Week 1 – U.S. Student Aid Initial Database Schema

/in /by

Resource: U.S. Government Website

You are assigned a project to evaluate higher education student aid data from the U.S. government to answer the following questions:

  • Which schools generate the highest amount of debt for the average student who attends?
  • What is the employment rate for the students who graduate from this school?

You will complete this project through weekly Individual Assignments. Each weekly assignment builds on previous assignments.

This week, you will complete an initial review of the data and prepare an initial database schema and data discrepancy recommendation.

Download the following spreadsheets or CSV files:

  • School Code List
  • Most current spreadsheets for Loan Volume, Grant Volume, and Campus-Based Volume
  • Gainful Employment Information

Develop a database schema diagram based on the data tables you downloaded in Microsoft® Visio® that includes:

  • The identification of metadata that needs to be included in each table
  • Annotation of the diagram to identify where there may be schematic discrepancies between the data sources

Summarize your recommendations for resolving anticipated discrepancies and identify which strategy you would use to validate the data quality in a Microsoft® Word document.

Note: You will use the downloaded files and your drafted schema in the Week Two Individual Assignment titled, “U.S. Student Aid Database Schema and Query Recommendations.”

I need the dat analysis portion done for a critique paper. Attached is the text book required.

Directions for the Assignment: Group Research Critique

“Students will work in small groups on this assignment. Dr. Christensen will assign students to groups of 4 or 5 members each. Each group will choose one, instructor-approved research article, to critique and will incorporate the critique criteria as outlined in the textbook (see chapter 4 – Tables 4.1 & 4.2). The article chosen may be either a quantitative research article or a qualitative research article. Do not choose mixed methods studies or systematic reviews. Each group will write a formal research critique for the article chosen. All papers will be written using APA format (6th edition). Papers must be submitted on time. Refer to the criteria/guidelines for details concerning requirements below. This paper is due on week 11.

Critique Criteria & Reference Pages: See Polit & Beck, pages 66-67 for explanation of guidelines. For each specific topic, refer to the corresponding pages in the textbook for assistance. There are two examples of critiques in the textbook on pages 357 and 389 (Qual & Quant). Make sure you address each of the major categories/headings. See grading guidelines and rubric below.”

Article to be critiqued:

Specifically my portion of the paper needs to address theses questions from ch 14 in the book:

Were appropriate statistical methods used?

was the most powerful analytical method used? did the analysis control for confounding variables?

Where type 1 and type 2 errors avoided or minimized? Due to the confidence interval of 95%, it is unlikely that the researchers made a type I or type II error.

1. Did the descriptive statistics in the report sufficiently describe the major variables and background characteristics of the sample? Were appropriate descriptive statistics used for example was a mean presented when percentages would have been more informative?

2. Were the statistical analysis undertaken to assess threats to the study’s validity for example to test the selection biased or attrition bias?

3.Did the researchers report any inferential statistics? If inferential statistics were not used should they have been used?

4.Was the information provided about the hypothesis testing and parameter estimation(confidence intervals?) Were effects sizes reported overall did the reported statistics provide readers with sufficient information about the study results.

5.Were any multivariate procedures used? If not should they have been used for example would the internal validity of the study be strengthened by statistical controlling confounding variables?

6.Were the selected statistical tests appropriate given the level of measurement of variables and the nature of the hypothesis?

7.were the results of any statistical test significant what do the test tell you about plausibility of the research hypothesis? were effects sizable?

8.were the results of any statistical tests nonsignificant? is it possible about that these reflect type 2 errors? what factors might have undermined the study’s statistical conclusion validity?

9.Was information about the reliability and validity of measures reported? Did the researchers use measures with good measurement properties?

10. Was there an appropriate amount of statistical information? Were findings clearly and logically organized? Were tables or figures used judiciously to summarize large amounts of statistical information? Are the tables clear with good titles and row/column labels?

There is a link between understanding the purpose of one’s research and selecting the appropriate methods to investigate the questions that are derived from that purpose.

–(Newman, Ridenour, Newman, & DeMarco, G. M. P., Jr., 2003, p. 169)

For this Discussion, you will evaluate the purpose statements in assigned journal articles in your discipline and consider the alignment of theory, problem, and purpose. You will also explain your position on the relationship between research and social change.

Alignment means that a research study possesses clear and logical connections among all of its various components. To achieve these connections, researchers must carefully craft the components of their study such that when they are viewed together, there is a coherent interrelationship.

As you read the authors’ purpose statements, consider how well the intent of the study, and its connection to the problem and theoretical framework, is presented. Also consider if the purpose statement reveals the study’s potential for engendering positive social change.

As you know, social change is a distinguishing feature of Walden University’s mission. Positive social change implies a transformation that results in positive outcomes. This can happen at many levels (e.g., individual, family systems, neighborhoods, organizations, nationally and globally); and positive social change can occur at different rates: slow and gradual or fast and radical.
