Example Questions

Example Question #393 : Statistics And Probability

Using the data above, find the mode and the range. 

Possible Answers:

Correct answer:

Explanation:

Using the data provided, we can find the mode by finding the number that appears the most.

In this set we have three modes because three of the numbers appear twice,  .

For the range, all we do is subtract the lowest value from the highest value, 

Example Question #394 : Statistics And Probability

Using the data above, find the mode and the range. 

Possible Answers:

Correct answer:

Explanation:

Using the data set given, , we are asked to find the mode and the range.

Since there are only four pieces of data, and none of them appear more than once, we can conclude that there is no mode.

Range is defined as the difference between the highest and lowest value, 

Example Question #395 : Statistics And Probability

Using the data above, find the mode and the range. 

Possible Answers:

Correct answer:

Explanation:

To find the range, simply find the range interval between the highest and lowest value in the data set: 

, so 

 

To find the mode, we simply count how many times a data value appears.

In this set the number  appears eight times, the number  appears once, and the number  appears three times.

Thus, the number  is our mode. 

Example Question #396 : Statistics And Probability

Ten students compare their test scores. the scores are as follows:

Find the mode of the set of test scores.

Possible Answers:

Correct answer:

Explanation:

The mode is the number or score that appears most often. In this case it is , because  appears three times which is the most any one number appears.

Example Question #397 : Statistics And Probability

Using the data above, find the range and the mode. 

Possible Answers:

Correct answer:

Explanation:

When provided with the data set: 

,

the first thing we should do is quickly find the mode. The mode is the number that appears the most amount of times. In this set, all numbers of different, and only appear once. Thus, there is no mode.

To find the range we use the highest and the lowest numbers: 

,

thus this is the range. 

Example Question #401 : Statistics And Probability

Using the data provided, find the mode and the range. 

Possible Answers:

Correct answer:

Explanation:

Using the data provided: 

,

to find the mode we simply count up the amount of times that certain data pieces appear.

In this set,  appears once,  appears three times, and  appears three times.

Thus,  and  are both the modes.

The range is found by finding the interval between the highest and lowest data pieces: 

Example Question #402 : Statistics And Probability

What is the mode of the following set of numbers?

 

Possible Answers:

Correct answer:

Explanation:

We define mode as the number that appears most often in a set of numbers.

Examining the set above, we see that  appears the most times specifically, it appears three times. The most any other number appears in the set is two times and therefore the mode of the set is

Example Question #42 : How To Find Mode

What is the mode of the following set of numbers?

Possible Answers:

Correct answer:

Explanation:

We define mode as the number that appears most often in a set of numbers.

Examining the set above, we see that  appears four times in the data set. The most any other number appears in the set is the number  which appears only three times therefore  is the mode of the set. 

Example Question #43 : How To Find Mode

What is the mode of the following set of numbers?

Possible Answers:

Correct answer:

Explanation:

We define mode as the number that appears most often in a set of numbers.

If we arrange the set in ascending order it is easier to identify the mode.

Examining the set above, we see that  appears the most times and is therefore the mode of the set. 

Example Question #403 : Statistics And Probability

Consider the following set of numbers:

Find the mode of the set.

Possible Answers:

Correct answer:

Explanation:

The mode of the set is the most repeated number in the set.

First organize the set in order from smallest to largest.

From here we can see more clearly when there is a repeated number.

In this case that number is  because all other number only occur once.
