, such as customer expenditure or employee salaries.
