Can the mean be calculated with negative numbers?

Understanding the mean has numerous benefits, from evaluating student performance to managing investments. However, there are also some potential risks to be aware of. For instance, relying solely on the mean can lead to overlooking important details, such as extreme values or outliers. Additionally, calculating the mean can be misleading if the dataset is not representative of the population.

For example, if we have a dataset of exam scores: 80, 90, 70, 85, and 95, the mean would be calculated as:

Why the Mean is Gaining Attention in the US

Mean = (80 + 90 + 70 + 85 + 95) / 5

While this article provides a comprehensive overview of the mean, there's more to explore.
