• 25

What is the median of the following numbers: 0, 1, 2, 3, 4?

• 1

• 2

• 3

• 4

How do you find the median in an even set of numbers?

• Arrange the numbers in order and find the average of the two middle numbers.

• Select the largest number in the set.

• Choose the smallest number in the set.

• Add all the numbers together and divide by the total count.

What is the difference between mean and median?

• Mean is the average of all numbers, while median is the middle value when numbers are arranged in order.

• Mean is the middle value, while median is the average of all numbers.

In the data set: 3, 5, 7, 9, what is the median?

• 5

• 6

• 7

• 8

What is the formula for calculating the mean?

• Mean = (Sum of all values) / (Number of values)

• Mean = (Sum of all values) * (Number of values)

• Mean = (Maximum value + Minimum value) / 2

• Mean = (Sum of squared values) / (Number of values)

How do you calculate the range of a data set?

• Range = Maximum value + Minimum value.

• Range = Maximum value - Minimum value.

• Range = Average value - Minimum value.

• Range = Maximum value / Minimum value.

What is the mode?

• The mode is the number that appears most frequently in a data set.

• The mode is the average of all numbers in a data set.

• The mode is the middle value when the numbers are arranged in order.

• The mode is the largest number in a data set.

To find the _________ you add up all the numbers and then divide by how many numbers you have.

• Median

• Mode

• Mean

• Range

What does it mean if a data set has no mode?

• It means that no number appears more than once.

• It means that all numbers appear with the same frequency.

• It means that the data set is empty.

• It means that there is a tie between two or more numbers.
