Exploring Mean, Median, Mode, and Range

This Minity Maths video tutorial explains the concepts of mean, median, mode, and range. It begins with an introduction to the channel and a brief explanation of each statistical measure. The mean is described as the total of all numbers divided by the count of numbers. The median is the middle value in an ordered list, with a method for handling two middle values. The mode is the most frequently occurring number, and the range is the difference between the highest and lowest numbers. An example problem is provided to demonstrate these calculations, followed by a practice question for viewers to try.

What is the mean of a set of numbers?

• The middle value of the numbers

• The sum of all numbers divided by the count of numbers

• The number that appears most frequently

• The difference between the highest and lowest numbers

How do you find the median in a set with an even number of elements?

• Average the two middle numbers

• Choose the smallest number

• Subtract the smallest from the largest number

• Pick the most frequent number

What does the mode represent in a dataset?

• The middle value

• The difference between the highest and lowest values

• The most frequently occurring number

• The average of all numbers

How is the range calculated in a set of numbers?

• Find the average of all numbers

• Add the smallest and largest numbers

• Divide the largest number by the smallest

• Subtract the smallest number from the largest

How do you calculate the mean of the numbers 4, 5, 6, 7, 8?

• Subtract the smallest from the largest

• Add all numbers and divide by 5

• Count the frequency of each number

• Pick the middle number

What is the median of the numbers 1, 2, 3, 4, 5?

• 3

• 2

• 5

• 4

If a list of numbers is 2, 3, 3, 3, 4, 5, what is the mode?

• 5

• 4

• 3

• 2

What is the range of the numbers -4, 1, 3, 7?
