Purpose of Assignment

The purpose of this assignment is to provide students the opportunity to demonstrate mastery of their ability to apply statistical concepts to business situations to inform data-driven decision-making. The project is a 3-week project, with part 1 in Week 3, part 2 in Week 4, and part 3 in Week 5. In Week 3, students identify the organization, problem, research variable, methods for collecting data, and show mastery of validity and reliability as applied to data-collection methods.

Resources: Week 3 Videos; Week 3 Readings; Statistic 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

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.
