Statistics: Mean, Median, Mode, Range

The video tutorial covers the concepts of mean, median, mode, and range. It explains how to calculate the mean by adding numbers and dividing by the count, how to find the median by arranging numbers and identifying the middle value, how to determine the mode by identifying the most frequent number, and how to calculate the range by subtracting the smallest number from the largest. Each concept is illustrated with examples to aid understanding.

• Divide the total by the number of values

• Find the middle number

• Add all the numbers together

• Subtract the smallest number from the largest
