Straighterline Business Statistics - Need Advice

Is anyone familiar with what the last quiz (not the final) is like content wise? Do they provide the values and expect me to construct the regression equation, make inferences, etc, or will I be plugging data into excel to get the needed variables? I’d like to get at least an 80% on this quiz so I only need a 40% on the final to pass the course. I’m a bit nervios since this one appears to be based almost exclusively on using excel to do the heavy lifting of getting the details from the data, at least from the content in the book, and I am used to making most of the calculations myself with an nspire.

Any advice is appreciated.

 

Well, answering my own question for anyone who searches in the future. Quiz six is almost entirely theory, with a number of questions based on degrees of freedom of presented data, critical values, etc. not terribly difficult.

 

I have never taken a Straigherline course so I don't know if I'm correct when I say that it would be very easy to have a random number generator choose some small number of quiz questions from a larger pool of questions. The result would be no individual takes the exact same test. It's such an easy partial solution to the cheating problem that I'd be a bit shocked if they weren't doing it.

 

I would be impressed if they actually are. They have a (short-term) financial incentive to not go too far out of their way to crack down on cheating.

 

It would be fairly hard to cheat in some of the problems. Some of them are based on randomly generated frequency distributions and associated hypothesis tests. You either know how to apply the material, or pray you roll a lucky 1 in 4 on your guess. Others were things like what would the associated critical value be for x degrees of freedom. You have to decide if it’s an F, t, or X^2 they are referring to and how many degrees of freedom the data would require.

 

Perhaps by luck of the dice roll, the final proved much easier than quizzes 5 & 6.

Much more theory based than Aleks statistics which I also did.

Done.
