Example Questions
Example Question #1 : Mode
Henry has taken a lot of tests this semester in his biology class. In total, he has taken 
The mode is the number that appears most often in a set of numbers.
If we order our number set we get the following:
In this case, because Henry scored 88 three times, that is the mode.
Example Question #2 : Mode
Find the mode of the following numbers:
The mode is the number that occurs the most in a group.
Rearranging our numbers we get:
While 
Example Question #44 : Basic Statistics
What is the mode of the following number set:
The correct answer is 6.
If we reorganize our set in ascending order we get the following:
The mode is the number in a set that appears the most often.
In this particular number set, 6 appears four times and no other number appears more than three times.
Example Question #2 : Mode
Steven is a high school athlete who competes in the long jump. He recorded his last 7 jumps: 15 feet, 18 feet, 19 feet, 12 feet, 15 feet, 18 feet, 15 feet. What is the mode of his long jump lengths?
The mode of a data set is the number that occurs most often. Because Steven managed to long jump 15 feet 3 times, 15 feet is the mode.
Example Question #3 : Mode
For a school project, Jonas asked his classmates how many siblings they had. 
In a data set, the mode is the number that occurs most frequently.
Because 18 of his classmates only had 1 sibling, 1 is the number that appears most often.
Example Question #3 : Mode
The weekly salaries for 6 Starbucks employees are as follows:
What is the mode?
The mode in a set of numbers is the one that appears most frequently.
Because $140 appears 3 times, more than any other number, it must be the mode.
Example Question #4 : Mode
Anthony takes six math tests and achieves these scores:
Find the mode of these scores.
The mode is the number that is repeated most often. In this set of scores, the two numbers repeated are 76 (repeated twice) and 86 (repeated three times). Since 86 is repeated most, it is the mode.
Example Question #54 : Basic Statistics
Stacey achieved these times in a relay race:
Her times are in seconds. What is the mode of these times?
The mode is the number that appears the most within a set of numbers. Since no number is repeated in this set, there is no mode.
Example Question #8 : Mode
Thomas takes five tests and achieves these scores:
Which of the following scores, if Thomas gets that score on his sixth test, will make the mode of this set of numbers above an 
The mode is the number in a set that appears the most. Since there are two numbers within the set of five test scores that appear twice, choose the number that is above 
Example Question #9 : Mode
Which of the following data sets has exactly one mode regardless of the value of 
To see that no other choice works, let's examine them.
