Arithmetic Mean Formula Explained:

**Definition of Arithmetic Mean:**
The arithmetic mean, also known as the average, is a statistical measure used to determine the central tendency of a set of numbers. It is calculated by summing up all the numbers in the set and then dividing the sum by the total count of numbers.

**Formula for Arithmetic Mean:**
The formula for calculating the arithmetic mean is:

Arithmetic Mean = (Sum of all numbers) / (Total count of numbers)

**Step-by-Step Explanation:**

1. **Sum of all numbers:** To find the arithmetic mean between two digits, you need to start by adding the two digits together. For example, let's consider the numbers 7 and 9. The sum of these two numbers is 7 + 9 = 16.

2. **Total count of numbers:** Since we are finding the arithmetic mean between two digits, the total count of numbers is 2.

3. **Apply the formula:** Now, we can plug in the values into the arithmetic mean formula:

Arithmetic Mean = (Sum of all numbers) / (Total count of numbers)
Arithmetic Mean = 16 / 2
Arithmetic Mean = 8

Therefore, the arithmetic mean between the numbers 7 and 9 is 8.

**Importance of Arithmetic Mean:**
The arithmetic mean is commonly used in various fields, including mathematics, statistics, and economics. It provides a measure of the central tendency of a set of numbers, allowing us to understand the average value or typical value of a dataset. It is a useful tool for analyzing data and making comparisons.

**Conclusion:**
The arithmetic mean between two digits is calculated by summing up the two digits and then dividing the sum by 2 (since there are two numbers). The arithmetic mean provides a measure of the average value or central tendency of a set of numbers. It is an important statistical measure used in various fields to analyze data and make comparisons.
