What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is calculated by dividing a value by a base value and multiplying by 100. For example, if you have a score of 80 out of 100, the percentage would be (80 / 100) * 100 = 80%.
What is Average?
Average is a statistical measure that represents the central tendency of a set of values. It is calculated by summing up all the values and dividing the sum by the total number of values. For example, if you have three exam scores of 80, 90, and 70, the average would be (80 + 90 + 70) / 3 = 80.
Formula for Calculating Average Percentage
The formula for calculating average percentage is:
| Formula | Description |
|---|---|
| Average Percentage = (Sum of Percentages) / (Total Number of Values) | This formula calculates the average percentage by summing up all the percentages and dividing the sum by the total number of values. |
