A marketing company based out of New York City is doing well and is looking to expand internationally.

Scenario Background:
A marketing company based out of New York City is doing well and is looking to expand internationally. The CEO and VP of Operations decide to enlist the help of a consulting firm that you work for, to help collect data and analyze market trends.

You work for Mercer Human Resources. The Mercer Human Resource Consulting website lists prices of certain items in selected cities around the world. They also report an overall cost-of-living index for each city compared to the costs of hundreds of items in New York City (NYC). For example, London at 88.33 is 11.67% less expensive than NYC.

More specifically, if you choose to explore the website further you will find a lot of fun and interesting data. You can explore the website more on your own after the course concludes.

find the 2018 data for 17 cities in the data set Cost of Living. Included are the 2018 cost of living index, cost of a 3-bedroom apartment (per month), price of monthly transportation pass, price of a mid-range bottle of wine, price of a loaf of bread (1 lb.), the price of a gallon of milk and price for a 12 oz. cup of black coffee. All prices are in U.S. dollars.

You use this information to run a Multiple Linear Regression to predict Cost of living, along with calculating various descriptive statistics. This is given in the Excel output (that is, the MLR has already been calculated. Your task is to interpret the data).

Based on this information, in which city should you open a second office in? You must justify your answer. If you want to recommend 2 or 3 different cities and rank them based on the data and your findings, this is fine as well.

Based on the MLR output, what variable(s) is/are significant?
From the significant predictors, review the mean, median, min, max, Q1 and Q3 values?
It might be a good idea to compare these values to what the New York value is for that variable. Remember New York is the baseline as that is where headquarters are located.
Based on the descriptive statistics, for the significant predictors, what city has the best potential?
What city or cities fall are below the median?
What city or cities are in the upper 3rd quartile?

    • Compare the descriptive statistics of the other cities to NYC. This will provide context.

3. City Selection Based on Descriptive Statistics:

  • "Best Potential" City:
    • Consider factors that would be attractive to a marketing company:
      • Lower cost of living (to reduce operating expenses).
      • Reasonable cost of housing (for potential employees).
      • Affordable transportation.
      • Consider the cost of things that employees would enjoy, such as wine, and coffee.
    • For each significant variable, identify cities that have values that are favorable compared to NYC.
    • Look for cities that consistently rank well across multiple significant variables.
    • Consider the overall cost of living index.
  • Cities Below the Median:
    • For each significant variable, identify cities with values below the median.
    • These cities represent the lower end of the cost spectrum.
  • Cities in the Upper 3rd Quartile:
    • For each significant variable, identify cities with values in the upper 3rd quartile.
    • These cities represent the higher end of the cost spectrum.

4. Recommendation and Justification:

  • Choose a City (or Cities): Based on your analysis, recommend the city (or cities) where the marketing company should open a second office.
  • Justify Your Choice:
    • Explain how the city's cost of living and other factors align with the company's goals.
    • Use specific data points from your MLR and descriptive statistics to support your claims.
    • Address any potential drawbacks of your chosen city.
    • Rank the cities from best to worst, if multiple cities are chosen.
  • Example Justification Points:
    • "City X has a significantly lower cost of living index than NYC, and its average rent for a 3-bedroom apartment is [amount] lower."
    • "City Y has a very affordable transportation system, with a monthly pass costing only [amount]."
    • "City Z has a very high Q3 for rent, so therefore it is not recommended."

Example Analysis (Hypothetical):

Let's imagine (for illustrative purposes) that your MLR output shows that "3-bedroom apartment" and "monthly transportation pass" are the only significant variables.

  • Descriptive Statistics:
    • You find that City A has a significantly lower average rent and transportation pass cost than NYC.
    • City B has a moderate rent but a very low transportation cost.
    • City C has very high rent.
  • Recommendation:
    • You might recommend City A as the top choice, as it offers significant cost savings in both housing and transportation.
    • City B could be a second choice.
    • City C would not be recommended.

Important Notes:

  • Remember to use the actual data from your Excel output.
  • Consider qualitative factors that might be relevant (e.g., availability of talent, market potential, cultural fit).
  • Clearly explain your reasoning and provide evidence for your claims.
  • Consider the overall cost of living index when making your final decision.

Sample Answer

       

Identifying Significant Variables from the MLR Output:

  • Look for P-values: In your MLR output, the "P-value" column (or "Significance F" for the overall model) indicates the statistical significance of each variable.
    • Variables with P-values less than 0.05 are generally considered statistically significant.
    • List the variables (3-bedroom apartment, transportation pass, wine, bread, milk, coffee) that have significant P-values.

2. Descriptive Statistics Analysis of Significant Predictors:

  • Extract Values: For each significant variable, extract the following from your descriptive statistics:
    • Mean
    • Median
    • Minimum (Min)
    • Maximum (Max)
    • First Quartile (Q1)
    • Third Quartile (Q3)
  • Compare to New York:
    • Find the corresponding values for each significant variable in New York City (the baseline).
