Example Question #552 : Isee Middle Level (Grades 7 8) Mathematics Achievement

You roll a dice 10 times.  Here are your results:

\(\displaystyle 4, 2, 5, 1, 3, 2, 5, 6, 1, 5\)

Find the mode.

Possible Answers:

\(\displaystyle 2\)

\(\displaystyle 4\)

\(\displaystyle 5\)

\(\displaystyle 6\)

\(\displaystyle 1\)

Correct answer:

\(\displaystyle 5\)

Explanation:

To find the mode of a data set, we will find the number or result that appears most often.

So, given the set

\(\displaystyle 4, 2, 5, 1, 3, 2, 5, 6, 1, 5\)

we can see the number 5 appears most often (it appears 3 times). 

Therefore, the mode of the data set is 5.

Example Question #553 : Isee Middle Level (Grades 7 8) Mathematics Achievement

A Science class took an exam.  Here are their scores:

\(\displaystyle 76, 82, 90, 85, 91, 75, 83, 88, 92, 88, 74\)

Find the mode score.

Possible Answers:

\(\displaystyle 92\)

\(\displaystyle 91\)

\(\displaystyle 85\)

\(\displaystyle 76\)

\(\displaystyle 88\)

Correct answer:

\(\displaystyle 88\)

Explanation:

To find the mode score, we will find the number that appears most often.  So, given the data set

\(\displaystyle 76, 82, 90, 85, 91, 75, 83, 88, 92, 88, 75\)

we can see that 88 appears most often (it appears 2 times).

 

Therefore, the mode score is 88.

Example Question #241 : Data Analysis And Probability

Use the following data set to answer the question:

\(\displaystyle 6, 4, 7, 2, 5, 1, 4, 8, 4, 1\)

Find the mode.

Possible Answers:

\(\displaystyle 1\)

\(\displaystyle 5\)

\(\displaystyle 4\)

\(\displaystyle 7\)

\(\displaystyle 8\)

Correct answer:

\(\displaystyle 4\)

Explanation:

To find the mode, we will find the number that appears most often.  

So, given the set

\(\displaystyle 6, 4, 7, 2, 5, 1, 4, 8, 4, 1\)

we can see the number that appears most often is 4 (it appears 3 times).

 

Therefore, the mode of the data set is 4.

Example Question #554 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Find the mode.

Possible Answers:

\(\displaystyle 7\)

\(\displaystyle 8\)

\(\displaystyle 6\)

\(\displaystyle 1\)

\(\displaystyle 5\)

Correct answer:

\(\displaystyle 6\)

Explanation:

To find the mode, we will find the number that appears most often. 

So, given the set

\(\displaystyle 5, 2, 6, 1, 7, 5, 8, 6, 4, 6, 9\)

we can see the number that appears most often is 6 (it appears 3 times).

 

Therefore, the mode of the data set is 6.

Example Question #555 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Use the following data set to answer the question:

\(\displaystyle 4, 3, 7, 5, 9, 6, 7, 2, 7, 2, 10, 7\)

Find the mode.

Possible Answers:

\(\displaystyle 8\)

\(\displaystyle 3\)

\(\displaystyle 5\)

\(\displaystyle 7\)

\(\displaystyle 4\)

Correct answer:

\(\displaystyle 7\)

Explanation:

To find the mode of a data set, we will find the number the appears most often.  So, given the set

\(\displaystyle 4, 3, 7, 5, 9, 6, 7, 2, 7, 2, 10, 7\)

we can see the number that appears most often is 7 (it appears 4 times).

Therefore, the mode of the data set is 7.

Example Question #241 : Data Analysis And Probability

Use the following data set to answer the question:

Example Question #551 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Determine the mode of the numbers:  \(\displaystyle [-1,-1,-2,3,4,5,5,-6]\)

Possible Answers:

\(\displaystyle -6,-2,3,4\)

\(\displaystyle \frac{7}{8}\)

\(\displaystyle -1,5\)

\(\displaystyle 5\)

\(\displaystyle 2\)

Correct answer:

\(\displaystyle -1,5\)

Explanation:

The mode includes all numbers that have the highest frequency.

The numbers that occur more than once are:  \(\displaystyle -1,5\)

All of the other numbers occur only once.

The answer is:  \(\displaystyle -1,5\)

Example Question #561 : Isee Middle Level (Grades 7 8) Mathematics Achievement

What is the mode in this number set?

 \(\displaystyle \small 4, 3, 5, 6, 6, 7, 4, 2, 1, 4, 6, 3 ,4 ,10, 4\)

Possible Answers:

\(\displaystyle 5\)

\(\displaystyle 6\)

\(\displaystyle 4\)

\(\displaystyle 3\)

\(\displaystyle 2\)

Correct answer:

\(\displaystyle 4\)

Explanation:

The mode is the number that appears most often in the number set.

In this number set, there are five 4's, making 4 the mode.
