Confidence Intervals
In everyday terms, a confidence interval is the range of values around a sample statistic (such as mean or proportion) within which clinicians can expect to get the same results if they repeat the study protocol or intervention, including measuring the same outcomes the same ways. As you ask yourself, “Will I get the same results if I use this research?”, you must address the precision of study findings, which is determined by the Confidence Interval. If the CI around the sample statistic is narrow, you can be confident you will get close to the same results if you implement the same research in your practice.
Consider the following example. Suppose that you did a systematic review of studies on the effect of tai chi exercise on sleep quality, and you found that tai chi affected sleep quality in older people. If, according to your study, you found the lower boundary of the CI to be .49, the study statistic to be 0.87, and the upper boundary to be 1.25, this would mean that each end limit is 0.38 from the sample statistic, which is a relatively narrow CI.
(UB + LB)/2 = Statistic [(1.25 + .49)/2 = .87]
Keep in mind that a mean difference of 0 indicates there is no difference; this CI does not contain 0. Therefore, the sample statistic is statistically significant and unlikely to occur by chance.
Because this was a systematic review, and tai chi exercise has been established from the studies you assessed as helping people sleep, based on the sample statistics and the CI, clinicians could now use your study and confidently include tai chi exercises among possible recommendations for patients who have difficulty sleeping.
Now you can apply your knowledge of CIs to create your own studies and make wise decisions about whether to base your patient care on a particular research finding.
Initial Post Instructions
Find an example of a confidence interval in the news, scholarly source or medical journal. Summarize the article/study. Does the article/study include the sample size and the level of confidence used to create the confidence interval? Explain what the confidence interval means in context of the news article or scholarly source.
Follow-Up Post Instructions
Respond to at least two peers or one peer and the instructor. Further the dialogue by providing more information and clarification.
Here are some suggested responses
How do you think the confidence interval that was presented in the study was calculated?
Explain the mathematical concepts could you extract from this article/study.

Differentiate between correlation and causation in a way that connects to your ideal job.

Exam Content
Now that you’ve gotten a foundation in research, data, and analysis you’ll be better prepared to review criminal justice studies and use relevant data to help you solve problems and make decisions. In this assignment, you’ll demonstrate your knowledge of how research and inferential statistics might be used in criminal justice operations, such as police, courts, and corrections.
Write an 875- to 1,050-word paper in which you do the following:
Describe your ideal job in criminal justice.
Explain how you might use published research statistics to help you solve problems and make decisions in your ideal job. Provide 2 examples of how you could use published criminal justice research in your ideal job.
Differentiate between correlation and causation in a way that connects to your ideal job.
Identify potential applications of correlation and regression within management or research for your chosen criminal justice field.
Describe how techniques involving association, correlation, and prediction (as in regression) help form policy and operational decisions for more effective criminal justice practices.
Cite a minimum of 2 peer-reviewed sources.
Format your paper according to APA guidelines.

The result of this would be an increase in taxes which in turn will increase the prices of anything that you buy which eventually will trigger inflation”

“I picked this topic to understand how covid has impacted the livelihood of our people, especially in terms of changing their lifestyle. we see great resignations coming through which are happening across all sectors and the main reason that I could figure out is people are now choosing passion over career. Some or the other way it has greatly impacted our economic growth because of the fact that we are losing out people from the tax paying pool which is adversely impacting Govt.’s revenue which they usually earn through taxes. The result of this would be an increase in taxes which in turn will increase the prices of anything that you buy which eventually will trigger inflation”

After you listen, reflect on what you heard.

Part 1: 150 words
The early planning stage for a presentation requires you to focus in on your topic and purpose statement and to begin gathering research and support for that purpose statement. In a multi-paragraph reflection, a minimum of 150-words, reflect on the skills you used as you started to prepare for your Portfolio Presentation.
In your reflection, be sure to discuss the following:
Consider your skills in research and planning. Give examples of the research and planning process you used to prepare for your Portfolio Presentation.
Describe your strengths and the areas you struggled with during this process.
Discuss how the development of this skill will help you as you move forward in your education and career.
Part 2: 150 words
The website American Rhetoric ranks Martin Luther King, Jr’s “I Have a Dream” speech as the top-ranking speech of the 20th century. While you have more than likely heard portions of the speech, the power of the speech can only be heard when heard full-length. Click on the link below to listen to the 16 minute, 27-second audio file of Martin Luther King Jr’s speech.
Audio file: “I Have a Dream”
After you listen, reflect on what you heard. In your initial post, address the following:
Discuss King’s use of language to inspire his audience. Give examples of the powerful words and language King uses.
Explain what you perceive as the power behind these words and how they enhance the impact of this speech.
Explain why you believe 137 leading scholars chose this particular speech to represent the best speech of the 20th century.I Have a Dream
Psy Part 3: 150 words
In the lecture, you learned about many cognitive processes, including perception. Perception involves how people interpret and make sense of the world around them. As you learned, there are a variety of perceptual errors, including the recency effect and the halo effect. These errors help to explain why an individual’s perceptions might not correspond with reality and why people can have such differing perceptions from one another.
For discussion, you will apply this material to your personal or professional life. Please address the following in your initial post:
Summarize a time where your perception differed greatly from that of another person.
In so doing, make sure to describe your own perception and the other person’s and explain whether either of you might have been displaying one of the perceptual errors you learned about in lecture (halo effect, recency effect, etc.).
Detail what the results of this perceptual difference were. For instance, did it lead to hostility or difficulty finding common ground?
Outline specific ways this situation could have been handled differently using tips from lecture.
Identify some strategies you will use in the future to ensure you are perceiving reality as accurately as possible and not succumbing to perceptual errors.
Part 4: 150 words
Utilize the Bryant and Stratton College Library Page to find a scholarly research article the utilizes a Pearson Correlation Analysis. You are welcome to search for an article related to your Portfolio Project and utilize this in the literature review section of your project.
Which research article did you choose? Give the article reference.
Give a brief general summary of the research article objectives.
What variables did the researchers test in the correlation analysis?
Give a brief summary of the major findings of the correlation analysis.
Do you think the study could have been improved? Are there additional variables that may be related to the topic that were not included?
