In 1965 researchers used random digit dialing to call 1300 people and ask what obstacles kept them from  exercising 

A. Convenience sampling was used since 1300 phone numbers that were selected.

B. Systematic sampling was used since phone numbers were selected from a list using a fixed interval between phone numbers. 

C. Simple random sampling was used since each number had an equal chance of being dialed so all samples of 1300 phone numbers had an equal chance of being selected.

D. Cluster sampling was used since the phone numbers were divided into groups several groups were selected and each number in those groups was called

For this assessment, you will identify a published research article either in the print literature or online in the Capella University Library. Your article must be based on empirical (data-based) research; qualitative or purely descriptive research is not appropriate. Select a journal article in your career specialization that reports a correlation, a t test, a one-way ANOVA, or some combination of these test statistics. The library guides listed in the Resources area can help you to locate appropriate articles.

The intent of this assessment is to:

  • Expose you to professional literature in your discipline.
  • Provide practice in the interpretation of statistical results contained in an empirical (data-based) journal article.
  • Provide practice in writing and thinking in a concise and economical manner that is typical of scientific discourse.

You will summarize the article in a maximum of 600 words using the DAA Template located in the Resources area under the Required Resources heading. Specific instructions for completing each section of the DAA Template are listed below.

You may use some of the author’s own words to summarize the article with proper citation, but avoid lengthy direct quotes (such as copying multiple sentences or paragraphs verbatim). You should not exceed the limit of 600 words. This is a situation where less is better.

Step 1: Write Section 1 of the DAA

  • Provide a brief summary of the journal article.
  • Include a definition of the specified variables (predictor, outcome) and corresponding scales of measurement (nominal, continuous).
  • Specify the sample size of the data set.
  • Discuss why the journal article is relevant to your career specialization.

Step 2: Write Section 2 of the DAA

  • Discuss the assumptions of the statistical test used in the journal article.     
    • If possible, identify information in the article about how these assumptions were tested.
    • If no information on assumptions is provided, consider this as a limitation of the reported study.

Step 3: Write Section 3 of the DAA

  • Specify the research question from the journal article.
  • Articulate the null hypothesis and alternative hypothesis.

Step 4: Write Section 4 of the DAA

  • Report the results of the statistical test using proper APA guidelines. This includes:     
    • The statistical notation (such as r, t, or F).
    • The degrees of freedom.
    • The statistical value of r, t, or F, and the p value.
  • Report the effect size and interpretation if one is provided.
  • Interpret the test statistic with regard to the null hypothesis.

Step 5: Write Section 5 of the DAA

  • Discuss the conclusions of the statistical test as it relates to the research question.
  • Conclude with an analysis of the strengths and limitations of the study reported in the journal article

Hello again and yet I again I find myself struggling with the weekly assignments. I always seem to start out strong but somewhere along the process of solving the algebraic equations I end up making simple mistakes making the answers completely off.  For example, this week alone I find myself spending an entire day in trying come up with the correct solution and when I realize the simple mistakes, I made makes me want to slap myself upside the head.  Good thing I am stubborn or else I would have given up after the first week. It would be nice if Walmart would utilize these equations in order to come up with a minimum number of cashiers to meet customer demands.  I always manage to get line whereby the customer either argues about the price, the scan bar is missing, or else they stumble through a bundle of coupons, trying to find the correct ones.  Oh, and the ones that still write checks and then decide to balance their checkbooks while others are patiently (or impatiently) awaiting their turns.  I try to just ignore the situation and mind my own business.  Now my sister in the other hand did use similar calculations in determining the number of tellers to put on the line at her bank.  She once told me that she held them to x number of minutes per customer and how many they could/should expect to serve.  When doing my banking at her location I never had to wait for more than a minute or two to be served and all my needs met in a couple of minutes.  Like Walmart, the Army has much to be desired when it comes to administrative personnel meeting timelines.  We would have “taskers” placed upon us leaders that were expected to be met within a certain period.  Afterwards it was the administrator’s job to compile all completed taskers and compile them into a report and submit for higher command.  I don’t know as to how many times I had to answer for not meeting timelines when in fact we had.  To prevent these situations occurring on a frequent basis I would sit down with my folks and lay out a timeline to get tasks completed by priority. The first hour of their day was devoted to getting all important soldiers needs accomplished, i.e. promotions and awards along with following up on previous submissions.  The following hour was committed to getting all accomplished training compiled with scores followed by updating all soldier individual training folders.  Now there were many more tasks that were organized for their daily schedules, but I feel you all get the idea.  I gave them time constraints and goals to meet and would use this data when time came for scheduled ratings (NCOERs). 

As for the scenarios presented to us, I will say that in trying to hold costs down by only having enough people to meet expected customer rates can be a setup for failure.  Yes, utilizing more people will cost more but not having enough will end up costing so much more in terms of customer satisfaction and loyalty.  If I experience poor service due to excessive waiting times, I will do everything within my powers to avoid giving them repeat business.

This theory is important because it allows you to figure out how many customer service representatives that you need in order to bring down your wait time to 30 seconds. If you did not have this theory you wouldn’t be able to figure out how many people you needed to hire in order to reach your goal. This is also the same for case 2 because you want to know how many tellers you will need to get your waiting time down to what it needs to be. This will help a company keep their customers happy and prevent them from spending too much money or hiring too many people. 

Imagine if you had a call center that received phone calls about customer service for a product. You would want to know how many people to hire from the average number of calls so you could reduce the wait time that could save you money and create a happy customer. The average calls coming in would allow you to figure out how many employees you would need at any given time. This is the same with restaurants and customers coming in on the weekends. It is most likely going to be a larger number of people on the weekends than on weeknights so more people should be scheduled for those nights.

Several large observational studies suggested that women who take hormones such as estrogen after menopause have a lower risk of a heart attack than women who do not take hormones. Hormone replacement became popular. But in 2002, several careful experiments showed that hormone replacement does not reduce heart attacks. The National Institutes of Health, after reviewing the evidence, concluded that the observational studies were wrong. Taking hormones after menopause quickly fell out of favor.

a) Explain the difference between an observational study and an experiment to compare women who do and don’t take hormones after menopause.
