Lab 02 Question Clarification #34

Open rfb-vibe opened 3 years ago

rfb-vibe commented 3 years ago

On the html lab instructions, for Q7, it says:

What proportion of commercial properties are delinquent on taxes? What proportion of delinquent tax bills are owed by commercial parcels?

On the RMD file, it says: Question I: What proportion of commercial properties are delinquent on taxes? Question II: What proportion of delinquent tax bills are owed by commercial parcels?

But then in the r code chunk, it says: The first answer is tax-delinquent commercial properties over all commercial properties The second answer is the tax dollars owed by commercial properties (a subset) over all tax dollars owed

Question: For the second question, am I trying to find the proportion of delinquent taxes owed by commercial properties, or am I trying to find the amount of tax dollars owed by commercial properties? Each iteration of the question seems to be asking something different and I am getting confused.

@rfrost811 good question and this one always trips learners up! Also, kudos for formatting your GitHub post!

Question: For the second question, am I trying to find the proportion of delinquent taxes owed by commercial properties, or am I trying to find the amount of tax dollars owed by commercial properties? Each iteration of the question seems to be asking something different and I am getting confused.

Your first interpretation is correct! Viz.

...am I trying to find the proportion of delinquent taxes owed by commercial properties...

So a good way to go about this may be to subset all tax-delinquent properties - find out the total amount delinquent for all properties, then the total amount only for commercial properties, and you can calculate a proportion that way. Does that help? Ironically, I tried to rephrase it differently for clarity!
