Measures of Central Tendency

What is a common measure of the middle mentioned in the text?

• The total

• The mean

• The range

• The difference

What does the mean of a data set represent?

• The most frequent value

• The middle value when data is ordered

• The sum of all numbers divided by the number of data points

• The largest value in the data set

What is the median?

• The total sum of all data points

• The average of all data points

• The middle number in an ordered set of data

• The most common value in a data set

What does the mode represent?

• The least common value

• The highest value

• The average value

• The most common value

What can cause the mean to be misleading?

• Outliers in the data set

• A small sample size

• A large number of data points

• A symmetrical distribution of data

What is a bimodal distribution?

• Data without a mode

• Data with two modes

• Data with one mode

• Data with more than two modes

How can the relationship between mean, median, and mode indicate data distribution?

• All three always indicate a uniform distribution

• If the median is the highest, the data lacks outliers

• If all three are the same, the data is normally distributed

• If the mean is higher than the median and mode, the data is skewed left

What does a skewed distribution indicate?

• The data is evenly distributed

• There are unusually extreme values on one side of the distribution

• There are no outliers in the data

• The mean, median, and mode are identical
