What does the mean of a dataset represent?

The mean of a dataset represents the average value, calculated by summing all the data points and then dividing by the number of points in the dataset. This measure is significant because it provides a central value that summarizes the entire dataset, allowing for a quick assessment of the overall magnitude of the values being analyzed.

In contrast to other measures of central tendency, such as the mode (which identifies the most frequently occurring value) and the median (which indicates the middle value when the data is ordered), the mean is sensitive to all data points, including outliers, which can heavily influence its value. The mean is particularly useful in situations where data points are symmetrically distributed, making it an excellent representation of central tendency in those cases.

Additionally, the mean can also serve as a starting point for further statistical analysis, such as variance and standard deviation, which assess how spread out the values in the dataset are around that average.
