The coefficient of variation is the square of the correlation coefficient, and it measures what % of variations in one variable can be explained by variations in the other variable.
I do explain this in my free lectures – did you watch the lectures before attempting the test?
In question 3, there is no mention of Coefficient determination but why the explanation includes determination?
Please can someone advise?
how did you get 11 as n (from question #1)?
Hello John,
Can I just say that this topic was explain really well. Thank you
Thank you for your comment 馃檪
Good day madam/sir
Can you please explain me question #3?

Question #5 for the high low method, the highest level is 75000 not 74000. If 74000 is being used, can you kindly explain why.
thank you.
We use the highest and lowest of the independent variable which here is the production units. I do explain this in my free lecture.
Good Day Sir,
can you kindly elaborate a little more on question #2.
But what do you want me to elaborate? As the answer says, the coefficient must lie between +1 and -1 (which 1.4 does not).
Again, I explain this in my free lectures – did you not watch the lectures before attempting the test?
