Example Question #1883 : Algebra 1

Find the mode of the following dataset: [76,36,26,16,6,66]

Possible Answers:

$\textup{No mode.}$

$\textup{All the numbers in the set.}$

Correct answer:

$\textup{No mode.}$

Explanation:

The mode is the number or numbers with the highest occurrence in a dataset.

There are no numbers in this dataset that have an occurrence more than once.

Do not confuse mode with the amount of times a particular unit digit shows up.

The answer is: $\textup{No mode.}$

Example Question #1881 : Algebra 1

Find the mode of the following data set:

16,77,83,16,23,99,55,77,23,16

Possible Answers:

Correct answer:

Explanation:

Find the median of the following data set:

16,77,83,16,23,99,55,77,23,16

Whenever we are working with a data set, it can be helpful to put the terms in order:

16,16,16,23,23,55,77,77,83,99

Now that our terms are in order, we can do all sorts of things with them.

In this case, we need the mode.

The mode is simply the most repeated term in the sequence.

With our terms in order it should be pretty clear that our mode is 16

Example Question #1892 : Algebra 1

Find the mode: $[25\%, \frac{1}{2}, 0.75, 1.25, \frac{5}{4}]$

Possible Answers:

$\textup{There is no mode.}$

$25\%$

0.5

0.75

1.25

Correct answer:

1.25

Explanation:

The mode is defined as the numbers that have the highest frequency.

The numbers will need to be converted to a common form. Let's choose decimal.

$25\% = 0.25$

$\frac{1}{2} = 0.5$

$\frac{5}{4}= 1.25$

Rewrite the dataset.

$[25\%, \frac{1}{2}, 0.75, 1.25, \frac{5}{4}] = [0.25,0.5,0.75,1.25,1.25]$

We will notice that 1.25 has the highest frequency.

The answer is: 1.25

Example Question #104 : How To Find Mode

Find the mode of the following data set:

1, 3, 6, 4, 1, 6, 1, 7, 11

Possible Answers:

4.4

Correct answer:

Explanation:

The mode of a data set is the number that appears the most frequently. Given the data set

1, 3, 6, 4, 1, 6, 1, 7, 11

the number that appears most frequently is 1. Therefore, the mode is 1.

Example Question #1894 : Algebra 1

Find the mode of the following dataset: $[9,0.99,99,19,3,\frac{9}{10}]$

Possible Answers:

$\textup{All the numbers in the set can be the mode.}$

3,19

$\textup{No mode.}$

Correct answer:

$\textup{No mode.}$

Explanation:

The mode is the number or numbers with the highest occurrence in a dataset.

Notice that many numbers in the dataset share common numbers of nine, but each of the six numbers in the set are independent numbers.

There are no numbers in this dataset that have more than one occurrence, which means there is no mode.

The answer is: $\textup{No mode.}$

Example Question #105 : How To Find Mode

Find the mode of the following data set:

4, 2, 7, 8, 8, 2, 8, 10, 7

If necessary, round your answer to the nearest whole number.

Possible Answers:

Correct answer:

Explanation:

To find the mode of a data set, you determine which number appears most frequently. Given the data set

4, 2, 7, 8, 8, 2, 8, 10, 7

the number 8 appears the most often (3 times). Therefore, 8 is the mode.
