Can you please explain how can we find the 50th percentile point
using this grouped frequency table? I know that it falls between
scores of 56.4 % and 34.6% which corresponds to a
score between 19.5 and 24.5. How can we find the exact 50th
percentile point? what is the easiest way to do so? Is there a
formula for that?
