The video tutorial introduces basic statistical terms such as mode, range, and median. It then provides a detailed explanation of how to calculate the mean of a set of numbers. The process involves summing the numbers and dividing by the count of numbers to find the average.

What is the mode in a set of data?

• The most frequently occurring number

• The average of all numbers

• The middle value when data is ordered

• The difference between the highest and lowest values
