Question on percentile computing using weighted average
Posted:
Oct 9, 2008 10:59 AM


How do I go about calculating percentiles using only weighted average numbers? For example, I need to calculate the 75th percentile but I was only given two weighted average salary data points submitted by two companies:
Company A: $46.50 weighted average hourly rate for 20 employees
Company B: $79.13 weighted average hourly rate for 30 employees
Without the individual data points for these 50 employees, how do I compute the 75th percentile correctly?
