You will find Video 4: Variation 1: Introduction and Quartiles by navigating to the MSL Tools for Success link under Course Home. The video begins at the park, with cyclists and joggers going by. We show a very slow old woman going by on a bike, and then a bunch of racing cyclists. We point out that sometimes, what is interesting about a data set is not its average but how much it varies. We then discuss the weather in New York and San Francisco, which have pretty much the same average annual temperature, even though New York has hot summers and cold winters. Quartiles as a measure of variation are introduced by way of the price of food on take-out menus. The video ends with a practical application in medical research, where mean exposure to a toxin is far less interesting than the fact that a small number of individuals are exposed to very high levels.Answer the follow questions separately 150-200 eachWhat are some examples, other than temperature, where similar averages can be associated with very different distributions? A few thoughts: costs (e.g., cost of illegally downloading a song online is the same average cost of driving above the speed limit, assuming that you are only caught speeding occasionally); ERA of pitchers (i.e., some are very consistent, others are sometimes brilliant, sometimes horrible); success rates in surgery (i.e., do we want an operation that most surgeons can do pretty well, or one in which a few surgeons are nearly perfect and some have very poor results?)Give some practical uses of knowing variation. A few thoughts: You are traveling to a job interview; what clothes do you need to pack for a trip? Doctors need to know distributions of blood values to know whether a patient is out of range; industrial engineers need to know distributions, for example the strength of a certain part to see if there is a problem with a manufacturing machine; clothing manufacturers need to know the distribution of sizes, for example children’s clothes for a certain age.For many years, the New York subway had no air conditioning on the grounds that the average trip was only 15 minutes, and 15 minutes without air conditioning is no hardship, even in the New York summer. Critique this reasoning.

Create a 12- to 15-slide presentation using the information you gathered and submitted in Weeks 3 and 4. Include the following:undefinedDescribe the problem and provide some brief background information about the situation.Explain the research hypothesis.Describe your sample and your sampling method.Explain the four steps of the research process you followed, and define the critical value and the test statistic your analysis provided.Provide the main finding of the study. What did you prove or fail to prove?Provide recommendations based on your findings.undefinedFormat any citations in your presentation according to APA guidelines.Expectations for PowerPoint PresentationsEnsure you develop your presentations with the proper number of slides suggested under the assignment and meet the learning objectives for the presentation as well. You are required to include at least 3 credible research sources, one of which MUST be the textbook, for presentations. Sources and graphics need to be properly cited and referenced in APA 7th edition style. You need to include in-text citations on each of your individual slides in addition to completing reference slides at the end of the presentation. Keep in mind your title slide should include your presentation title, your name, and the date of submission. Slides should have no more than 7 words a line and 7 lines per slide (7x7 rule), using short phrases and simple sentences. Provide only key points on your slides – use your speaker notes for more detailed information. Limit the information on your slides to essentials. Font size on your slides should be between 24-48 points in easy-to-read fonts like Arial, Courier or Times New Roman. If you need multiple slides for your references, this is fine but realize these do not count toward your total slide count for your content. Avoid using ALL CAPS and use the same font style for your entire presentation. Avoid using font colors that are difficult to read – avoid the color red in particular. For a professional look on your slides, use two spaces between all words. Remember to avoid using abbreviations and acronyms on your slides. Graphics and special effects are wonderful but keep in mind not to overload your slides with too many graphics, too much text, or too many effects. The general rule is no more than 2 graphics per slide. However, you should not have a presentation that lacks graphics completely. Also, please ensure you cite/reference your images appropriately in APA style. Ensure you include your Part II Excel output for your t-test on one slide and also explain the corresponding results of this test in the presenter notes.Speaker/presenter notes are required for every slide in the presentation. Presenter notes are where you include your specific information that explains the information on your slides. Your presenter notes should be written using complete sentences (no outlines). Your notes should be where you explain your slides and provide your audience with more information about your topic. Think of your notes as what you would be saying if you were to give this presentation in person to a room full of people. As such, the information should flow and should be clear and free of errors. Your presenter notes and your slides should be proofread and spell-checked. Please ensure your work is original. I do check for plagiarism.

Have you ever worked in a management or leadership position and experienced situations in which employees were not meeting your performance expectations? Or, perhaps you worked under a manager who continually blamed problems of production, output, or sales on you and your colleagues. An important takeaway from the red bead experiment is to consider instances such as these and question whether the fault lies with the employees or with something else, such as management’s decisions or the system that is put in place. As you discuss the red bead experiment, consider how you might be able to relate the lessons learned to your own experiences.In this Discussion, you will examine the red bead experiment and discuss the success of its implementation, as well as how the concepts derived from it can be applied to other aspects of the workplace.To prepare for this Discussion:Review this week’s Learning Resources, focusing in particular on the resources on the Red Bead experiment in the Analyzing Process Variation Using SPC section. Be sure to review The Red Bead Experiment media piece and the Red Bead Experiment Control Chart document.Review the Academic Writing Expectations for 2000/3000-Level Courses, provided in this week’s Learning Resources.By Day 3Post a 225- to 300-word (3- to 4-paragraph) explanation of how successful the Red Bead experiment was and how an example of the experiment in the workplace can be fixed. In your explanation, address the following:Explain your thoughts on the working climate at the White Bead Company. Describe what the advantages and disadvantages of the inspection system are. Were the strategies that management tried successful in improving workers’ performance? Explain why or why not. Provide an example of a situation similar to the Red Bead experiment that you have experienced in the workplace or have heard someone else describe. Explain how you might improve it. To support your response, be sure to reference at least one properly cited scholarly source.
