Can the Mean be Negative?
Mean = (Sum of all values) ÷ (Number of values)
What is the Mean of a Zero-Sum Game?
The mean, also known as the average, is a numerical value that represents the central tendency of a dataset. It's calculated by adding up all the values in a dataset and dividing by the number of values. For example, let's say you have a list of exam scores: 80, 90, 70, 85, and 95. To calculate the mean, you add up the scores: 80 + 90 + 70 + 85 + 95 = 420. Then, you divide the sum by the number of scores: 420 ÷ 5 = 84. This means that the mean exam score is 84.

While the mean is the average of a dataset, the median is the middle value when the data is arranged in order, and the mode is the most frequently occurring value. For example, if you have the exam scores 80, 90, 70, 85, and 95, the median would be 80, and the mode would be 80 if it occurred more than once.
The mean can be influenced by outliers or skewed data, making it less representative in certain situations. It's essential to consider other statistical measures, such as the median and mode.
