Mean, Median, and Mode

What is the mean, median, and mode of the data set: 4, 6, 9, 11, 8, 13, 12?

• Mean: 9, Median: 9, Mode: none.

• Mean: 8, Median: 9, Mode: 9.

• Mean: 10, Median: 11, Mode: 4.

• Mean: 9, Median: 8, Mode: 6.

What is the mean of the following data set: 23, 26, 25, 24, 23, 24, 6, 24, 23?

• $22

• $24

• $23

• $25

If a data set has no repeating numbers, what can you say about its mode?

• The mode is the highest number in the set.

• The mode is the average of the numbers.

• The mode is none, as there are no numbers that appear more than once.

• The mode is the most frequently occurring number.

What happens to the mean if you add a new number to the data set?

• The mean will remain unchanged regardless of the new number.

• The mean will always increase by the value of the new number.

• The mean will change depending on the value of the new number relative to the existing mean.

• The mean will decrease if the new number is less than the existing mean.

How do you find the mean of a data set?

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

• Multiply all the numbers together and divide by the total count of numbers.

• Subtract the smallest number from the largest number.

• Add the largest and smallest numbers together and divide by two.

What is the median?

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

• The median is the middle number in a sorted list of numbers.

• The median is the largest number in a list.

• The median is the smallest number in a list.

What is the median of the following data set: 4, 6, 9, 11, 8, 13, 12?

• 7

• 8

• 9

• 10

How do you find the median of a data set?

• Arrange the numbers in order from least to greatest and identify the middle number.

• Calculate the average of the highest and lowest numbers.

• Sort the numbers in descending order and select the first number.

• Identify the mode of the data set.

How can you tell if a data set is skewed?

• If the mean is greater than the median, the data set is positively skewed.

• If the mean is equal to the median, the data set is normally distributed.

• If the median is greater than the mode, the data set is negatively skewed.

• If the mode is greater than the mean, the data set is positively skewed.

What is the relationship between mean, median, and mode in a normal distribution?

• In a normal distribution, the mean, median, and mode are all equal.

• In a normal distribution, the mean is greater than the median and mode.

• In a normal distribution, the median is less than the mean and mode.

• In a normal distribution, the mode is always the highest value.
