Understanding Mean: Definition, Formula, Examples, and Comparison to Measures of Central Tendency
​When analyzing data, we often encounter various statistical measures that help us make sense of the information. One such measure is the mean, which provides valuable insights into the central tendency of a dataset. In this article, we will delve into the concept of mean, discuss its formula, provide examples with step-by-step calculations, and explore how it compares to other measures of central tendency.
Definition of Mean
The mean, also known as the arithmetic mean or average, is a statistical measure used to determine the central value of a dataset. It is obtained by summing up all the values in the dataset and then dividing the total by the number of data points.
Formula for Mean
The formula to calculate the mean is straightforward:
Mean = Sum of all values / Number of values
To compute the mean, follow these steps:
Example 1: Let's consider a simple example to illustrate the calculation of the mean. Suppose we have a dataset of test scores: 85, 90, 92, 88, and 95. To find the mean, we will follow the steps outlined above:
Step 1: Add up all the values: 85 + 90 + 92 + 88 + 95 = 450 Step 2: Count the total number of values: 5 Step 3: Divide the sum by the total number of values: 450 / 5 = 90
Therefore, the mean of the test scores is 90.
Example 2: Let's explore another example with a larger dataset. Consider the following set of numbers: 12, 14, 17, 19, 21, 23, 25, 28, 30, and 33. Following the mean calculation steps:
Step 1: Add up all the values: 12 + 14 + 17 + 19 + 21 + 23 + 25 + 28 + 30 + 33 = 222 Step 2: Count the total number of values: 10 Step 3: Divide the sum by the total number of values: 222 / 10 = 22.2
​
Hence, the mean of the given dataset is 22.2.
Mean = Sum of all values / Number of values
To compute the mean, follow these steps:
- Add up all the values in the dataset.
- Count the total number of values.
- Divide the sum by the total number of values.

Therefore, the mean of the test scores is 90.

​
Hence, the mean of the given dataset is 22.2.
Comparison to Measures of Central Tendency
The mean is just one of the several measures of central tendency. The two other common measures are the median and the mode.
​
To summarize, the mean is a valuable statistical measure for determining the central tendency of a dataset. It provides a concise average value that is easy to calculate. However, it is important to consider other measures like the median and mode, depending on the characteristics and distribution of the dataset.
- Median: The median represents the middle value of a dataset when arranged in ascending or descending order. Unlike the mean, it is not affected by extreme values or outliers. However, it can be computationally expensive to calculate for large datasets.
- Mode: The mode refers to the value that appears most frequently in a dataset. It is particularly useful for categorical or discrete data. A dataset can have one mode (unimodal) or multiple modes (multimodal). Unlike the mean, the mode can handle non-numeric data.
