Mathematical Explanation
\n
To find the percentage of the mean, we use the following formula:
\n
Percentage = (Value / Mean) * 100
\n
When standard deviation is considered, the interpretation changes to understand how far the value is from the mean in terms of standard deviations.

Practical Example
\n
Let’s say we have the following values:
\n
- \n
- Value (X): 65
- Mean (μ): 50
- Standard Deviation (σ): 10
\n
\n
\n
\n
Calculation:
\n
Percentage = (65 / 50) * 100 = 130%
\n
This means the value 65 is 130% of the mean 50.

Key Factors That Affect Results
\n
- \n
- Value (X): A higher value will result in a higher percentage.
- Mean (μ): A lower mean will result in a higher percentage, assuming the value remains constant.
- Standard Deviation (σ): While not directly used in the percentage calculation, it provides context for the interpretation.
