Descriptive Statistics

Descriptive Statistics

This week, you explore key statistical concepts related to data and problem solving through the completion of the following exercises using SPSS and the information found in your Statistics and Data Analysis for Nursing Research textbook. The focus of this assignment is to become familiar with the SPSS data analysis software and to develop an understanding of how to calculate descriptive statistics and make conclusions based on those calculations. As you formulate your responses, keep in mind that descriptive statistics only allow you to make conclusions and recommendations for the sample at hand—not for the larger population to which that sample may belong.
To prepare:

• Review      the Statistics and Data Analysis for Nursing Research chapters      assigned in this week’s Learning Resources. Pay close attention to the      examples presented, as they provide information that will be useful when      you complete the software exercise this week. You may also wish to review      the Research Methods for Evidence-Based Practice video      resources to familiarize yourself with the software.
• Refer      to the Week      4 Descriptive Statistics Assignment page and follow      the directions to calculate descriptive statistics for the data provided      using SPSS software. If you run into any difficulties or problems, post      them to the Week 4 Discussion 2 area (see attached file)
• Download      and save the Polit2SetA.sav (see      attached file) data set. You will open the data file in SPSS.
• Compare      your data output against the tables presented in the Week 4 Descriptive Statistics SPSS Output      document (see attached file) This will enable you to become      comfortable with defining variables, entering data, and creating tables      and graphs.
• Formulate      an initial interpretation of the meaning or implication of your      calculations.

To complete:

• Complete      the Part I, Part II, and Part III steps and Assignment as outlined in      the Week      4 Descriptive Statistics Assignment page. (see      attached file for week 4 descriptive statistics assignment page)

ADDITIONAL INSTRUCTIONS FOR THE CLASS

SCORE A+ WITH HELP FROM OUR PROFESSIONAL WRITERS: ORDER NOW FOR AN ORIGINAL PAPER ASSIGNMENT

We will process your orders through multiple stages and checks to ensure that what we are delivering to you, in the end, is something that is precise as you envisioned it. All of our essay writing service products are 100% original, ensuring that there is no plagiarism in them. The sources are well-researched and cited so it is interesting. Our goal is to help as many students as possible with their assignments, i.e. our prices are affordable and services premium.

• Discussion Questions (DQ)

Initial responses to the DQ should address all components of the questions asked, including a minimum of one scholarly source, and be at least 250 words. Successful responses are substantive (i.e., add something new to the discussion, engage others in the discussion, well-developed idea) and include at least one scholarly source. One or two-sentence responses, simple statements of agreement or “good post,” and responses that are off-topic will not count as substantive. Substantive responses should be at least 150 words. I encourage you to incorporate the readings from the week (as applicable) into your responses.

• Weekly Participation

Your initial responses to the mandatory DQ do not count toward participation and are graded separately. In addition to the DQ responses, you must post at least one reply to peers (or me) on three separate days, for a total of three replies. Participation posts do not require a scholarly source/citation (unless you cite someone else’s work). Part of your weekly participation includes viewing the weekly announcement and attesting to watching it in the comments. These announcements are made to ensure you understand everything that is due during the week.

• APA Format and Writing Quality

Familiarize yourself with the APA format and practice using it correctly. It is used for most writing assignments for your degree. Visit the Writing Center in the Student Success Center, under the Resources tab in Loud-cloud for APA paper templates, citation examples, tips, etc. Points will be deducted for poor use of APA format or absence of APA format (if required). Cite all sources of information! When in doubt, cite the source. Paraphrasing also requires a citation. I highly recommend using the APA Publication Manual, 6th edition.

• Use of Direct Quotes

I discourage over-utilization of direct quotes in DQs and assignments at the Master’s level and deduct points accordingly. As Masters’ level students, it is important that you be able to critically analyze and interpret information from journal articles and other resources. Simply restating someone else’s words does not demonstrate an understanding of the content or critical analysis of the content. It is best to paraphrase content and cite your source.

• LopesWrite Policy

For assignments that need to be submitted to Lopes Write, please be sure you have received your report and Similarity Index (SI) percentage BEFORE you do a “final submit” to me. Once you have received your report, please review it. This report will show you grammatical, punctuation, and spelling errors that can easily be fixed. Take the extra few minutes to review instead of getting counted off for these mistakes. Review your similarities. Did you forget to cite something? Did you not paraphrase well enough? Is your paper made up of someone else’s thoughts more than your own? Visit the Writing Center in the Student Success Center, under the Resources tab in Loud-cloud for tips on improving your paper and SI score.

• Late Policy

The university’s policy on late assignments is a 10% penalty PER DAY LATE. This also applies to late DQ replies. Please communicate with me if you anticipate having to submit an assignment late. I am happy to be flexible, with advance notice. We may be able to work out an extension based on extenuating circumstances. If you do not communicate with me before submitting an assignment late, the GCU late policy will be in effect. I do not accept assignments that are two or more weeks late unless we have worked out an extension. As per policy, no assignments are accepted after the last day of class. Any assignment submitted after midnight on the last day of class will not be accepted for grading.

• Communication

Communication is so very important. There are multiple ways to communicate with me: Questions to Instructor Forum: This is a great place to ask course content or assignment questions. If you have a question, there is a good chance one of your peers does as well. This is a public forum for the class. Individual Forum: This is a private forum to ask me questions or send me messages. This will be checked at least once every 24 hours.
