 Statistics Power Point Presentation – Please have an in-depth background in Statistics

Introduction

You have learned lots about doing statistical analyses. It is time to work without a net.

For the course project, you will address some questions that interest you with the statistical methodology learned in this course. You choose the question; you decide how to collect data; you do the analyses. Please select a topic that aligns with your degree, so that the knowledge that you gain is practical and helpful in your future career. The questions can address almost any topic (although I have veto power), including topics in psychology, sociology, natural science, medicine, public policy, sports, law, etc. Please see the project ideas in the course documents, if you need help. However, the data that you collect should be quantitative in nature.

The project requires you to synthesize all the material from the course. Hence, it is one of the best ways to solidify your understanding of statistical methods. Plus, you get answers to issues that pique your intellectual curiosity.

Activity Instructions
Create a PowerPoint presentation detailing your research.

• Begin with very clear and well-defined hypotheses. You should think of questions that interest you first, and then worry about how to collect and analyze data to address those questions. Generally, vague topics lead to uninteresting projects.
• The most important aspects of any statistical analysis are stating questions and collecting data. Hence, to get the full experience of running your own study, the project requires you to analyze data that you collect. It is not permissible to use data sets that have been put together by others. You are permitted to collect data off the web; however, you must be the one who decides on the analyses and who puts the data set together. Keep in mind that by the end of lectures, you will have learned many inferential statistical techniques, such as hypothesis testing with t, chi square tests for goodness of fit and independence, independent and dependent t tests, ANOVA, correlation, and regression. These techniques will help you address your question of interest.
• Provide an adequate description of the methods and design of the study. Report on the possible biases associated with your data collection.
• Be realistic in planning your research design: can you carry out what you have planned within a reasonable time period and investment of your own energy? The quality of the final product is what counts, not just the amount of perspiration that went into it!
• Make use of the concepts and methods learned in this course, and not just general knowledge, in planning and completing this type of project.

Presentation Format
An effective presentation communicates your project in a clear and concise fashion. The slides should address the following six points:

• Statement of the problem: Describe the questions you address and any key issues surrounding the questions.
• Data collection: Explain how you collected the data. Include the sample type, sample size, and any questions you asked. Also, include response rates.
• Analyses: Describe which inferential statistical test analysis that you did. Be ready to explain why you believe this method is justified.
• Results: Present the six step hypothesis test. Include the EXCEL printout, and any tables or graphs that support your analyses (be judicious here–too many tables and graphs hurt the clarity of your message).
• Conclusions: State your p-value and then the answer your question of interest, based upon the data that you collected.
• Discussion: What implications do your results have for the population you sampled from? What could be done to improve the study if it was done again? What types of biases might exist?

Presentation Requirements

• Length varies
• Title slide
• References slide

 EX19_AC_COMP_GRADER_CAP_AS – Student Loans 1.0

Project Description:

In this project, you will add fields to a table and set data validation rules. You will also import a text file into a database, design advanced queries, and create a navigation form. Additionally, you will use SQL to modify a record source and create an embedded macro to automate opening a report.

Start Access. Open the file named Exp19_Access_AppCapstone_CompAssessment_Student Loans.accdb. Grader has automatically added your last name to the   beginning of the filename. Save the file to the location where you are   storing your files.

You   will import a text file into the database so that you do not have to create   it from scratch.
 

  Create a table in the database by importing the downloaded tab-delimited text   file named Loans_Text.txt. Use the   first row of the file as field names, use ClientID as the primary key, and   then name the table Loans_Text.   Accept all other default options. Do not save the import steps.

Create   a new field in the Colleges table after Phone named Website with the Hyperlink data type. Save the table. In Datasheet view, add the   website www.atlantic.edu to the Atlantic Cape Community College record (Record 1). Close the   table.

Create   a new field in the Clients table after CollegeID named StudentPhoto with the Attachment data type. Save the table. In Datasheet view for   Record 1 (Rabiah Hussein), add the   downloaded picture file named RHussein.jpg   to the StudentPhoto field.

You   will set a rule that will prevent inaccurate data entry in the table.
 

  Set the validation rule on the ExpectedGraduation field to accept the values 2021 or 2022 or 2023 (in that order) only. Set the   validation text to read Please enter 2021,   2022, or 2023. (include the period).

Make   ClientID a lookup field in the   Clients table. Set the lookup to get values from the ClientID field in the Loans_Text   table. Accept all other defaults and save the table. In Datasheet view,   click in any ClientID cell, and click the arrow to view the options. Close the   table.

You   will copy a query and use it as the basis for a new query.
 

  Create a copy of the 2022 Graduates   query. Save the query as Missing Phone.

Set   the criteria in the Phone field to find null values. Delete the criteria of 2022 from the ExpectedGraduation   field. Run the query (two records will display). Save and close the query.

Create   a new query using Design view. From the Clients table, add the ZIP field. Change the query type to Update and set the criteria to update   zip codes of 07003   to 07003-9999. Run the query (two records will   update). Save the query as Zip Code_Update   and close the query. Use the Find command to view the updates in the Clients   table and close the table.

Create   a new query using Design view. From the Clients table, add the FirstName, then LastName fields. From the Loans_Text table, add LoanAmount. Save the query as Large Loans_Make Table.

You   will modify the query so that when run, a new table is created in the   database.
 

  Change the query type to Make Table   and set the criteria to loan amounts that are greater than 25000. Run the query (fours records will be   added). Set the new table name to Large Loans.   Save and close the query. View the changes in the Large Loans table and close the table.

Create   a copy of the 2022 Graduates   query. Save the query as Graduates_Parameter.

You   will modify the query to prompt the user for input.
 

  Set the criteria in the ExpectedGraduation field to display the prompt as Enter the graduation year: and run the query. In the prompt,   enter 2022 and click OK to view the results (16 records). Save and close the query.

Create   a Navigation form based on the Vertical Tabs, Left template. Drag and drop   the Client Information form onto   the first tab of the form. Drop the Clients   Report by Year onto the second tab. View the form in Form view, click   each of the tabs, and then save the form as Navigator.   Close the form.

You will use an SQL statement to   display specific records in a report.
 

  Open the Clients Report by Year report   in Design view. Modify the record source of the report using an SQL statement   to select only client records with an ExpectedGraduation   of 2022. (Hint:   copy and modify the existing SQL code). Print Preview the report (sixteen   records will display). Save and close the report.

You   will add a button to a form that will open a report when clicked.
 

  Open the Client Information form   in Design view, and click to add a command button at the intersection of the   6-inch mark on the horizontal ruler and the 3-inch mark on the vertical ruler.

Set   the command button to open the report named Clients Report by Year. Use the default picture as the button.   Set the name and the caption properties of the button to Open Client Report. Save the form. View the form in Form   view, scroll down if necessary, and click the command button.

Close   all database objects. Close the database and then exit Access. Submit the   database as directed.

Article: (2016). Empowering Leadership and Effective Collaboration in Geographically Dispersed Teams. Personnel Psychology, 69(1), 159–198. https://doi.org/10.1111/peps.12108

There are TWO tasks that you would need to do( they are separate): 

Task 1 (Minimum 250 words): 

-Stanford University medical researchers conducted a study on the correlation between the use of fertility drugs and ovarian cancer.  Their study, published in the American Journal of Epidemiology, concludes that the use of the fertility drugs, Pergonal and Serophene, may increase the risk of ovarian cancer by three times.  The lead author of the studies, Professor Alice Whittemore, stated, “Our finding in regard to fertility drugs is by no means certain.  It is based on very small numbers and is really very tenuous.”

​FDA Commissioner David Kessler would like the infertility drug manufacturers to disclose the study findings and offer a warning on the drug packages.  He notes, “Even though the epidemiology study is still preliminary, women have a right to know what is known.  We’re not looking to make more of this than there is.”

​If you were a manufacturer of one of the drugs, would you voluntarily disclose the study information?

– Minimum two references. 

TASK 2:

Write a reply to the two responses in the attached document ( Response 1 and Response 2) with 150 words for each. 

There should be no plagiarism. Attach a plagiarism report with 0 % similarity index

Review the 2 links above.

Respond with an example of your choice that illustrates the 3Es of visualization (effective, ethical, and efficient) as outlined in the materials. Include the graphic in your response.

Explain the reasons for your choice. Also discuss other options you discarded. Your original analysis must be substantive and represent at least 50% of your response.

Note:  Please perform your own research and refrain from copying visualizations from sites where the author has already chosen a visualization and discussed it from this perspective.

i need help to get case analysis and question’s answers from the case. documents attached 

Address the questions below in a 250- to 500-word document so they can be included in the IT project proposal.

1. Explain what makes an eXtensible markup language (XML) document different from a regular text file.

1. Discuss factors that should be considered when deciding whether it is worth indexing an XML column in a SQL Server database.

1. Discuss the pros and cons of storing XML data in a SQL Server database rather than storing the XML as documents in a file system.

1. Model a real-life object as a Java class with at least one attribute and an instance method. Write a main method to create an instance of the class, assign a value to the attribute, call your method, and demonstrate that the value of the attribute changed and that the method successfully completed what it was supposed to do. The main method can be created in a separate driver class (e.g. MyDriver.java) within which you will create an instance of the object class. For example, if the name of the object class is Car (meaning, you are coding Car.java) then you can create an instance of Car inside MyDriver.java.

Be sure to create a program different from any of the programs already posted by your classmates or the examples in-class materials.

2. Reply to another student’s post. Modify the student’s class to add another attribute and a method that fits (is consistent with) the object the class is modeling, or suggest a different version of the code. Write the main method to demonstrate the correct functionality of the additions. As you reply to the other students, try to reply to a post that does not have a reply yet, and if not; try to reply to a post with a fewer number of replies.

Be sure to create a program different from any of the programs already posted by your classmates or the examples in the class materials.

As you answer these questions, use proper Java naming convention (Camel case), name the class, attribute, and method in a meaningful way to represent the business meaning, and add comments to the Java code as applicable.

The deliverables are the Java code and the documentation. The documentation is a single Microsoft Word document, or PDF containing the screenshot of the results obtained by running the code.
