Mean, Median, Mode

What is the first step to find the Median?

• Sort the data from least to greatest.

• Calculate the mean of the data set.

• Identify the mode of the data set.

• Remove the outliers from the data set.

What is the Mean?

• The mean is the middle value in a set of numbers.

• The mean is the average of a set of numbers, calculated by adding all the numbers together and dividing by the count of numbers.

• The mean is the largest number in a set of numbers.

• The mean is the difference between the highest and lowest numbers in a set.

What is the Median?

• The median is the middle value in a list of numbers sorted from least to greatest.

• The median is the average of all numbers in a list.

• The median is the largest number in a list of values.

• The median is the smallest number in a list of values.

If the data set is 5, 5, 6, 7, 8, what is the Mode?

• 5

• 6

• 7

• 8

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.

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

• It means that no number appears more than once in the data set.

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

• It means that the data set is empty.

• It means that there is a single number that appears most frequently.

If a data set has an even number of values, how do you find the Median?

• You find the median by averaging the two middle numbers.

• You find the median by selecting the highest value.

• You find the median by taking the lowest value.

• You find the median by counting the total number of values.

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

• The range is found by adding the smallest number in the set to the largest number.

• The range is found by multiplying the smallest number in the set by the largest number.

• The range is found by subtracting the smallest number in the set from the largest number.

• The range is found by dividing the largest number in the set by the smallest number.

What is the Mean of the data set 1, 0, 1, 5, 6, 3, 4?

• 2.85

• 3.00

• 4.00

• 2.50

If the data set is 1, 2, 3, 4, what is the Median?

• 1

• 2

• 3

• 4
