In mathematics, the mean is a measure of central tendency that represents the average of a group of numbers. It is commonly referred to as the “arithmetic mean”. To find the mean, you add up all the values in a dataset and divide the sum by the total number of values.
Mathematically, the mean is calculated using the following formula:
Mean = (sum of all values) / (total number of values)
For example, let’s say we have a dataset of numbers: 5, 7, 10, 12, and 15. To find the mean of these numbers, you would add them all together: 5 + 7 + 10 + 12 + 15 = 49. Since there are 5 numbers in the dataset, you would then divide the sum by 5: 49 / 5 = 9.8. Therefore, the mean of this dataset is 9.8.
The mean is widely used in various fields, including statistics, economics, and science. It is useful because it provides a single numerical value that summarizes the entire dataset. However, it is important to note that the mean is sensitive to extreme values, also known as outliers, which can significantly affect the overall value.
