Unit IV Article Review
Wade and Tavris explain that various factors combine to influence one’s thinking patterns and behaviors. Most would agree that we are inundated with outside influences on a continuous basis. The need to stay connected to various forms of media is growing by leaps and bounds. Have you ever wondered what impact media consumption could be having in your life? Can viewing violent acts lead to vicious behaviors later? One particular area worthy of closer examination relates to one’s environment and how extraneous information can intrude our waking and restful thoughts. In fact, research conducted by Van den Bulck, Cetin, Terzi, and Bushman (2016) revealed that violent and sexual media viewing can not only influence one’s memories, but this content can have an impact on dreams as well. Read the article listed below. Van den Bulck, J., Cetin, Y., Terzi, O., & Bushman, B. J. (2016). Violence, sex, and dreams: Violent and sexual media content infiltrate our dreams at night. Dreaming, 26(4), 271-279.

Your review should also relate back to the information covered in Unit IV. In your review, be sure to include the following items: Briefly introduce and summarize the article. Identify the authors’ main points. Explain how the study’s results may differ if conducted in the United States as opposed to using Turkish participants. Keep in mind that Turkey has stricter sexual media censorship rules than the United States, and violations of such can produce regulation fines. Explain additional factors that influence learning, conditioning, and behaviors as outlined in the textbook. Examine how one’s dreams influence external behaviors. Describe the impact that violence and social media can have on behaviors. Relate the article back to this course. Does it support the information in your textbook? Your article review must be a minimum of two pages in length. You must reference the assigned article and your textbook. If necessary, you may use other scholarly sources to support your review as well. All sources used must be referenced; paraphrased and quoted material must have accompanying citations. Please be sure to cite any outside sources, and format your paper in accordance with proper APA formatting.

Descriptive Statistics

Descriptive Statistics

The Statistics Project assignment has been broken down into multiple parts and you will complete these parts throughout the course. This week’s assignment allows you to become familiar with opening data and viewing it in Microsoft® Excel® and using the Analysis Toolpak. In research, the individual data points are entered into databases, but for the purpose of this course, the data is provided in a spreadsheet for you in the Happiness and Engagement Dataset.
Imagine you have been asked to enhance workplace happiness and engagement at your company. You have conducted a survey and gathered data on the gender, age, relationship with direct supervisor, telecommute schedule, relationship with coworkers, along with the ratings for workplace happiness and workplace engagement for 50 individuals in your department. You must determine what variables affect workplace happiness and engagement. The first step is to run descriptive statistics on each variable to learn more about the data you have collected.
Calculate descriptive statistics for the following variables in the provided Microsoft® Excel® dataset:

  • Gender
  • Age
  • Relationship with Direct Supervisor
  • Telecommute Schedule
  • Relationship with Coworkers
  • Workplace Happiness Rating
  • Workplace Engagement Rating

Write a 125- to 175-word summary of your interpretation of the descriptive results for each variable. Copy and paste the Microsoft® Excel® output below your summary.
Format your summary according to APA guidelines.

Introduction to Hypothesis Testing Table
Identify whether each research scenario listed in the left column of the top of the matrix, would be a one- or two-tailed test and then justify your decision. For each research scenario in the bottom of the matrix, write what the null and alternative hypotheses would be.

Research Scenario One-tail or two-tail test Justification
A local dermatologist claims that more than 30% of mole biopsies are unnecessary. Last month at his clinic, 210 out of 634 had benign biopsy results. Is there enough evidence to reject the dermatologist’s claim?
