Lab 04: Revenue vs Profit Preamble: 4th Sentence Inconsistent Phrasing (Moderate) #9

Closed asheynis closed 1 year ago

asheynis commented 1 year ago

In Lab 04, for the preamble to the code block for producing the Revenue vs Profit scatter plot, the 4th sentence currently reads as "Since profit generally comes from revenue, it would be custom to put profit on the horizontal axis." By the phrasing, we are to understand that profit is the "output" depending on the "input" of revenue, so in that sense revenue is the "independent variable" and should be associated with the horizontal axis as the scatter plot itself actually displays.

Aside: I also thought that I think the word "custom" should be changed to "customary", but after reading up on the words, the former is a noun which is how it is used in the sentence as given, whereas the latter is an adjective in which case the second half of the sentence quoted would need to read as "..., the customary horizontal axis should be revenue." Just thought it would be a fun often misused/misunderstood factoid to share since we all tend to abuse language based on repetition of bad usage.

Thank you for reporting that inconsistency @asheynis!

You're very welcome. I figured that might either confuse or mislead some students and was of more importance than the minor typos.
