Statistics is a branch of mathematics that deals with collecting, organizing, analyzing, and interpreting numerical data. The document discusses measures of central tendency, which are values used to describe the center of a data set, including the mean, median, and mode. It provides examples of calculating the mean, median, and mode of various data sets.
