Understanding Mean, Median, and Mode

The video tutorial explains how to find the mean, median, and mode of a set of numbers. It begins by defining each term: the mean is the average, the median is the middle value, and the mode is the most frequently occurring number. The tutorial then demonstrates how to calculate the mean by summing the numbers and dividing by the count. It explains finding the median by ordering the numbers and averaging the two middle values if the count is even. Finally, it identifies the mode as the number appearing most often in the set.

What is another term commonly used for the mean?

• Geometric mean

• Quadratic mean

• Harmonic mean

• Arithmetic mean
