Measures of Central Tendency: Arithmetic Mean

The video tutorial explains the significance of numerical figures in daily life and introduces the concept of central tendency, focusing on arithmetic mean, median, and mode. It provides detailed methods for calculating the arithmetic mean, including examples and properties. The tutorial also covers mean calculation for frequency distribution using the direct method and introduces advanced methods like assumed mean and step deviation.
