Fair Share: Mean of a Data Set

The video tutorial introduces the concept of mean, a statistical measure representing the average of a data set. It explains the process of calculating the mean through two steps: summing the numbers and dividing by the count of numbers. The tutorial also introduces the idea of 'fair share' as a way to understand mean, using examples like sharing cookies, treats, and strawberries equally among people or animals. The video concludes by reinforcing the connection between fair share and mean, encouraging viewers to use this approach for understanding averages.
