When taking an exam, some students quickly answer all the questions they know how to do. If they go back and revise their answer
s, they start second guessing themselves and end up changing their choice from the correct answer to an incorrect one. Other students work through the exam very slowly - they think things very thoroughly, revise their answers several times, and carefully make sure they have not missed anything. In a class where we have both these types of students together, the correlation between the amount of time spent on an exam and their grade should be: _____________ a. Positive and fairly strong
b. Negative and fairly strong
c. Fairly weak
We can deduce that the correlation between those two criteria is fairly weak. This is because the first set of students who initially answered the question started second-guessing themselves, making them unsure about their decision when picking the right answers. They eventually ended up choosing the wrong answers when changing it.
Do you have paper and a pen on you this is very simple to workout The first one is 4 and the other one is 3587.5 and the last one is <span>8.0992869</span>
It wouldn't be exponential because there isn't exponent, and it won't be rational because there is no fraction, and it is not quadratic. Hope this helps :)
