General Statistical Indices

General statistical indices are numerical tools used to summarize and interpret data. They help us understand overall patterns, trends, and differences within a dataset. Common indices include measures of central tendency like the mean (average), median (middle value), and mode (most frequent value), which describe typical data points. Variability is assessed using indices like range, variance, and standard deviation, indicating how spread out the data are. These indices enable researchers and decision-makers to analyze data efficiently, compare different datasets, and make informed conclusions about the underlying phenomena.
