Tutorial help on Excel® and Word functions can be found on the Microsoft® Office website. There are also additional tutorials via the web offering support for Office products.

Assignment Steps

Identify a business problem or opportunity at a company where you work or with which you are familiar. This will be a business problem you use for the individual assignments in Weeks 3-5. It should be a problem/opportunity for which gathering and analyzing some type of data would help you understand the problem/opportunity better.

Identify a research variable within the problem/opportunity that could be measured with some type of data collection.

Consider methods for collecting a suitable sample of either qualitative or quantitative data for the variable.

Consider how you will know if the data collection method would be valid and reliable.

Develop a 1,050-word analysis to describe a company, problem, and variable including the following in your submission:

  • Identify the name and description of the selected company.
  • Describe the problem at that company.
  • Identify one research variable from that problem. Describe the methods you would use for collecting a suitable sample of either qualitative or quantitative data for the variable (Note: do not actually collect any data).
  • Analyze how you will know if the data collection method would generate valid and reliable data (Note: do not actually collect any data).

Format your assignment consistent with APA guidelines.

QNT275 University of Phoenix Week 2 Movie Genre Statistical Data Analysis

Purpose of Assignment

This assignment provided students with practice in understanding the relationship of averages and standard deviation to make an informed business decision about the gross income performance of each movie genre. Students will learn to implement the use of these statistical measures for better business decision-making.

Resources: Week 2 Videos; Week 2 Readings; Statistics Lab

Tutorial help on Excel® and Word functions can be found on the Microsoft® Office website. There are also additional tutorials via the web offering support for Office products.

Assignment Steps

Refer to Mini-Project Movie Data Set.

Analyze and write a report summarizing this data. This report should include answers to at least the following questions:

  1. Calculate the summary measures (the mean, standard deviation, five-number summary, and interquartile range) of the total gross income for each movie genre.
  2. Which genre had greater variability in total gross income? Explain why.
  3. Draw a box-and-whisker plot of a movie’s length of time (minutes) by genre. Are there any differences in movie lengths when compared across genres? Are there any outliers?

Use the mean movie gross income for each genre to compare the movie opening gross income.

Choose an appropriate statistical measure to compare the consistency of movie gross income.

Make the calculations and write a 700-word report comparing the total movie gross income and the consistency of movie opening gross by genre.

    QNT561 Phoenix Annual food spending & Household Income Analysis

    Resources: Microsoft Excel®, Signature Assignment Databases, Signature Assignment Options, Part 3: Inferential Statistics

    Scenario: Upon successful completion of the MBA program, say you work in the analytics department for a consulting company. Your assignment is to analyze one of the following databases:

    • Manufacturing
    • Hospital
    • Consumer Food
    • Financial

    Select one of the databases based on the information in the Signature Assignment Options.

    Provide a 1,600-word detailed, statistical report including the following:

    • Explain the context of the case
    • Provide a research foundation for the topic
    • Present graphs
    • Explain outliers
    • Prepare calculations
    • Conduct hypotheses tests
    • Discuss inferences you have made from the results

    This assignment is broken down into four parts:

    • Part 1 – Preliminary Analysis
    • Part 2 – Examination of Descriptive Statistics
    • Part 3 – Examination of Inferential Statistics
    • Part 4 – Conclusion/Recommendations

    Part 1 – Preliminary Analysis (3-4 paragraphs)

    Generally, as a statistics consultant, you will be given a problem and data. At times, you may have to gather additional data. For this assignment, assume all the data is already gathered for you.

    State the objective:

    • What are the questions you are trying to address?

    Describe the population in the study clearly and in sufficient detail:

    • What is the sample?

    Discuss the types of data and variables:

    • Are the data quantitative or qualitative?
    • What are levels of measurement for the data?

    Part 2 – Descriptive Statistics (3-4 paragraphs)

    Examine the given data.

    Present the descriptive statistics (mean, median, mode, range, standard deviation, variance, CV, and five-number summary).

    Identify any outliers in the data.

    Present any graphs or charts you think are appropriate for the data.

    Note: Ideally, we want to assess the conditions of normality too. However, for the purpose of this exercise, assume data is drawn from normal populations.

    Part 3 – Inferential Statistics (2-3 paragraphs)

    Use the Part 3: Inferential Statistics document.

    • Create (formulate) hypotheses
    • Run formal hypothesis tests
    • Make decisions. Your decisions should be stated in non-technical terms.

    Hint: A final conclusion saying “reject the null hypothesis” by itself without explanation is basically worthless to those who hired you. Similarly, stating the conclusion is false or rejected is not sufficient.

    Part 4 – Conclusion and Recommendations (1-2 paragraphs)

    Include the following:

    • What are your conclusions?
    • What do you infer from the statistical analysis?
    • State the interpretations in non-technical terms. What information might lead to a different conclusion?
    • Are there any variables missing?
    • What additional information would be valuable to help draw a more certain conclusion?

    Format your assignment consistent with APA format.
