Question

Air Travel Industry
You are a researcher for a professional research
firm. Your firm has won a contract to do a study for
an air travel industry publication. The editors of the
publication would like to know their readers’
thoughts on air travel factors such as ticket
purchase, services, safety, comfort, economic
growth, and security. They would also like to know
the thoughts of adults who use air travel for
business as well as for recreation.
The editors have given you their readership
database and 20 questions they would like to ask
(two sample questions from a previous study are
given at the right). You know that it is too expensive
to contact all of the readers, so you need to
determine a way to contact a representative sample
of the entire readership population.

How They Did It
When the Resource Systems Group did a similar study, they used an Internet survey.
They sent out 1000 invitations to participate in the survey and received 621 completed
surveys.
(a) Describe some possible errors in collecting data by Internet surveys?
(b) Compare your method for collecting data in Question 1 to this method?

Answer 1

Question 1 is not given so part B cant be solved. Please post method used in question. I am answering part A.

A. There are some problems that a survey dollection such as this can produce. These are-

• Not necessarily representative og the readers- The survey population was not chosen to represent accurately the demographics of the readers of the magazine. Even worse, only 621 out of the 1000 replies. Thist must have distorted the data further- showing that not all readers of the magazine might have internet and they are being left out of the survey.
• No oversight- Since no one is overseeing the answers being given, many people might just enter random or dummy values, thus creating noise in the data.
• No one to probe in- No one can probe the answers further as there is no one with the people when they are answering the questions. This makes it tough to get to the correct issues.
