Business scenario

In order to open a new plant to increase the foreign direct investment, the board of directors in Renault Corporation requires a feasibility report to justify the decision. For this, the company aim to predict the demand level on Renault cars in the next few years and to achieve this, they aim to determine the optimal capacity of the new plant. Therefore, in order to make the right decision they consulted Evaluating and Monitoring department to collect relevant business and economic data. The survey considered the following areas: GDP Per Capita Current $ (annual), Population Growth Rate % (annual), Cars’ Sales (annual) (data are available in National Economy Data Excel sheet) from Turkish Economic Data.

Furthermore, in order to get more data, Marketing-Research department prepared a questionnaire in which they asked the individuals the following closed- ended questions:

1.       What is you preferred car?

2.       Your preferred car’s price compared to other brands is: Very expensive? Expensive? Neither expensive nor cheap? Cheap or very cheap?

3.       Your preferred car’s price compared to the brands quality is very high, high, reasonable, low, or very low?

4.       What is your current disposable income?

5.       What is your neighbourhood?

6.       What is your educational qualification? (Data available in Questionnaire data Excel sheet)

The financial and operations managers in one of the existing Renault cars’ accessories stores located in Zeytinburnu that want to predict the money amount that every customer spends per shopping trip. The Monitoring & Evaluating department has adequate historical data to consider standard deviation of population as known at the value of 400 Turkish Lira. The financial manager asked the Monitoring & Evaluating department to collect a random sample of 100 customers’ expenditure spent per shopping trip.



Organizations in all industries increasingly rely on data to make critical business decisions—which new products to develop, new markets to enter, new investments to make, and new (or existing) customers to target. They also use data to identify inefficiencies and other business problems that need to be addressed. In these organizations, the job of the data analysts is to assign a numerical value to these important business functions so performance can be assessed and compared over time. But the job involves more than just looking at numbers: An analyst also needs to know how to use data to enable an organization to make more informed decisions by interpreting data and analysing results using statistical techniques.

As a business and economic data analyst in Renault Corporation, you have been asked to produce a report about business and economic data evaluation where you have to achieve the following:


Assignment Brief

1.       Provide  a  critical  evaluation  of  different  business  data/  information  by applying different data analysis methods considering data types, sources and sufficiency,

a)       the importance of converting data into information,

b)       and the significance of different data analysis methods to investigate the relationships between different dataset variables such as:

c)       the relationship between cars’ sales & GDP growth date,

d)       the relationship between cars’ sales & population growth rate, the relationship between respondent’s income & his/her opinion about the car’s price,

e)       And the relationship between respondent’s education level & his/her preferred car and to help Renault Corporation determine the expected demand level.

2.       Analyze and evaluate Renault cars’ sales data in Mersin and Bursa by:

a)       Applying descriptive data analysis for each of them. And show how you can use the results of analyzing these two data series to determine the city where the sales were more stable.

b)       Evaluating the feasibility of calculating measures of central tendency and measures of variability for the questionnaire and sales data to generate useful information that can help the managers understand the market conditions and make the right decisions.

3.       Evaluate the differences in application between inferential statistics and measuring associations by:

a)       Applying inferential statistics (sampling) to suggest an interval that can contain the mean of customers’ money amount spent per shopping trip in Renault care accessories store during the next two months according to the data available in the random sample (data is available in “Customers` Purchases Sample” sheet of Excel file). The financial manager asks for significance level for mean of 1% and 5%. Compare and interpret the results.

b)       Applying measuring association between each of the two cost items and sales amounts in Mersin branch (you can use Excel to run simple linear regression analysis and show scatter diagram). Depending on P value, determine whether the relationship between commercials costs and sales amounts or between training costs and sales amounts is statistically significant at the significance level of 5%. (data is available in Sales Training & Advertising Data sheet of the Excel file).

4.       Critically evaluate the differences between descriptive, confirmatory, and exploratory analysis by:

a)       Explaining why researchers generally depend on exploratory method when they run qualitative statistical studies?

b)       Suggesting an appropriate Null and Alternative hypotheses to be tested in order to study the relationship between training expenditure and sales amounts and using the results of simple linear regression analysis between these two variables to test these hypotheses.
