Which of the following data sets has exactly one mode regardless of the value of ?
is the correct set; no matter what
is, no value other than 10 can appear four or more times.
To see that no other choice works, let's examine them.
: If
is any number other than 10 or 11, then the number has 10 and 11, and possibly one other number, as modes, each appearing twice.
: If
is not any of the numbers already in the set, the set has no repeated values and thus no mode.
: If
, then the set is bimodal, with 8 and
the modes.
: If
, the set is bimodal, with 10 and 11 the modes.
Compare your answer with the correct one above
Determine the mode of the set.
Mode refers to the number occuring most often, so in this example we are looking for the numbers that repeat and how many times they repeat.
repeats twice
repeats twice
repeats twice
Now because all three numbers repeated an equal amount of time, all three then become our mode.
Answer :
Compare your answer with the correct one above
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 does occur twice,
occurs three times, and no other number does, so
must be the mode.

Henry has taken a lot of tests this semester in his biology class. In total, he has taken tests. His scores on the tests were
,

,
,
,
,

,
,
. What is the mode of all his test scores?
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.

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.

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.

For a school project, Jonas asked his classmates how many siblings they had. of his classmates had
siblings,
had
sibling,
had
siblings, and
had
siblings. What is the mode of the number of siblings his classmates 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.

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.

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.

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.

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 , which is 82. The mode is
.

What is the mode?
Mode is the data point that occurs most frequently. If we arrange in increasing order, we have

Mode is the data point that occurs most frequently.
Let's arrange in increasing order. We have

and
occur twice and are the most frequent. We can have more than one mode so the answer is

What is the mode?
Mode is the data point that occurs most frequently.
Let's arrange in increasing order. We have

John's past five test scores were
.
What is the mode of his test scores?
The mode of a set of numbers is the number that occurs the most times.
Since 85 appears twice, and all other numbers appeared only once, 85 is the mode.
Compare your answer with the correct one above
Using this set of data, find the mode(s).
To find the mode, we must find which number appears the most amount of times. (rememeber: mode = most!)
In this data set:
,
the numbers and
all only appear once. But the numbers
and
appear more than once; these are our candidates for the mode.
Let's go one number at a time. The number four appears four times; the number two appears two times; the number five appears four times.
Thus, the numbers and
both appear the most amount of times, four times each! We have two modes!
Compare your answer with the correct one above
Consider the following set of numbers:
Find the mode of the set.
The mode of the set is the most repeated number in the set.
First organize the set in order from smallest to largest.
From here we can see more clearly when there is a repeated number.
In this case that number is because all other number only occur once.
Compare your answer with the correct one above
Consider the following set of numbers:
Find the mode of the set.
The mode of the set is the most repeated number in the set. In this case there is number being repeated once and another being repeated twice.
Therefore the answer will be the number that is being repeated twice, .
This number can be seen in red.
Compare your answer with the correct one above
Consider the following set:
Find the mode of the set.
The mode of the set is the number that occurs the most times in the set.
In this case that number is since all other numbers are only seen once in the data set.
