Case Study Analysis Assignment:

Task: Scenario 1 A health-food company is planning to market a new one-month weight-loss “diet-shake” program to the public.  The company executives believe the program will be effective in helping people lose weight, however they require scientific evidence of its success to use in a future advertising campaign. To help them gather this evidence, you randomly recruit a group of 40 volunteer participants from the public who have been identified by medical professionals as clinically “obese” and measure their weight.  You then immediately administer the diet program, which consists of a three “diet-shakes” and three very small meals a day,  and a specialised exercise regime.  Every participant starts on the same day, Monday of Week 1, and ends the program on the same day, Friday of Week 4.  Throughout the month you monitor your participants and are please to find they are all taking the program seriously. At the end of the one-month program you organise for your participants to take a second weight measurement, however many of the participants are taking summer holidays and are not available for you to weigh.  Consequently, you decide to postpone the second weight measurement and wait an additional two months before re-weighing them (so that all 40 can participate). Finally, three months after the beginning of the program you finally get your chance and collect new weight measurements from the 40 participants.   You use the data from these participants to answer the company’s question – did the program result in a significant drop in weight? TASK 1 Analyse the data and write a results section using APA format.  TASK 2 Describe the research findings using a single sentence (i.e., write a clear statement explaining whether the company’s hypothesis was supported or not supported.). TASK 3 There is a hidden design flaw in this scenario.  Identify this flaw and explain how it might affect your statistical finding, hence lead to an inaccurate conclusion. Scenario2 A large privateITorganisation is interesting in determining theintelligence oftheir 1000employees, and asks you to compare the IQ (intelligence quotient) of a sample of employees with the population IQ score of 100. The company’s management team assumes their employees will be more intelligent than the population. Using the organisation’s emailsystem, you email everyone in the company requesting volunteers to take part in an intelligence study.  In reply you receive expressions of interest from 20 enthusiastic employees.  These 20 employees agree to complete a validated IQ test at the organisation’s head office on a Friday morning.  The data you collect from them is shown in Table 1. TASK 1 Analyse the data and write a results section using APA format.   TASK 2 Describe the research findings using a single sentence (i.e., write a clear statement explaining whether the company’s hypothesis was supported or not supported.).   TASK 3 There is a hidden design flaw in this scenario.  Identify this flaw and explain how it might affect your statistical finding, hence lead to an inaccurate conclusion.
