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:

Example Question #487 : Statistics And Probability

Find the mode:  

Possible Answers:

Correct answer:

Explanation:

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

There are fractions that are not fully reduced.  Simplify those fractions and rewrite the dataset.

We can now see that  has the highest frequency of occurrence.

The answer is:

Example Question #131 : How To Find Mode

Which dataset has no mode?

Possible Answers:

Correct answer:

Explanation:

The mode of a dataset is the element that occurs the most frequently. A set is considered to have no mode if and only if no element is repeated. The only choice that fits this description is

.

Example Question #132 : 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:

Five

The correct answer is not among the other choices.

Infinitely many

One

Zero

Correct answer:

Zero

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.

Each of the five known elements are unique within the set. If the square is replaced by one of those five numbers, then that element will appear twice, and each other element will appear once. That will give the set exactly one mode. If the square is replaced by any other number, then each number will appear exactly once, and the set will have no mode. Therefore, there is no number that can replace the square that will make it bimodal.

Example Question #133 : 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:

Infinitely many

Two

Three

One

None

Correct answer:

Infinitely many

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" or a "4", then that number will appear in the set three times, more than any other number. The set will have exactly one mode. If the square is replaced by "6", then each of "2", "4", and "6" will appear two times, giving the set three modes.

However, if any other number replaces the square, "2" and "4" will each appear twice, and "6" and the new number will each appear once. This makes "2" and "4" the two modes of the set. The correct response is therefore infinitely many.

Example Question #134 : How To Find Mode

Consider the data set

.

How many ways can a single number replace the square to create a set with no mode?

Possible Answers:

Three

Infinitely many

Four

One

Zero

Correct answer:

Zero

Explanation:

The mode of a dataset is the element that occurs the most frequently. A set is considered to have no mode if and only if no element is repeated. However, the element "1" already occurs twice, so there is no number that can be written in the box that will create this condition.
