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

• 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.

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.
