Finding Mean, Mode, Median, and Range

What does the term 'mean' refer to in statistics?

• The average value of a set of numbers

• The most frequently occurring number

• The middle number in a sorted list

• The difference between the highest and lowest numbers

Which of the following is an outlier?

• The most frequently occurring number

• A number close to the mean

• The middle number in a sorted list

• A number far from the majority of other numbers

How do you calculate the mean of a set of numbers?

• Subtract the smallest number from the largest

• Add all numbers and divide by the total count

• Multiply all numbers and divide by the total count

• Identify the number that appears most frequently

How does an outlier affect the mean?

• It has no effect

• It can significantly increase or decrease the mean

• It only affects the mode

• It changes the median

What is the mode of a set of numbers?

• The most frequently occurring number

• The middle number in a sorted list

• The difference between the highest and lowest numbers

• The average of all numbers

Which of the following sets has a mode of 11?

• 2, 4, 6, 8, 10

• 11, 2, 11, 3, 11

• All of the above

• 1, 2, 3, 4, 5

If a set of numbers has an even number of elements, how is the median found?

• By choosing the larger of the two middle numbers

• By taking the average of the two middle numbers

• By choosing the smaller of the two middle numbers

• By adding one to the count and then finding the middle number

What is the median of a set of numbers with an odd number of elements?

• The average of all numbers

• The most frequently occurring number

• The middle number in a sorted list

• The difference between the highest and lowest numbers

What does the range of a set of numbers represent?

• The average value

• The most frequently occurring number

• The difference between the highest and lowest numbers

• The middle value

If the set of numbers is 2, 4, 6, 8, 10, what is the range?

• 8

• 10

• 5

• 6
