Thats what I had penciled out. I think the simplified answer from Schweser (below) sort of clouded my thought process for a moment and I disregarded the role of (n+1).
“With 20 datapoints, the top quartile (1/4) is the top 5. Count down from the greatest value to find the 5th from the top.”
Thanks. |
