1. Central measure is a statistical measure that represents the center or average value of a data set.
2. The most common central measures are mean, median, and mode.
3. The mean is calculated by adding up all the values in a data set and dividing by the number of values.
4. The median is the middle value in a data set when the values are arranged in ascending or descending order.
5. The mode is the value that appears most frequently in a data set.
6. Central measures are used to summarize and describe the central tendency of a data set.
7. Central measures are sensitive to outliers, or extreme values, in a data set.
8. Central measures can be influenced by the distribution of the data set, such as skewness or symmetry.
9. Central measures are used in various fields, including statistics, economics, and social sciences, to analyze and interpret data.

Characteristics of Central Measures
1. Uniqueness: A central measure should provide a unique value that represents the center of the distribution.
2. Stability: The central measure should be relatively unaffected by extreme values in the distribution.
3. Location: The central measure should indicate the location of the data on the number line, either in the center or at a specified point of reference.
4. Representativeness: The central measure should provide a good estimate of the typical value in the distribution.
5. Interpretability: The central measure should be easy to understand and convey meaningful information about the data.
6. Sampling Bias: The central measure should be calculated based on a representative sample to avoid sampling bias.
7. Sensitivity to Outliers: Some central measures are more sensitive to outliers than others. A robust central measure should be less influenced by extreme values.
8. Mathematical Properties: The central measure should have desirable mathematical properties, such as being algebraic operations (e.g., mean and median can be used in equations).
9. Correspondence with Other Measures: The central measure should correspond to other measures of centrality, such as dispersion or skewness, to provide a comprehensive understanding of the distribution.
10. Purpose of Use: The choice of a central measure depends on the purpose of the analysis. For example, the mean is suitable for calculating averages, while the median is better for skewed distributions.
