Lab 03-Question 2

[maclovianunez]

When solving Question 2 for Lab 03, do I use the formula given?

Yes, some sample code is provided to help with the questions.

You will eventually need to produce your own code, but for CPP 523 the emphasis is on understanding and interpreting results. So you will have sample code to work from and adapt, and you are not being graded on your R code in this class.

So questions about proper syntax are welcome.

Dr. @lecy ,

for the same question 2 and even 3, when answering 'what happened to the strength of the relationship', exactly which variables' relationships do we need to talk about?

I thought we need to talk about the relationship between class size and test scores for both questions. If that is the case, then I would think that csize is the policy variable (PV) and test is the dependent variable, in which case, I'm not sure what the values of b_0, b_1, and tqual would be. I assumed that I can only answer this question after I plug in the values. Am I doing something wrong?

Thank you in advance,
Archana
