What criterion do we use to determine that percents
calculated from samples of one size tend to be more accurate
than percents calculated from samples of another size?
What did Dr. Thompson mean when he said, "We reach a
point of diminishing returns" when we try to increase sampling
accuracy by making sample sizes larger and larger.
The histogram below shows the simulated results of drawing
2000 samples of 500 marbles from a jar having a gazillion marbles
in it, 57% of which were red.
a) What does "285" on the horizontal axis stand
for?
b) What does "100" on the vertical axis stand for?
c) What is represented by the highlighted slice of the bar
above 300-305?
