Create a baseline demographic table and a 2-to-3 page narrative summary
Statistics is the art and science of data collection and interpretation. It is an art because it requires a combination of creativity, an eye for what makes sense, and personal judgment about how to use the end result. It is a science because it requires a systematic way of organizing, transforming, analyzing, describing, and interpreting data. Even if you dislike math, you can still enjoy statistics because it is not just about doing calculations or performing mathematical gymnastics. Most of the mathematics that makes learners uncomfortable is hidden inside statistical technological tools that we can use with relative ease in health care to make important discoveries. So relax—we are going to let technology do most of the work!
In this assessment, we focus on the cornerstone of quantitative research: the variable. One of the many things that makes the health care field so fascinating (and challenging) is the variation we find from one human to the next. Age, gender, eye color, heart rate, ethnicity, emotional response, and food preferences are some of the differences we find in our communities around the globe. In the language of statistics, each of these characteristics is called a variable. Some characteristics, like gender, have little variation, while other characteristics, like age, can have a much larger amount of variation.
Throughout this course, you will see that variables have special names based on their functional roles in the experiment. For example, when a variable is associated with the intervention (such as treatment, where we design the experiment to allow for only two options: practicing yoga versus not), it is referred to as an independent variable.
And when a variable is associated with an outcome in the experiment (for example, stress—which we decide, arbitrarily, will have only three possible levels: high, medium, and low) that is used to measure the direct consequences of the experimental treatment, we refer to this as a dependent variable.
The sneaky thing about statistics is that depending on the circumstances, the independent variable is often referred to in other terms, such as the controlled, explanatory, or predictor variable. If you consider this briefly, the names make sense because you are controlling who gets which treatment, where the treatment really is the key factor in explaining (or predicting) any outcome. The dependent variable may also be referred to as response, outcome, output, or experimental variable. In this course, we will try to be fairly consistent, using the terms independent and dependent.
Overview
The baseline demographic table plays an important role in reporting study results. It summarizes key characteristics of participants numerically (such as age, gender, and ethnicity) at the beginning of a study, before any intervention takes place. Baseline demographic tables are often among the first tables found in the results section of capstone papers, dissertations, and peer-reviewed publications as well. For this assessment, you will create a baseline demographic table and narrative summary using the linked Resources.

How to Create a Demographic Table
Let’s look first at what a demographic (or baseline characteristics) table looks like in healthcare journals. Look in Google Images to find other examples.
Note that this column has the variables of interest
N = number of study participants
MEAN for interval/ratio data and (standard deviation) values
These columns report the data. In this case there were two groups that were studied.
Numbers of participants and (%) for categorical data
Click on INSERT Table functions at the top of MS Word. You can then select the number of rows and columns you need for your table.
Note that the variable column also has information about how the data is reported, such as the unit of measure (such as yrs) and the statistics being used (for example, mean, SD, n, %).

SCORE A+ WITH HELP FROM OUR PROFESSIONAL WRITERS – Create a baseline demographic table and a 2-to-3 page narrative summary
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. Create a baseline demographic table and a 2-to-3 page narrative summary
- 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. Create a baseline demographic table and a 2-to-3 page narrative summary
- 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.
