Example Question #211 : Data Analysis

Find the mode of the following set of values:

Possible Answers:

Correct answer:

Explanation:

The mode of a set is the value that occurs the most frequently.  In this set that value is  as it occurs four different times.

Example Question #521 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Find the mode of the following data set:

Possible Answers:

Correct answer:

Explanation:

Find the mode of the following data set:

First, let's rearrange our numbers in increasing order:

Next, identify the mode by identifying the number which appears most often. 

 

In this case, it is 12, because we have 3 12's, and no other number appears more than twice.

Example Question #522 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Use the following data set to answer the question.

Find the mode.

Possible Answers:

Correct answer:

Explanation:

To find the mode of a data set, we are looking for the number or value that appears most frequently.  So, looking at the set

we can see that the number  appears most often. 

 

Therefore, the mode of this data set is .

Example Question #522 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Find the mode of the following data set:

Possible Answers:

Correct answer:

Explanation:

Find the mode of the following data set:

First, let's put our set in increasing order:

Next, identify the mode by identifying the number which appears most often.

In this case, we have two 27's, and no other doubles. This means that 27 is our mode.

 

Example Question #524 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Use the following data set to answer the question:

Find the mode.

Possible Answers:

Correct answer:

Explanation:

To find the mode of a data set, we must determine the number within the set that occurs most frequently or most often.  So, looking at the data set

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

 

Therefore, the mode of the data set is .

Example Question #525 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Use the following set of data to answer the question.

Find the mode of the data set.

Possible Answers:

Correct answer:

Explanation:

To find the mode of a data set, we must find the number that occurs most frequently within the set.  So, in the set

we can see that the number 7 appears most frequently (3 times).  

Therefore, the mode of the data set is .

Example Question #523 : Isee Middle Level (Grades 7 8) Mathematics Achievement

What is the mode of the following data set?

Possible Answers:

Correct answer:

Explanation:

What is the mode of the following data set?

First, put the data set in increasing order:

Next, simply look for the value which is most often repeated:

We have three 145's two 678's, and two 902's

The answer must be 145

Example Question #527 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Use the following data set to answer the question.

Find the mode.

Possible Answers:

Correct answer:

Explanation:

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

So, given the data set

we can see that the number that appears most frequently is .

 

Therefore, the mode of the data set is .

Example Question #524 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Find the mode of the following data set:

Possible Answers:

Correct answer:

Explanation:

Find the mode of the following data set:

Let's begin by ordering our data set from least to greatest.

Now, the mode is simply the most common number. In this case, it is 45 because we have 3 45's

 

Example Question #525 : Isee Middle Level (Grades 7 8) Mathematics Achievement

Find the mode of the following data set:

Possible Answers:

Correct answer:

Explanation:

Find the mode of the following data set:

First, let's reorder our data set:

The mode can be easily identified by looking for the most common number.

In this case, we have 3 23's and 2 45's. So, 23 must be our mode.
