The most commonly used measures of central tendency are mean, median and mode. Arithmetic mean or average is calculated by taking the sum of the values divided by the total number of values in the dataset. Median is the middle value of the dataset after arranging it in ascending (or descending) order of magnitude, while mode is defined as the most repeated value in the dataset
