Here’s a fun game! Grab a piece of paper and answer these 20 questions as a range with 95% confidence interval.
The questions are crazy out there and will require guessing on most. BUT, again, you’ve gotta guess so that you’re 95% confident that the answer is within your defined range. That means when you’re done you should have exactly 19 of 20 correct.
So if the question was something like:
How many states are there in the United States?
*Note: Pretend you don’t already know the answer.
You’d have to put a range as your answer. so let’s say you said…
This means you’re 95% confident there are no fewer than 12 states, and no more than 60.
When it comes time to score, and you see the answer 50… good job! you got that question right! Don’t worry: the answers will be much more ridiculously difficult.
Once you take the test, post your actual % correct confidence interval in the comments.
