Hello Everyone!
I am working through Lab 4.1.3 APPLIED LAB in the DataX class and I am uncertain as to the answer to Question (2) below and justification for the answer. I repeatedly get it wrong and I keep having to restart the Lab VM just to get to try the get this question correct. I think I am applying sound thinking as to what the correct answer should be, but perhaps there is someone who can provide the official answer and why it's the official answer?
(2) Which of the following columns can be calculated?
year
day
dep_delay
arr_delay
air_time
month
I am going to eventually get it right after going through all of the possible combinations but it is much appreciated if someone can help clarify why the official answer is what it is as I am misunderstanding the context of this question. I will need to explain to the students why this answer was chosen to remove any subjectivity.
I had also asked previously if there is a place where all of the DataX lab solutions and answers to all questions are posted so students can refer to them afterwards on their own time. Is there an update on this, and is there a plan to provide an answer key and/or ZIP of the completed notebooks?
Thank you!
Ben
