Final answer:
Measures of central tendency tell us about the central or middle part of a series of numbers, including the mean, median, and mode, but they do not provide information about variability, outliers, or skewness.
Step-by-step explanation:
Measures of central tendency primarily tell us about the middle of the series of numbers. These measures include the mean, which is the arithmetic average, the median, which is the middle value when the data is ordered, and the mode, which is the most frequently occurring value. While the mean is sensitive to outliers and can reflect skewness in the distribution, the median is less affected by extreme values and may be a better representation of the central tendency in a skewed distribution. The mode is useful when data has a high frequency of a particular value. However, measures of central tendency do not give us information about the variability, the presence of outliers, or the skewness of a series of numbers.
