January 26, 2005 - In statistics, the mode is the value that appears most often in a set of data values. If X is a discrete random variable, the mode is the value x at which the probability mass function P(X) takes its maximum value, i.e., x = argmaxxi P(X = xi).

Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers. The mode is the number in a data set that occurs most frequently.
People also ask

How do I find the mode?
To find the mode: ยท If your data is numerical or quantitative, order the values from low to high. ยท If it is categorical, sort the values by group, in any order. ยท Then you simply need to identify the most frequently occurring value.

Can there be more than one mode?
A data set can often have no mode, one mode or more than one mode โ€“ it all depends on how many different values repeat most frequently. ยท Your data can be: ยท without any mode ยท unimodal, with one mode, ยท bimodal, with two modes, ยท trimodal, with three modes, or ยท multimodal, with four or more modes.

What are measures of central tendency?
Measures of central tendency help you find the middle, or the average, of a data set. ยท The 3 most common measures of central tendency are the mean, median and mode. ยท The mode is the most frequent value. ยท The medianis the middle number in an ordered data set. ยท The mean is the sum of all values divided by the total number of values.

Suppose you have a set of numbers like: 1, 2, 2, 4, 5, 6, 6, 6, 7. The mean (which is 4.33...) tells you what the arithmetic average number of your set of numbers is. The mean is highly sensitive to "outliers." Meaning, if you have a fairly large number (and the rest of your numbers are small or vice versa, really), it greatly affects the mean. Check it: take a set of numbers like 1, 2, 3. Find its mean (the mean is 2). Then check the mean of 1, 2, 3, 94. You'll get 25. It drastically changed the value! The median tells you what number lies in the middle of your set of numbers. So in this case, the number 5 is the middle number (there are four numbers to the left and four numbers to the right). The median can be fairly deceptive when working with these types of problems because you could have 1, 3, 100 as your set of numbers, in which case 3 would be the median. Knowing that 3 is the median here doesn't tell you too much other than that it's in the middle. The mode is a bit nicer in that it's just the most common number in your set of numbers, so in this case we'd get a mode of 6. Even mode has a drawback: what if all of your numbers only show up once? Well, you didn't really learn anything new about the set of numbers. Each of these has its drawback, but sometimes you can extract information like: what is the "most likely" number to be picked out of our set of numbers? The mode. Or if I kept picking numbers, what would be their average value? The mean. Or if I lined up the numbers, what number is in the middle? The median. At first glance, the mode is the one that is most applicable, and often the utility of these three make a lot more sense when dealing with probability functions (like when dealing with what is known as the Maxwell-Boltzmann distribution ). Edited for a little clarity.

One advantage of the mode is that it can be used for qualitative data (e.g., political alignments) where mean and median don't make sense.

Mean, Mode and Median - Measures of Central Tendency - When to use with Different Types of Variable and Skewed Distributions | Laerd Statistics
The mean is being skewed by the two large salaries. Therefore, in this situation, we would like to have a better measure of central tendency. As we will find out later, taking the median would be a better measure of central tendency in this situation. Another time when we usually prefer the median over the mean (or mode) is when our data is skewed (i.e., the frequency distribution for our data is skewed).

4.4.3 Calculating the mode
Looking at the table and histogram, you can easily identify the modal-class interval, 160 to 179 centimetres, whose frequency is 480. You can also see that as the height decreases from this interval, the frequency also decreases for the interval 140 to 159 centimetres (363) and it continues to decrease for 120 to 139 centimetres (168), before starting to increase until the height reaches 80 to 99 centimetres (230). For categorical or discrete variables, multiple modes are values that reach the same frequency: the highest one observed.
