Introduction to Mean
When it comes to Mathematics, one of the most fundamental concepts is the mean. The mean, also known as the average, is a measure of central tendency that represents the sum of a set of numbers divided by the count of numbers in the set.
Calculation of Mean
The formula for calculating the mean of a set of numbers is: Mean = (Sum of all numbers) / (Count of numbers).
Example:
Consider the set of numbers: 2, 4, 6, 8, and 10. The mean of this set is calculated as (2+4+6+8+10) / 5 = 6.
Importance of Mean
The mean is essential in various fields such as statistics, economics, and science as it provides a single value that summarizes the data set.
Case Study:
In a study conducted to analyze the salaries of employees in a company, the mean salary was found to be $50,000. This information helped the management make decisions regarding salary adjustments and budget planning.
Statistics on Mean
- In a survey of 100 students, the mean score in Math was 75 out of 100.
- The mean height of a sample of 50 adults was found to be 5 feet 8 inches.
