How to calculate marks from percentiles?

To find marks from percentiles, you need the sorted data set and the percentile; calculate the rank using Rank = (Percentile / 100) * (N + 1), then if the rank is a whole number, find that score, or if it's a decimal, interpolate between the scores at the ranks around it (e.g., 8.4 means average the 8th and 9th scores, weighted by the decimal). This gives the raw score (mark) corresponding to the percentile within your specific group.
