The Definition of Mean
Mean, often referred to as average, is a mathematical concept used to quantify data by finding the sum of a set of values and dividing it by the number of values in the set. It provides a central point around which the data is distributed, making it a useful measure for understanding the characteristics of a dataset.
Examples of Mean
For example, if a class has 5 students with scores of 80, 85, 90, 95, and 100, the mean score of the class would be (80+85+90+95+100)/5 = 90. This indicates the average performance of the students in the class.
Case Studies on Mean
In a study conducted on customer feedback ratings for a product, the mean rating was found to be 4.2 out of 5. This provided valuable insight into the overall satisfaction level of customers with the product.
Statistics on Mean
According to a survey on income levels in a city, the mean income was calculated to be $50,000. This helped in analyzing the economic status of the residents in the area and making informed decisions based on the findings.
