True
False
===================================================
8.
Question 8
Why do you think that
the internal and external analyses in the Customer Acquisition Strategy case study
were done in parallel?
They relied largely on different data and used different techniques, so they could be done independently
Doing the analyses in parallel allowed the project to be completed more rapidly
It allowed the team to avoid biases that could be introduced by doing the internal
or external analysis first
Allof these are reasonable reasons to do the analyses in parallel

Question 8
The blue dots in the following graph represent the average fare corresponding to the number of days the tickets were booked in advance. The orange line represents the overall fare average (i.e., the average fare for all flights in the dataset). The graph shows that as the departure day approaches, the airfare tends to increase. It also shows that purchasing tickets far in advance results in fares that tend to be above the overall average. There is a “sweet spot” (for the traveler!) at around 100 days where fares are below the overall average.
In video 6 of module 3 of this course, we discussed 7 principles for telling compelling stories. This graph is an example of the following principle:
1 point
The graph translates complicated airline jargon to terms that are familiar to a traveler.
The overall average airfare (represented by the orange line) provides the right context to compare how airfare changes over time as the departure day approaches.
The graph provides a seamless integration of text and pictures
The graph is misleading regarding how yield management programs work.
===================================================
9.
Question 9
Suppose the airfare data set were available to a small consulting firm with locations in Detroit (DTW) and Minneapolis (MSP). Most of their consultants travel each week from those locations to client locations that are represented by the destinations in the data set.
The firm wants to provide guidance to its consultants to try and keep travel spending as low as possible. One unique aspect of their travel booking is that they normally try to book travel 3-4 weeks in advance, but may often book less than 2 weeks in advance of travel.
Which booking channel
should they recommend in general to get the lowest fares?
1 point
Expedia
