Using the following data (which are sample scores), construct a
Grouped Frequency Distribution on your scrap paper.

What score is associated with the 50th percentile?

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?

z-Score Using the database created in W1 Assignment, convert
each subject's age and height into a z-score. Using the z-score of
±1.645 for the 5 percent cutoff and the z-score of ±1.96 for the
2.5 percent in the tail, identify the subject identification (ID)
number for subjects who are closest to the cutoff for the upper 2.5
percent and 5 percent of the scores and the lower 2.5 percent and 5
percent of the scores. Do this by comparing each...
