The document discusses different measures of central tendency including the mean, median, and mode. The mean is the average value and considers all scores, but can be impacted by outliers. The median is the middle value when scores are arranged in order and is less impacted by outliers. The mode is the most frequently occurring value and can be used for both numerical and categorical data, but may not always indicate the true central tendency. Each measure has advantages and limitations, and different measures are better suited for certain types of data distributions.
