Statistical Measures: Mean, Median, Mode

This video tutorial explains the differences between mean, median, mode, and range. It covers how to calculate each measure: the mean as the average of numbers, the median as the middle value, the mode as the most frequent number, and the range as the difference between the largest and smallest numbers.

What is the mean of the numbers 24, 6, 4, 8, 10, and 12?

• 10

• 6

• 4

• 8

How do you find the median of a set of numbers?

• Find the most frequent number

• Subtract the smallest number from the largest

• Arrange numbers and find the middle one

• Add all numbers and divide by the count

If a dataset has two middle numbers, how is the median calculated?

• By taking the sum of all numbers

• By choosing the smaller of the two middle numbers

• By finding the average of the two middle numbers

• By choosing the larger of the two middle numbers

Which number is the mode in the dataset: 3, 4, 4, 5, 6?

• 5

• 4

• 3

• 6

How is the range of a dataset determined?

• By adding the smallest and largest numbers

• By subtracting the smallest number from the largest

• By identifying the most frequent number

• By finding the average of all numbers
