Measures of Central Tendency and Dispersion
Measures of central tendency and dispersion are fundamental concepts in statistics, providing insights into the characteristics and variability of data sets. Central tendency measures, including mean, median, and mode, offer a succinct summary of the typical or central value within a dataset. Conversely, dispersion measures, such as range, variance, and standard deviation, quantify the spread or variability of data points around the central value. Understanding these measures is crucial in interpreting and analyzing data across various fields, facilitating informed decision-making and robust statistical inference.
