How to find the percentiles for certain data point? I have two data points that I need to find the percentiles for. One is data point 3 and the other one is data point 5. Data point 5 is the Q3, so it is 75 percentile.. but I don't know how to find data point 3. The 5summary is: Min = 1 Q1 = 2 Med = 3.5 Q3 = 5 Max = 6 Is there any other information I need to find the percentile for data point 3? I read the textbook but can't find relevant information on solving this problem. Please help. Thanks in advance.

With out more data the closest you can get is between 25% and 50%.
