SUMMARY
The percentage difference is calculated using the formula
\(\frac{|x_{known} - x_{exp}|}{x_{known}} \times 100 = perc\)
. This formula allows data analysts to quantify the difference between a known value and an expected value as a percentage. It is essential for evaluating the accuracy of predictions and understanding data variability. The discussion emphasizes the importance of this calculation in data analysis for making informed decisions based on numerical comparisons.
