Explain a problem that might be solved using hypothesis testing. Would you use a one sample test or a two sample test and why? Run the problem in Megastat (using real or hypothetical data) and interpret the results.
Write an opinion piece and answer three questions.
1. In your opinion explain what Quantitative Analysis skills should be part of the curriculum obtaining a masters degree at Graduate School of Business. This is not a trick question.
2. Some people are very good at Quantitative Analysis, while other struggle with it. What are the advantages of having high level skills in this area. If you believe there are no advantages explain yourself.
3. In your specific career describe how do you anticipate you will be using Quantitative Analysis skills in Healthcare Systems.

MBAN 606: Quantitative Analysis
Overview
Here is a guide to the format.
Sections
1.0. What is the purpose of the survey? What are you attempting to discover? Hint – it is to assess the viability of a new business. Hint – it is not to play with a variety of statistical techniques to demonstrate you can perform them.
2.0. What are the main findings? How many people overall are interested? How many people in each condition are interested? How, if at all, does price influence interest? How are interested people different from people who are not interested?
3.0. What else relates to interest in the new service? Possibly nothing, possibly something. Other factors may be interesting, but they are not as important as the main measure. Correlating other factors to one another is OK, providing you have a good reason for doing it.
Guidelines
1.0. If you do calculations, show them. Be neat and organized.
2.0. Make sure you can back up any claims you make.
3.0. Assume you are writing for a stranger. This means be very clear, be succinct, get to the point, be convincing. Assume the stranger will severely criticize your work, so be careful.
Use the data in the following table that shows results from a polygraph (lie detector) conducted by researchers Charles R. Honts and Gordon H. Barland. In each case, it was known if the subjects lied or did not lie, so the table indicates when the polygraph was correct.
| Did the subject actually lie? | ||
| No (did not lie) | Yes (did lie) | |
| The polygraph test indicated that the subject lied. | 15 | 42 |
| The polygraph test indicated that the subject did not lie. | 32 | 9 |
Present and discuss two ways of structuring the presentation of collected data from questionnaires. Describe for each one how the collected data are analyzed. “slides are attached”
Lab Report Guide for a Virtual Organism
You will be writing a scientific paper which is unlike any history, English or philosophy paper. Your report should be written in prose and should follow APA format. Please pay attention to grammar, spelling and correctly writing the name of your organism. Plagiarized reports will result in an automatic F so write in your own words! The report should be 10 paragraphs (about 3-5 pages) long.
The paper is to be divided into sections. Each section must have its own heading. The Headings are:
1. Title: Choose something descriptive, for example: Identification and analysis of Bacillus cereus
2. Introduction: 1-2 paragraphs
a. Assume you are a consultant to a medical laboratory. The lab tech calls you and says, “I have been given an unknown sample. What do I do?”
b. Background information – A little information about what you tell the lab tech and why.
c. Purpose objective – what was the purpose of your advice?
3. Materials and methods: 1-2 paragraphs
a. Written in prose (not as a list) include what should be used in order and how it would be done. Use the flow charts as a guide for which test would be done in which order. In your conversation with the lab tech, if there is a choice for direction of the flow chart (for example: Streptococcus versus Staphylococcus) describe WHY you went the direction you did. DO NOT INCLUDE RESULTS.
b. This should be written so anyone could reproduce your procedure. Do NOT include unnecessary information such as ‘walk to the sink’. Remember that all this information is in a lab manual so if you can refer to that manual, do so without describing each step.
4. Results: 1-2 paragraphs AND a table/graph or figure (pictures are acceptable).
a. This is for all the tests that were done
b. Include a table, flow chart, or figures of depicting your results (both positive and negative)
c. Include text describing your results and the final outcome
5. Discussion or conclusions: 2-3 paragraphs
a. Analyze your data (explain what your results mean- did you confirm the correct organism?)
b. Based on your knowledge as a consultant, describe any other experiment or procedure that you found that we did not cover in class that would be helpful in identifying the unknown. (what would you do differently next time, etc.)
c. Discuss CLINICAL SIGNIFICANCE OF YOUR UNKNOWN! You will need to do some research and include this in your report with references to those cited in the next section (Dolan, and Vuilleumier, 2003; Eastwood, et al., 2001).
i. Include the diseases/infections it causes
ii. Route of transmission
iii. Treatment and prevention
6. References
a. You need at least 3 references. One may be a lab manual.
b. Properly cited: use the APA format for referencing (including in the text). Examples of APA citations: (for more information visit for a tutorial)

The aim of the assessment is to produce a critical evaluation of the processes of talent identification considering theoretical models and real world applied applications.
Main objective: To demonstrate ability to maintain a linked set of statistical investigations into what is really going on in the data, and to find/discover/invent fresh questions to be asked of it.
Predict success in graduate school with regression.
Go to Canvas and download SuccessInGradSchool.pdf. ETS (Educational Testing Service) Owns the GRE (Graduate Record Exam). In 2005 they performed a large study to predict success in graduate school. They used a multiple regression model with three factors Undergraduate Grade Point Average (U), GRE Verbal score (V), GRE Quantitative score. Note that they have a vested interest in proving the GRE scores have merit. The investigators are professionals from an elite institution with a sizable research budget.
Go to page 23 in their report “Table 3 Predicting Cumulative Graduate Grade Point Average.” They report the multiple R score for each of five different majors. Furthermore, they believe that the multiple R scores are underestimates, so they show “corrected multiple R” scores. Examine these key findings, and comment on the success of their multiple regression equations. Explain your reasoning.

ASSESSMENT 2: Data Analysis Assignment
You have been provided with the data for this assignment as an SPSS file. The data file has been provided with generic variable names (V1, V2, etc.), which you should change. You will need to provide more detailed VARIABLE LABELS and VALUE LABELS in the data file.
The hypothetical study examines the relationship between body mass index (BMI), sex, and different measures of response inhibition, delay of gratification, and positive/negative affect. The researchers recruited 120 adults and recorded their sex (V1: 1 = female; 2 = male) and BMI (V2: 1 = underweight; 2 = normal; 3 = overweight). Participants reported their level of hunger (V3) – at the start of the study – on a Likert scale ranging from 1 = “not hungry at all” to 9 = “extremely hungry”.
Participants then completed a range of self-report measures:
Finally, participants completed a Go/No-Go task, which measures inhibitory control. A Go/No-Go task presents two stimuli; one is a “go” target to which participants are instructed to respond as fast as they can (e.g., by pressing spacebar on a keyboard), and the other is a “no-go” target to which one must withhold responses. Failure to withhold responses to no-go targets is known as a commission error. The lower the commission error, the better is the inhibitory control. The current study used happy and sad faces as the stimuli. In the first half of the task, happy faces were the go and sad faces were the no-go targets. In the second half, the sad faces became the go while the happy faces were the no-go targets. Previous literature suggests those with reduced inhibitory control find it more difficult to resist responding to happy than sad faces. V6 represents commission errors to happy no-go targets, and V7 commission errors to sad no-go targets.
Your first task is to provide appropriate variable labels for all the variables and value labels for V1 (sex) and V2 (BMI). After this, answer the following questions. You must provide the relevant SPSS output along with any write-up that is requested. Any figures or tables must be in APA style. You are not required to interpret any of the results in “common sense” terms. The exercise is solely related to the data analysis, and the variables and their scores are somewhat arbitrary, so don’t worry if the results don’t make “real world” sense. This is not real data, so don’t worry if the results seem odd.
There are two parts to this report. The most important part consists of the write up of the analyses, including graphs and tables (if required) in correct APA style; in other words, in the style that you would use if you were presenting this material in a research report. The second part consists of the raw SPSS output of the analysis that you have carried out. Both sections need to be combined into a single Word file for submission to the online class space. Remember that SPSS provides a lot of output. Not all of this output needs to be submitted with your assignment. You should copy and paste only part of the output that directly relates to the question that you are answering.
Please note that you are required to answer ALL SIX questions. Each question worth 5 marks.
