## How To Find The Mean Median And Mode: Median

If you had an odd number in step 3, go to step 5. If you had an even number, go to step 6.

**Step 5:***Find the number in the middle of the series.*This is the**median**. 2, 19, 44, 44, 44,**51**,56, 78, 86, 99, 99.**Step 6:***Find the middle two numbers.*For example, 1, 2, 5, 6, 7, 8, 12, 15, 16, 17. The**median**is the number that comes in the middle of those middle two numbers , so that number would be 7.5 in this case. .

**Tip:**; You can have more than one mode. For example, the mode of 1, 1, 5, 5, 6, 6 is 1, 5, and 6.

## Relation Between Mean Median And Mode

The three measures of central values i.e. mean, median, and mode are closely connected by the following relations .

2Mean + Mode = 3Median

For instance, if we are asked to calculate the mean, median, and mode of continuous grouped data, then we can calculate mean and median using the formulas as discussed in the previous sections and then find mode using the empirical relation.

For example, we have data whose mode = 65 and median = 61.6.

Then, we can find the mean using the above mean, median, and mode relation.

2Mean + Mode = 3 Median

Mean = 59.9

## Advantages Of Using Mode

In certain cases, mode can be an extremely helpful measure of central tendency. One of its biggest advantages is that it can be applied to any type of data, whereas both the mean and medianMEDIAN FunctionThe MEDIAN Function is categorized under Excel Statistical functions. The function will calculate the middle value of a given set of numbers. Median can be defined as the middle number of a group of numbers. That is, half the numbers return values that are greater than the median cannot be calculated for nominal data. It is also not affected by extreme values in datasets with quantitative dataQuantitative AnalysisQuantitative analysis is the process of collecting and evaluating measurable and verifiable data to understand the behavior and performance of a business.. Thus, it can provide the insights into almost any dataset despite the data distribution.

On the other hand, the statistical measure also comes with its own limitations. For instance, it cannot be further treated mathematically. Therefore, the measure cannot be used for more detailed analysis. In addition, since it is not based on all values in the dataset, it is difficult to draw conclusions regarding the dataset relying on mode only.

## Using Mode To Identify A Base Line

The mode is the number that occurs most often within a set of numbers. For the server power consumption examples above, there is no mode because each element is different. But suppose the administrator measured the power consumption of an entire network operations center and the set of numbers is 90 W, 104 W, 98 W, 98 W, 105 W, 92 W, 102 W, 100 W, 110 W, 98 W, 210 W and 115 W. The mode is 98 W since that power consumption measurement occurs most often amongst the 12 servers. Mode helps identify the most common or frequent occurrence of a characteristic. It is possible to have two modes , three modes or more modes within larger sets of numbers.

## Examples Of How To Find The Mean Median Mode And Range

**Example 1:** Find the mean, median, mode and range for the following list of values

The mean is commonly known as the average which is calculated by getting the sum of all values in the list and then divided by the number of entries. The;symbol used to represent mean is \bar X, often read as x-bar.

**To find the mean:**

I rounded off the final answer to the nearest whole number because all the;numbers in the set are also whole numbers.;To be more specific, I rounded off the mean to the nearest ones place or digit.

Rounding off is an approximation so I use the wavy equal symbol \left to suggest that it is an estimate and not an exact answer. However, be proactive by asking your teacher how many decimal places to round off your final answer.

**To find the median:**

I must organize the numbers from lowest to highest, and identify the middle value.

; In addition, since the number count of entries is **odd**, it is guaranteed to have a middle value. A quick shortcut to determine which entry is the median is to add the number of entries by 1 then divide by 2. Use the output value here to count from either the left or right of the ordered list to pinpoint the exact location of the median.

From our previous problem, the number of count of elements in the set is x = 9 so we have

Therefore, the median is located by finding the **5th entry** when counted from either the left or right of the ordered list.

## Using Range To Identify Outliers

The range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set. If a six-server rack includes 90 W, 98 W, 100 W, 102 W, 105 W and 110 W, the power consumption range is 110 W – 90 W = 20 W.

Range shows how much the numbers in a set vary. Many IT systems operate within an acceptable range; a value in excess of that range might trigger a warning or alarm to IT staff. To find the variance in a data set, subtract each number from the mean, and then square the result. Find the average of these squared differences, and that is the variance in the group. In our original group of five servers, the mean was 99. The 100 W-server varies from the mean by 1 W, the 105 W-server by 6 W, and so on. The squares of each difference equal 1, 1, 36, 81 and 9. So to calculate the variance, add 1 + 1 + 36 + 81 + 9 and divide by 5. The variance is 25.6. Standard deviation denotes how far apart all the numbers are in a set. The standard deviation is calculated by finding the square root of the variance. In this example, the standard deviation is 5.1.;

## What Are Mean Median And Mode

Mean, median and mode are all measures of central tendency in statistics. In different ways they each tell us what value in a data set is typical or representative of the data set.

The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.

The median is the central number of a data set. 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. Count how many times each number occurs in the data set. The mode is the number with the highest tally. It’s ok if there is more than one mode. And if all numbers occur the same number of times there is no mode.

## How Are Mean Median Mode And Range Used In The Data Center

Understanding the definition of mean, median, mode and range is important for IT professionals in data center management.;Many relevant tasks require the administrator to calculate mean, median, mode or range, or often some combination, to show a statistically significant quantity, trend or deviation from the norm. Finding the mean, median, mode and range is only the start. The administrator then needs to apply this information to investigate root causes of a problem, accurately forecast future needs or set acceptable working parameters for IT systems.

When working with a large data set, it can be useful to represent the entire data set with a single value that describes the “middle” or “average” value of the entire set. In statistics, that single value is called the central tendency and mean, median and mode are all ways to describe it. To find the mean, add up the values in the data set and then divide by the number of values that you added. To find the median, list the values of the data set in numerical order and identify which value appears in the middle of the list. To find the mode, identify which value in the data set occurs most often. Range, which is the difference between the largest and smallest value in the data set, describes how well the central tendency represents the data. If the range is large, the central tendency is not as representative of the data as it would be if the range was small.

## Bimodal Trimodal & Multimodal

- When there are two modes in a data set, then the set is called
**bimodal**

For example, The mode of Set A = is 2 and 5, because both 2 and 5 is repeated three times in the given set.

- When there are three modes in a data set, then the set is called
**trimodal**

For example, the mode of set A = is 2, 5 and 8

- When there are four or more modes in a data set, then the set is called
**multimodal**
