Opioid Crisis and Bus. Administration/Leadership statistics

Posted on | by

 

Focus on the Daytona, Ohio opioid crisis in general. Define a specific problem related to the crisis in your discipline (Business Administration/Leadership ). Begin to determine a solution for your specific problem. Your solution should be specific, direct, and attainable (for instance, do not choose a solution, such as reforming the entire criminal justice system or replacing the city board of trustees, that is too broad in scope).

Locate a valid and reliable article relevant to your proposed solution. The article should contain data that contribute to a solution to the epidemic from your field’s perspective. Note that you may not find research on the exact solution you have proposed, but the article may contain data relevant to your solution. Do not submit an article with data about the opioid crisis only. The article should support your proposed solution in a meaningful way.

Statistics has a language of its own. Here is a great resource to help you with statistical symbols and their meanings.

· Give the topic of the article and explain why it is pertinent to your specific role.

· Discuss why the statistical procedures and/or data are appropriate.

Application of statistics

In real-life applications, statistics helps us analyze data to extract information about a population. In this module discussion, you will take on the role of Susan, a high school principal. She is planning on having a large movie night for the high school. She has received a lot of feedback on which movie to show and sees differences in movie preferences by gender and also by grade level.

She knows if the wrong movie is shown, it could reduce event turnout by 50%. She would like to maximize the number of students who attend and would like to select a PG-rated movie based on the overall student population’s movie preferences. Each student is assigned a classroom with other students in their grade. She has a spreadsheet that lists the names of each student, their classroom, and their grade. Susan knows a simple random sample would provide a good representation of the population of students at their high school, but wonders if a different method would be better.

You can review the student demographics here: Module One Discussion Data PDF. – Attached to the assignment in a screenshot

In your initial discussion post, specifically, address the following:

Introduce yourself and describe a time when you used data in a personal or professional decision. This could be anything from analyzing sales data on the job to making an informed purchasing decision about a home or car.
Describe to Susan how to take a sample of the student population that would not represent the population well.
Describe to Susan how to take a sample of the student population that would represent the population well.
Finally, describe the relationship of a sample to a population and classify your two samples as random, systematic, cluster, stratified, or convenience.

 

 

 

 

Probabilities With The Binomial Distribution

Posted on | by

Every day, 17% of the U.S. population with Internet access checks the weather in that way. For a sample of 5 people taken on any given day:
Construct a table of the binomial probability distribution for this case.
View this information using a histogram.
Calculate the mean, variance, and standard deviation for this distribution.
Calculate the probability that at least 3 people in the sample checked the weather that day.
According to a recent infographic (NAMI: National Alliance on Mental Illness, n.d.), “1 in 20 U.S. adults experience serious mental illness” in the United States. If a random sample of 20 students is selected from a large school district,
Construct a table of the binomial probability distribution for this case.
View this information using a histogram.
Calculate the mean, variance, and standard deviation for this distribution.
If 3 of the students were diagnosed with serious mental illness, would this be a signal about the school district having a problem with mental health among the students being above the national score?

Environmental factors might impact children’s development

Posted on | by

 

 

How do you think current environmental factors (Covid-19, the pandemic response, and all its effects) might impact children’s development (physical, cognitive, psychosocial) in the near future and long term?

Focus on children, 0-18 years.

There are many ways to answer this question, including:

What have you observed in the children you know?

What are school experiences like after an extended period of remote instruction? Sports? Afterschool programs? Social interactions?

Consider the incredible range of remote participation students brought to their classroom when they returned. Are the children who played video games during Zoom classes, or the ones who couldn’t connect to the internet, as ready for the next grade’s work as the students who worked diligently through the remote period? What factors made some kids diligent and others unengaged?

How has the development of younger children been impacted? For three-year-olds, two years is more than half of their lives. Do masks impede language development? Does social distancing impact early friendships? Do they have enough opportunities to run freely and visit playgrounds? How comfortable are they meeting new people?

How have isolation and social distancing impacted all children’s social skills? Will the wearing of masks affect the ability to correctly read and interpret social cues?

How might physical development be impacted?

Do you think some children will be unaffected by the pandemic response? Why, or why not?

(These questions are just suggestions. There are many ways to answer this question.)

Please address all domains of development (physical, cognitive, psychosocial) in your answer.

Remember that the passage of time is part of the environment.
