## What are some differences between sample standard deviation and population standard deviation?

The number of vacation days taken by the employees of a company is normally distributed with a mean of 14 days and a standard deviation of 3 days. Is this a case of sample standard deviation or population standard deviation? What are some differences between sample standard deviation and population standard deviation? For the next employee, what is the probability that the number of days of vacation taken is less than 10 days? What is the probability that the number of days of vacation taken is more than 21 days? Discuss the solutions and an explanation. Respond to your peers’ posts and offer your feedback on this topic

## How does a multiple-baseline design differ from a reversal design?

Transtutors Week five June 16, 2019 Use the APA format to support all the answers, with a minimum of 5 scholarly resources. Answer questions 2, 3, 4, 8, and 8 from Chapter 13, Exercises, pp. 360 On Key Concepts, from Jackson and Trochim, Donnelly, and Arora. The Title of the book is: Research Methods and Statistics: A Critical Thinking Approach 4th edition. These are the questions listed numbers 1 to 5 in this attachment, plus other questions on part one and part two in this attachment. Part one of the assignment answers even numbered questions of chapter 13, page 360, of Jackson (2012), plus six more questions. Part two of the assignment answers six questions. The question in both part one and part two are list as follows. Part One A psychology professor is interested in whether implementing weekly quizzes improves student learning. She decides to use the weekly quizzes in one section of her introductory psychology class and not to use them in another section of the same course. Which type of quasi-experimental design do you recommend for this study? If the psychology professor in above question had access to only one section of introductory psychology, describe how she might use a single group design to assess the effectiveness of weekly quizzes. Which of the three single group designs would you recommend? Identify some possible confounds in each of the studies you outlined in your answers to question 1 and 2 above. Give the reasons a researcher might choose to use a single-case design. How does a multiple-baseline design differ from a reversal design? Describe the advantages and disadvantages of quasi-experiments? What is the fundamental weakness of a quasi-experimental design? Why is it a weakness? Does its weakness always matter? If you randomly assign participants to groups, can you assume the groups are equivalent at the beginning of the study? At the end? Why or why not? If you cannot assume equivalence at either end, what can you do? Please explain. Explain and give examples of how the particular outcomes of a study can suggest if a particular threat is likely to have been present. Describe each of the following types of designs, explain its logic, and why the design does or does not address the selection threats discussed in Chapter 10 of Trochim, Donnelly, and Arora (2016): a. Non-equivalent control group pretest only b. Non-equivalent control group pretest/posttest c. Cross-sectional d. Regression-Discontinuity Why are quasi-experimental designs used more often than experimental designs? One conclusion you might reach (hint) after completing the readings for this assignment is that there are no bad designs, only bad design choices (and implementations). State a research question for which a single-group post-test only design can yield relatively unambiguous findings Part Two – Answer the following questions: What research question(s) does the study address? What is Goldberg’s rationale for the study? Was the study designed to contribute to theory? Do the results of the study contribute to theory? For both questions: If so, how? If not, why not? What constructs does the study address? How are they operationalized? What are the independent and dependent variables in the study? Name the type of design the researchers used. What internal and external validity threats did the researchers address in their design? How did they address them? Are there threats they did not address? If so, how does the failure to address the threats affect the researchers’ interpretations of their findings? Are Goldberg’s conclusions convincing? Why or why not?

## Identify the relationship between socioeconomic status and intimidate partner violence in homosexual men.

Hi,For one of my assignments I’ve been required to design study. For the study I have decided to look at the relationship between socioeconomic status and intimidate partner violence in homosexual men. I’m at the data analysis stage of the study design where I need to highlight what statistical methods I will use to assess the variables any explain why they are the best choices. I’m comparing intimate partner violence (IPV) (which is a binary yes/no, dependent variable) against income (which is a continuous Independent variable). i’m Also comparing IPV against education, which is an ordinal variable (eg phd, masters, bachelor, high school).What are the best statistical methods to make these two comparisons and explain why + what assumptions are being made when using these tests.Assuming the answer provided is correct and the marker agrees, I will pay an additional sum afterwards.

We stronglyrecommend you to refer to the Academic Learning Skills materials available in the Moodle. Fordetails please click the link http://moodle.kent.edu.au/kentmoodle/course/view.php?id=5 anddownload the file “Harvard Referencing Workbook”. Appropriate academic writing and referencingare inevitable academic skills that you must develop and demonstrate.We recommend a minimum of FIVE references unless instructed differently by your lecturer. Unlessspecifically instructed otherwise by your lecturer, any paper with less than FIVE references may befailed. Work that includes sources that are not properly referenced according to the “HarvardReferencing Workbook” will be penalised.Marks will be deducted for failure to adhere to the word count – as a general rule, you may go overor under by 10% than the stated length.GENERAL NOTES FOR REFERENCINGHigh quality work must be fully referenced with in-text citations and a reference list at the end. Werecommend you work with your Academic Learning Support (ALS) site(http://moodle.kent.edu.au/kentmoodle/course/view.php?id=5) available in Moodle to ensure thatyou reference correctly.References are assessed for their quality. You should draw on quality academic sources, such asbooks, chapters from edited books, journals etc. Your textbook can be used as a reference, but notthe lecture notes. We want to see evidence that you are capable of conducting your own research.Also, in order to help markers, determine students’ understanding of the work they cite, all in-textreferences (not just direct quotes) must include the specific page number/s if shown in the original.Before preparing your assignment or own contribution, please review this ‘YouTube’ video byclicking on the following link: Plagiarism: How to avoid itPLAGIARISM: HOW TO AVOID ITYou can search for peer-reviewed journal articles, which you can find in the online journal databasesand which can be accessed from the library homepage. Wikipedia, online dictionaries and onlineencyclopaedias are acceptable as a starting point to gain knowledge about a topic, but should not beoverused – these should constitute no more than 10% of your total list of references/sources.Additional information and literature can be used where these are produced by legitimate sources,such as government departments, research institutes such as the NHMRC, or internationalorganisations such as the World Health Organisation (WHO). Legitimate organisations andgovernment departments produce peer reviewed reports and articles and are therefore very usefuland mostly very current.

## Determine the correlation coefficient between production budget and box office.

1. Make and interpret the meaning of a 95% confidence interval for the “% of box office before nom” for all movies using the data given for the % of box office before nomination for this sample of movies. 2. Conduct a hypothesis test to determine whether the box office for films released in December or November is higher than the mean box office for films released in other months using a = 0.025 3. Determine the correlation coefficient between production budget and box office (dependent variable . .) and interpret its meaning. Plot a scatterplot. 4. Find the least squares linear regression equation for production budget (independent variable) and box office (dependent variable ). Use the equation to estimate the box office for a movie with a $45 million production budget. Interpret the meaning of the slope and the y-intercept (be specific using the context provided here).

## Analyze what combination of factors make a customer more likely to take out a personal loan.

Universal Bank is a relatively young bank growing rapidly in terms of overall customer acquisition. Universal bank wants to convert its liability customers (depositors) into personal loan customers (while retaining them as depositors). A campaign that the bank ran last year for liability customers showed a healthy conversion rate of over 9% success. This has encouraged the retail marketing department to devise smarter campaigns with better target marketing. The goal of our analysis is to model the previous campaign’s customer behavior to analyze what combination of factors make a customer more likely to take out a personal loan.
