Study Notes

Arithmetic Mean in Statistics

The arithmetic mean, often called the average, is a measure of central tendency in statistics. It represents the typical value in a dataset.
The arithmetic mean is important because it provides a single value that summarizes the entire dataset, making it easier to understand the overall trend or distribution.
It is calculated by summing all the values in the dataset and then dividing by the total number of values.
In numerical calculations, the arithmetic mean is used to find the average of a set of numbers.
The arithmetic mean, median, and mode are all measures of central tendency but differ in their calculations and interpretations:
- The arithmetic mean is the sum of all values divided by the total number of values.
- The median is the middle value when the dataset is ordered from least to greatest.
- The mode is the value that appears most frequently in the dataset.
In real-life applications, the arithmetic mean can be used to calculate average income, average temperature, average test scores, or average customer satisfaction ratings.
