Example Questions

Example Question #651 : Isee Upper Level (Grades 9 12) Mathematics Achievement

The heights of the starting volleyball team for a high school are inches. Give the mode of this data set.

Possible Answers:

Correct answer:

Explanation:

The mode is the value that appears most often which is in this data set, because appears two times while all of the other values only appear one time.

Example Question #652 : Isee Upper Level (Grades 9 12) Mathematics Achievement

In the following set of scores find the mode:

 

 

Possible Answers:

 

Correct answer:

Explanation:

The mode is the value that appears most often or has more frequency in a given set of data. So in this problem, the mode is  which occurs most frequently.

Example Question #8 : Mode

Consider the data set .  If the data set has only one mode, how many possible values of  are there?

Possible Answers:

Infinitely many

Correct answer:

Explanation:

If  then the value of  is appears five times, more than any other element. This would give the set one mode.

If , then 4, 6, and the value of  would appear three times each, more than any other element. This would give the set three modes.

If  assumes any other value, then 4 and 6 would appear three times each, more than any other element. This would give the set two modes.

Therefore, there are only two values of  that would give the set one mode.

Example Question #7 : How To Find Mode

Consider the data set .  For the data set to have exactly two modes, what are all of the possible choices of ?

Possible Answers:

Correct answer:

Explanation:

If , then the value of  will occur in the set five times, more than any other element. This will give the set one mode.

If , then there will be three elements -   - that occur three times, more than any other element. This will give the set three modes.

If is any other number, then there will be two elements -  - that occur twice, more than any other number. This will give the set two modes. 

Therefore, , and any other value of  gives the set one mode.

 

Example Question #653 : Isee Upper Level (Grades 9 12) Mathematics Achievement

What is the mode of the following set of numbers?

Possible Answers:

Correct answer:

Explanation:

To determine the mode, you need to identify which number appears most frequently in the set of numbers.

In this set of numbers, the number 2 shows up three times, and no other number occurs three or more times. Thus, it is the only mode.

Example Question #654 : Isee Upper Level (Grades 9 12) Mathematics Achievement

What is the mode value in the set below?

Possible Answers:

Correct answer:

Explanation:

The first step is to convert the expressions in the set to their simplified forms. This gives us:

While the value of 4 appears twice, given that the value 3 appears 3 times, it is the mode in this set. 

Example Question #655 : Isee Upper Level (Grades 9 12) Mathematics Achievement

Find the mode of the following data set:

Possible Answers:

Correct answer:

Explanation:

Find the mode of the following data set:

Begin by putting your numbers in increasing order:

We can identify the mode simply by finding the most common term.

In this data set, we have two 67's. There are no other duplicate numbers, so we have our answer: 67

 

Example Question #656 : Isee Upper Level (Grades 9 12) 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 rearranging our terms from least to greatest:

Now, the mode will be our most common term. 

In this case, it is 76, because there are two 76's.

Example Question #657 : Isee Upper Level (Grades 9 12) 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 terms in increasing order:

Now, our mode will just be our most common term. In this case it is 33.

Example Question #658 : Isee Upper Level (Grades 9 12) 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 terms in ascending order.

Next, identify the mode by choosing the most common term.

In this case, we have 2 78's. Therefore, our mode is 78.
