Example Question #135 : How To Find Mode

Consider the data set

How many ways can a single number replace the square to create a bimodal set?

Possible Answers:

Three

Infinitely many

One

Zero

Two

Correct answer:

Two

Explanation:

The mode of a dataset is the element that occurs the most frequently. A set is considered to be bimodal if there are two elements that tie for this distinction.

If the square is replaced by a "2", then the set will comprise four "2's", two "3's", and two "4's". This will make 2 the only mode.

If the square is replaced by a "3", then the set will comprise three "2's", three "3's", and two "4's", making the set one with two modes, 2 and 3. Similarly, if the square is replaced by a "4", 2 and 4 will be the modes. Either of these two ways will make the set bimodal.

If the square is replaced by any other number, the set will comprise three "2's", two "3's", two "4's", and one other number, making 2 the only mode.

Therefore, there are two ways to replace the square to form a bimodal set.

Example Question #136 : How To Find Mode

What is the mode of the set of data?  

Possible Answers:

Correct answer:

Explanation:

The mode is the highest frequency of a number or numbers in a dataset.

There are 2 ones, 2 twos, and 1 three in the set of data.

Therefore, the mode is one and two.

The answer is:  

Example Question #498 : Statistics And Probability

Find the mode:  

Possible Answers:

Correct answer:

Explanation:

The mode is the highest frequency of numbers in a dataset.  In the given dataset, we notice that the  will round to , and  is very similar to .

But the true values of the  and  terms are irrational numbers.  This means that every term in the dataset has only one occurrence.

The correct answer is:  

Example Question #499 : Statistics And Probability

Find the mode of the following set:

Possible Answers:

Correct answer:

Explanation:

To find the mode of any set, find the number which occurs the greatest number of times in the set.  

 

2 occurs 6 times and 22 occurs 5 times

Therefore two is the mode.

Example Question #500 : Statistics And Probability

Find the mode of the following set:

Possible Answers:

Correct answer:

Explanation:

To find the mode of any set, find the number which occurs the greatest number of times in the set.  

Since 5 occurs two times and all other values only occur once, five is the mode.

 

Example Question #501 : Statistics And Probability

Find the mode of the following set:

Possible Answers:

Correct answer:

Explanation:

To find the mode of any set, find the number which occurs the greatest number of times in the set.  

Since zero occurs two times while all other values occur once that means the mode is .

Example Question #1922 : Algebra 1

Find the mode of the following set:

Possible Answers:

Correct answer:

Explanation:

To find the mode of any set, find the number which occurs the greatest number of times in the set.  

 

2 occurs 3 times

3 occurs 4 times

4 occurs 3 times

5 occurs 1 time

Therefore the mode is: 

Example Question #141 : How To Find Mode

Find the mode:   

Possible Answers:

Correct answer:

Explanation:

The mode is the highest frequency of the number or numbers in a dataset.

Simplify all terms in the dataset.

Both the numbers two and three occur in the dataset twice, while the other numbers occur in the dataset once.

The answer is:  

Example Question #141 : How To Find Mode

Find the mode of the following set:

Possible Answers:

Correct answer:

Explanation:

To find the mode of any set, find the number which occurs the greatest number of times in the set.  The best answer is five.

Example Question #142 : How To Find Mode

Find the mode of the following set:

Possible Answers:

Correct answer:

Explanation:

To find the mode of any set, find the number which occurs the greatest number of times in the set.  The best answer is eight.
