An outlier is:

• A data point that is clustered with the rest of the data.
• A data point with an extreme value with few other data points around it.
• A data point gathered from an unreliable or untrustworthy source. 
• None of the above.

A skewed data set can be said to be:

• A data set that has most of its data points clustered on one side.
• A perfectly symmetrical data set.
• An unfinished data set.
• None of the above.

Mean and average are synonyms.

• True
• False

A mean (or average) is:

• The sum of all the numbers in a set of data.
• The sum of all numbers in a set of data divided by the number of data points in the set.
• The difference between each number in the data set.
• The product of all the numbers in the data set divided by the number of data points in the set.

The range of a data set is:

• The difference between the greatest and least numbers in a data set.
• The difference between the midpoint and the endpoint of the data set.
• The distance between each data point.
• None of the above.

The median of a data set is:

• The greatest extreme value of a data set when placed in greatest to least order.
• The middle value of a data set when placed in greatest to least order.
• The smallest extreme value in a data set when placed in greatest to least order. 
• None of the above.

The mode of a data set is said to be:

• The number that appears the least often in a data set.
• The number that appears the most frequently in a data set.
• A setting which allows better data visualization.
• Any number that appears only once in the data set.
