Reorder the data set in chronological order.

The mode is the most frequent number that appears in the set.  There can be more than one mode in a set.  The most common numbers are 1,3, and 5.

The correct answer is:  

The mode is the number in a set that appears the most often. Each number in the given series is only seen once. Therefore, the solution is that there is no mode for this sereis. 

The mode is the most commonly displayed number in the data set. Unlike the median, this is not based on position within the set, so no reordering is (strictly speaking) required. The number 200 occurs four times in the set, with no other number occurring this often. Therefore, the set is unimodal (has one mode), and the mode is 200.

The mode is the data value that appears the most often. In this set of data, each value appears only once, we have no numbers that are repeated. Thus, this data set has no mode, answer "none." 

Mode refers to the value in a data set that occurs most often in the set. We can see when we rearrange the set:

That there are two values occurring three times each. Both are the mode, thus the system is bimodal.

The mode is the piece of data that appears the most. In the set provided, each data piece appears once, all but the number  which appears twice. If this data were graphed on a histogram, the mode would be easily visualized as the bar, line, or point that reachest the highest value on the y-axis. 

To find the mode, we must find which number appears the most amount of times. (rememeber: mode = most!)

In this data set: 

,

the numbers  and  all only appear once. But the numbers  and  appear more than once; these are our candidates for the mode.

Let's go one number at a time. The number four appears four times; the number two appears two times; the number five appears four times.

Thus, the numbers  and  both appear the most amount of times, four times each! We have two modes!

The mode of a set of numbers is the number that occurs the most times.

Since 85 appears twice, and all other numbers appeared only once, 85 is the mode.

The mode is defined as the number that appears more than once. If the data was graphed onto a histogram, the mode would bet he bar, point, or line that reaches the highest y-value.

In this set of data, each number appears only once, thus there is no mode. The answer is "none."

The data set provided is: 

.

Before we try to find the median and mode, place the numbers in numerical order, 

Since there is an odd amount of data,  pieces, we can subtract one and then divide the result in half, . This means that there must be four pieces of data on either side of the median. To satisfy this requirement the median then must be .

The mode is just the number that appears the most. It is possible to have more than one mode. In this set of data, our modes are  and , both numbers appear twice.
