Which statistical measure is employed to summarize the central tendency of a dataset?

The mean is a fundamental statistical measure used to summarize the central tendency of a dataset. It represents the average value, calculated by adding up all the values in the dataset and dividing by the number of observations. The mean provides a single value that encapsulates the overall trend of the data, making it a useful indicator of the dataset's typical or central value.

While the median and the standard deviation are also important statistical measures, they serve different purposes. The median reflects the middle value of a dataset when it is ordered, thus offering insight into the distribution of values and is particularly useful in skewed distributions. The standard deviation measures the extent to which individual values deviate from the mean, providing information about the spread or variability in the dataset. The range indicates the difference between the highest and lowest values in the dataset, giving a sense of the total spread but not representing central tendency. Therefore, the mean is the most appropriate choice for summarizing the central tendency.
