Mean-Median-Mode Calculator

Data worths (separated through commas, maximum 50 values): * 124,272,238,114,281,123,133,149,261,274,126,124



The average of a data set is commonly known as the average. You uncover the average by taking the amount of all the data values and also dividing that amount by the total number of data values. The formula because that the median of a populace is $$ \mu = \frac\sumxN $$ The formula for the median of a sample is $$ \barx = \frac\sumxn $$ Both of these formulas usage the very same mathematical process: discover the sum of the data values and also divide by the total. Because that the data values gotten in above, the equipment is: $$ \frac221912 = 184.9167$$


The average of a data set is uncovered by placing the data set in ascending numerical order and also identifying the center number. If there room an odd variety of data values in the data set, the median is a single number. If there room an even variety of data worths in the data set, the mean is the average of the two center numbers. Sorting the data collection for the worths entered above we have:

$$ 114, 123, 124, 124, 126, 133, 149, 238, 261, 272, 274, 281$$

due to the fact that there is an even number of data worths in this data set, there room two center numbers. Through 12 data values, the center numbers space the data worths at positions 6 and 7. These are 133 and 149. The median is the average of this numbers. We have actually $$ \frac 133 + 149 2 $$ Therefore, the mean is $$ 141 $$


The mode is the number that appears most frequently. A data set may have multiple modes. If it has two modes, the data collection is dubbed bimodal. If every the data values have actually the same frequency, all the data values are modes. Here, the mode(s) is/are

How to usage the Mean typical Mode Calculator

This mean typical mode calculator finds the procedures of main tendency. First, the calculator will give you an answer, and also then the will overview you through a step-by-step solution to conveniently learn exactly how to perform the trouble yourself. The mean is the average of a set of numbers. The mean is the center number/s when arranged in number order. Lastly, the mode is the number that shows up most often.

You are watching: 94+90+96+96


Once you’ve perfect calculating procedures of main tendency, go and take a look at the Range, Variance, and Standard Deviation Calculator. Statistics has never to be easier… You gained this!

What room Mean average Mode?

The mean, median, and also mode are the measures of central tendency in statistics. In other words, they room numbers the we use to measure and also describe the center of a distribution. When students begin learning around distributions in statistics courses, instructors and also textbooks teach the mean, median and also mode as several of the an initial topics in the course. Also elementary institution teachers introduce their college student to steps of central tendency, so elementary school students have the right to use the Mean median Mode Calculator too. Here, we’ll explore how to uncover the typical median and mode through hand. Then, you can use the mean typical mode calculator to inspect your work.

How to uncover the Mean

The average is commonly what we know as the average that a collection of numbers. Most students are really familiar v averages and also often use them come determine how they are performing in a class. Just how do you discover the typical in math? We find the median by adding up every the number of the data set, then separating by the total variety of values.

$$ \textmean = \frac\sum\textdata values\texttotal $$

In math, we usage the summation symbol, $\sum$, to note that us should add all the numbers together.

If you room studying AP statistics, college-level statistics, or something past middle school mathematics, then, you’ll use details symbols to represent the mean. Symbolically, you’ll represent the populace mean by “mu” $\mu$ and denote the populace size through N. You’ll represent the sample average by “x-bar” $\barx$ and also you’ll denote the sample size by n. The population mean formula is:

$$ \mu = \frac\sumxN $$

The sample average formula is:

$$ \barx = \frac\sumxn $$

In every of this formulas, x represents each of the number in the data set. So, $\sumx$ is the amount of all the data values.

Here is exactly how to discover the mean in the data collection 3, 5, 9, 15, 17. The population mean is

$$ \mu = \frac3 + 5 + 9 + 15+ 175 $$

$$ \mu = \frac495 = 9.8 $$

You deserve to use the Mean median Mode Calculator above and go into values of 3, 5, 9,15, 17 to verify the typical is 9.8.

How perform You find the Median?

What go the median mean in math? as soon as you arrange all the numbers of a data collection in raising numerical order, the mean is the number that falls specifically in the middle. If there space two number that autumn in the middle, the mean is the typical of these 2 numbers.

3, 5, 9, 15, 17

The typical of the data set above is 9. 9 is the number in the middle.

Now think about the complying with data set:

3, 5, 9, 15, 17, 20

How carry out you uncover the typical in this case? Here, we’ll require to discover the median of also numbers. To execute that, we take the median of the two center numbers. The average of this data collection is the median of 9 and 15. That is

$$ \frac9 + 152 = 12 $$

Now, usage the Mean average Mode Calculator over to inspect that the typical is now 12.

What is the Mode?

What walk the mode median in math? when describing a data set, the frequency the a data value is the number of times the data value occurs. The data value v the highest possible frequency, or the one the occurs most often, is the mode. A data set may have actually two settings if 2 numbers have actually the same greatest frequency. Us say that the distribution is bimodal if it has actually two modes. Sometimes, if over there are an ext than two numbers v the biggest frequency, we’ll say that the data set has no mode. However, through the Mean mean Mode Calculator above, the mode(s) found will include all the numbers v the biggest frequency.

In the data set 3, 5, 9, 15, 17, 9, what is the mode? The data worth 9 has a frequency that 2 while every the various other numbers have actually a frequency that 1. 9 has actually the greatest frequency and also therefore 9 is the mode. You can use theMean median Mode Calculator above to check that the setting is 9.

Mean Median and also Mode Examples

Here room some examples of typical median and mode in statistics.

Example 1: uncover the Mean

Find the populace mean that the data set: 85, 78, 92, 65


Since the trouble tells us to uncover the populace mean, the correct symbol to usage for the median is $ \mu $. The populace mean formula is

$$ \mu = \frac85 + 78 + 92 + 654 $$

$$ \mu = \frac 3204 = 80$$

Therefore, the population mean, $ \mu $, is 80.

You deserve to cut and paste this data collection into the Mean mean Mode Calculator above and verify that the typical is 80.

Example 2: discover the Median

Find the average for the complying with data set:

72, 75, 77, 80, 81, 81, 84, 86, 87, 88, 89, 91, 93, 94, 94, 94, 97, 99, 100

The typical is the middle number. Since there are 19 data values in this data set, the center number is the number in the 10th position. The is 88. The mean is 88.

Let’s include one much more data value to the beginning of the data collection to do a complete of 20 data values. We’ll include a 71.

71, 72, 75, 77, 80, 81, 81, 84, 86, 87, 88, 89, 91, 93, 94, 94, 94, 97, 99, 100

Since over there is one even set of data values, the mean is the average of the two center numbers. With 20 data values, the center two values space in positions 10 and 11. These 2 numbers space 87 and 88. The average of 87 and also 88 is:

$$ \textmedian = \frac87 + 882 $$

$$ \textmedian = 87.5 $$

Therefore, the typical of this data set is 87.5.

You have the right to cut and also paste this data collection into the Mean average Mode Calculator above and verify that the median is 87.5.

Example 3: find the Mode

71, 72, 75, 77, 80, 81, 81, 84, 86, 87, 88, 89, 91, 93, 94, 94, 94, 97, 99, 100

The setting is the data worth that appears most often. That is the data value with the greatest frequency. In this data set, the data value 94 has actually a frequency of 3, i beg your pardon is better than the frequency of any other data value. Therefore, the setting is 94.

You can cut and paste this data set into the Mean average Mode Calculator over and verify that the mode is 94.

Mean vs. Median – What’s the an ext Typical measure of central Tendency?

Find the average with second Outlier Score

When we calculate the mean, we discover that the outlier significantly affects the answer. An outlier in a data set is a value that is much lower or much higher than every the various other values. Let’s look at an instance of test grades. Expect the data worths in instance 1 over represent 4 check grades.

85, 78, 92, 65

We found the mean of this data collection to it is in 80. Now, think about a 5th test great of 20. Us would think about 20 an outlier since it is much smaller 보다 the rest of the test grades.

85, 78, 92, 65, 20

So, what’s the typical now?

$$ \mu = \frac85 + 78 + 92 + 65 + 205 $$

$$ \mu = \frac 3405 = 68 $$

Therefore, the brand-new mean is 68. An typical that alters from 80 come 68 is a great difference. The outlier worth of 20 substantially affects the mean. Do you think the score 68 represents a usual value in this data set?

Find the mean with secondary Outlier Score

If us were to order the original 4 test grades and also find the median, we’d calculation it to be the mean of 78 and also 85.

65, 78, 85, 92

$$ \textmedian = \frac78 + 852 $$

$$ \textmedian = \frac1632 = 81.5 $$

Therefore, the median for the original 4 test grades is 81.5.

Now, let’s encompass a fifth test class of 20 come the data set and find the brand-new median. For this reason now, ours data set is

20, 65, 78, 85, 92

With one odd variety of data values, the average is the center number. Here’s that worth is 78. So, the new median with the contained outlier is 78.

So what go this mean? The mean and also median for the original data set were, respectively, 80 and 81.5. Yet when we contained an outlier in the data set, the mean and median came to be 68 and 78. When the mean lessened 12 points with the contained outlier, the median decreased 3.5 points. We view that the outlier significantly affects the the mean, but the outlier just slightly influence the median. Therefore, us say that the median an ext accurately describes the typical test grade because it is more resistant (not together affected) to any outliers in the data set.

Positions of the typical Median and also Mode on miscellaneous Distributions

For Normal, Bell-Shaped Distributions

The mean, median, and mode are all approximately in the center of a normal, bell-shaped distribution. Therefore, we deserve to estimate the they all have the same value.

The typical median and also mode space all the exact same value ~ above a regular bell-shaped distribution.

Here is an example of a data set that has actually the exact same mean, median and mode. You have the right to verify that the actions of central tendency are all the very same by pasting this data collection into the Mean mean Mode Calculator.

1, 2, 2, 3, 3, 3, 4, 4, 4, 4, 5, 5, 5, 5, 5, 6, 6, 6, 6, 7, 7, 7, 8, 8, 9

For it was crooked Left, or Negatively it was crooked Distributions

In skewed left, or negatively skewed, distributions, there room low scores top top the left side of the distribution, possibly outliers, and also they pull the left tail the end to the left. Together we observed in the instance above, outliers greatly impact the mean, while outliers slightly impact the median. The setting remains the data value through the highest possible frequency. Therefore, outliers execute not impact the mode.

If we look at a photo of a it was crooked left distribution, we ar the mean in a place furthest to the left. Then, we placed the median in a position somewhere in the middle of the mean and also the mode. Finally, we placed the mode at a place where we check out the highest possible peak of the graph, since it is the worth of biggest frequency. This is a visual example of exactly how the median is most affected by outliers, the typical is slightly affected by outliers, and also the setting is not influenced by outliers. Therefore, the order of the 3 values along the horizontal axis space mean, climate median, then mode.

The position of the mean median and mode on a skewed left distribution. The median is pulled out to the left in the direction the the it was crooked tail.

For it was crooked Right, or Positively skewed Distributions

When a circulation is skewed to the right, or positive skewed, there room high scores on the right side of the distribution, perhaps outliers, dragging the appropriate tail out to the right. Just like the skewed left distribution, the median is greatly affected by outliers, if the mean is contempt affected. The mode is not impacted by outliers.

If us look in ~ a picture of a skewed right distribution, the average will it is in positioned furthest to the right. It’s value is being pulled in the direction of the it was crooked tail. Because the outliers in the ideal tail just slightly affect the median, it will certainly be positioned somewhere in the center of the mean and the mode. And again, the setting will be positioned at the highest possible peak the the graph, the position of biggest frequency. Therefore, the bespeak on the horizontal axis that the 3 values room mode, median, and mean.

The position of the mean median and also mode on a skewed right distribution. The typical is pulled the end to the best in the direction the the it was crooked tail.What’s Next?

The Mean average Mode Calculator over guides you v calculating the three procedures of central tendency. The following step is to build an understanding of the actions of variability. There room three steps of variability, the range, variance, and also standard deviation. That these, the traditional deviation will existing itself extensively throughout a university level statistics course.
