Week 3 Assignment – Microeconomics Case Study

Week 3 Assignment – Microeconomics Case Study
Instructions
In this exercise, you will demonstrate your ability to find microeconomic data from public sources and to make a spreadsheet in Excel.
Microeconomic data are numbers about a single industry. Automobile sales numbers are microeconomic data. Unemployment numbers for the entire country are not microeconomic data.
Start by choosing an industry that interests you.
Remember that an industry is a group of companies that do the same thing. For example, Ford is a company; automobile manufacturing is an industry.
Choose a microeconomic variable for your industry.
It could be prices, sales, production, advertising, or investment.
Using the library’s Statista resource, find three years of this microeconomic variable for your industry. For example, you might find automobile sales data for 2017, 2018, and 2019.
Go to Statista.
Log in using your Strayer credentials.
Type your industry name in the “Statista Search” space and click Statista Search.
Choose one of the options that has three years of annual data.
Prepare an Excel spreadsheet that has two columns and four rows. In cell A1, type in the industry you selected and bold the text. In the heading for cell A2, type “Year.” In cells A3, A4, and A5 descending below this heading, type the years for your data. In the automobile example, this would be 2017, 2018, and 2019.
In the heading for column two, cell B2, type the name of the variable you chose. For example, it could be “Sales.” In the cells below this heading, type the sales data for each of the three years.
Underneath your table, type “Source:” and then paste the URL of the source where you found your data.
See the Excel example below.

Module 2 Discussion: Agents of Socialization, Categories, and DevianceContains unread posts

Must post first.
Utilizing evidence with in-text citations from course materials, answer parts A and B in an initial posting. Your initial answer should be a minimum of 300 words, and demonstrate an ability to think critically about ideas and thoughts, and specifically articulate a position that takes into account the complexity of an issue.

Initial Posting (30 points):
Select one agent of socialization (i.e. family, friends, school, or the mass media) and explain how it has impacted your perceptions of formal and informal deviance.
Next, consider how changing a category you belong to (e.g. race, gender, sexual orientation, or social class) might shift the way your previously discussed agent of socialization influences your perceptions of deviance.
NOTE: Include a works cited page for your initial response

Response to a Classmate (20 points):
After submitting your initial post, you are also required to respond to at least one other student’s posting. In a minimum of 200 words, again demonstrate an ability to critically think about sociological issues. When providing your response, be sure to meet the following criteria:
Considering what a classmate wrote in Part B of their assignment, how changing a demographic characteristic might reshape the way an agent of socialization shapes their perceptions of deviance, make an argument whether the conflict, functionalist, or symbolic interactionist paradigm is best equipped to interpret their explanation.
Using in-text citations, provide evidence to support your position.
Include a works cited page for your response to a peer.
IMPORTANT: Please note that it is your responsibility to ensure your work submits correctly. This can easily be verified by viewing submissions.
