This is a great resource. Thank you…thank you for making it available.
The solution to question 95 seems a lot faster and simpler than what I did, but I don’t fully get it. Can you please explain it a little further?
It is another way to calculate the mean from the sum of differences rather than the sums which can often make the calculations much easier without a calculator. There are tutorials explaining it further in the course. Good luck!
I had to post with a “Luke” commenting above. Just took the test. Thanks for putting this together whoever did it. Pretty cool.
I’m not saying it was easy or anything, but I assume the actual test is a little harder than the handbook tests?
