Statistical Advisor Critical Thinking Paper I: No Worries Cruise Line

Instructions: For the scenario on the next page, write a paper that explains the following to a prospective client:

Formulate both null and alternative hypotheses for the client, and explain why the hypotheses need to be directional or non-directional.

Determine what statistical test should be used to analyze the data.

i.Summarize all information used to determine the correct statistical test (e.g., number of groups, type of data collected, independent or repeated measures)

ii.State what statistical test should be used (be specific).

iii.Provide a sample size and critical values in relation to the hypothesis (Note that you have been provided all of the needed information to determine the critical value(s)).

Discuss what the statistical analysis will do in answering the hypotheses and question(s) for the client. Also discuss any potential problems to watch out for, including an appropriate sample size to meet the assumptions of the statistical test.

Be sure to use and show critical thinking in your writing. By critical thinking, you need to demonstrate the importance of scientific processes, how science will further our knowledge, and how your scientific approach is applicable to real world knowledge.

Last, your paper should have a title page, be written in 12 point Times New Roman font, and presented in paragraph form that is professional and free of grammar and clarity problems. If you use information from a source other than your textbooks, than cite that source and provide a reference page. It is expected that most students will not need a reference page for this assignment.

Client Scenario: No Worries Cruise Line

                  No Worries Cruise Line has started receiving less customers, and they are starting to get worried as to what is happening. A corporate employee, Eddie, has been asked to look into the matter. Eddie gathered up all the contact information of everyone who went on one of their cruises for the last three years. In order to gauge differences in satisfaction, Eddie created a questionnaire, which he sent to everyone who had taken a cruise with them the last three years. He had them rate levels of happiness, relaxation, food/drink quality, and entertainment quality on scales of 1-10, with 10 being highest level. He gave anyone who completed the survey a 10.00 dollar Starbucks card. He got 3,000 responses, with 1,000 responses from each of the last three years. Eddie does not know how to statistically examine the data, so he asks you to consult him on how to examine the data. The key question that Eddie needs answered is how to determine if satisfaction levels have changed over these last few years.

No other information given.

Explanation / Answer

in this particular case

the no. of groups will be =3 because we have to find out change in statistics over time(one group for each year)

type of data = ordinal ( as the people will rate it on a scale of (1-10) and categorical = happiness, relaxation, food/drink quality, and entertainment quality

we will use independent measures to exactly find out the cause of receiving less customers.
