Example Question #141 : How To Find Mode

A test was given to a class of students. Three students scored , two scored , one scored , two scored and two scored . What was the modal score of the class? 

Possible Answers:

Correct answer:

Explanation:

Modal score or mode of this score set is the score that repeats itself the highest number of times. Here  repeats itself  three times. The other scores repeat themselves at most two times. Hence  is the modal score of the class.

Example Question #511 : Statistics And Probability

A test was given to a class of students. Three students scored , three scored , three scored and two scored . What was the modal score (mode) for this test for this class? 

 

Possible Answers:

There is no mode for this set.

Correct answer:

Explanation:

 is definitely incorrect because it occurs only twice while  and occur thrice. Since  occur thrice and mode is the data point that repeats the most, hence  are all modes or modal scores.

Example Question #512 : Statistics And Probability

Find the mode of the data set:

Possible Answers:

Correct answer:

Explanation:

The mode is defined as the highest frequency of a number or numbers in a data set.

Each number in the given set has a frequency of one.

This means that there is no mode.

The answer is: 

Example Question #153 : How To Find Mode

Find the mode of the data set:  

Possible Answers:

Correct answer:

Explanation:

The mode is defined as the highest occurrence of numbers in a given set of data.

The numbers that occur three times in the given set of data are:  

The numbers that occur twice in the data set are not the highest occurrence of numbers.

The answer is:  

Example Question #513 : Statistics And Probability

Find the mode:  

Possible Answers:

Correct answer:

Explanation:

The mode is the number or numbers that has the highest occurrence in a dataset.

The only number that occurs more than once is seven.

Every other number in the given set of data only has an occurrence of one.

The answer is:  

Example Question #514 : Statistics And Probability

Find the mode of the data set:  

Possible Answers:

Correct answer:

Explanation:

The mode is the highest frequency of numbers that occur set of data.  

Do not count individual ones, tens, and hundreds digits as the frequency of occurrence. 

Since each number occurs only once, there is no mode.

The answer is:  

Example Question #515 : Statistics And Probability

Find the mode of the set of data:  

Possible Answers:

Correct answer:

Explanation:

The mode is defined as the highest frequency of number or numbers in the given set of data.

The highest frequency of numbers are zero, two, and four, since they appear twice in the set.

The answer is:  

Example Question #516 : Statistics And Probability

The test scores for a science test are as follows:

What is the mode?

Possible Answers:

Correct answer:

Explanation:

The mode is the number that occurs most often in a data set.

Because 90 appears three times--and no other number occurs as many times--90 is the mode.

Example Question #517 : Statistics And Probability

The batting averages of the starting lineup for a baseball team are as follows:

What is the mode?

Possible Answers:

None

Correct answer:

None

Explanation:

The mode is the number that occurs most often in a data set.

Because each batting average occurs only once, there is no mode.

Example Question #518 : Statistics And Probability

The average daily temperatures for the last week in Miami are as follows:

What is the mode?

Possible Answers:

Correct answer:

Explanation:

The mode is the number that occurs most often in a data set.

Because 80 appears three times and each other temperature occurs only once or twice, 80 is the mode.
