Company Data Analysis - PPT Only

Data analysis project guideline

1. Each group will be assigned a company by the professor. Revenue data and macro data can be find

in Doc sharing on ecollege.

2. Time: the presentation should be no longer than 10 minutes. One group member can record the

voice-over on behalf of the whole group or all members can share the recording.

3. Part I Time Series analysis: discuss the revenue data similar to what I have showed in the Sear

example is expected. First explain what the graph tells you as a manager about the trend,

seasonality, and structural break in this company data. Then conduct research to find out how

management actually made the decisions in the data.

Note: you do not need to provide the graphs that cannot be obtained using Excel (eg. the four

figures shown in the second to last slide in the Time Series Analysis ppt file)

4. Part II Linear regression using Macro data:

a. Select one variable from the macro data file that you believe can be highly correlated with

the revenue data.

b. Run a simple linear regression using the macro variable as the independent variable and the

revenue data as the dependent variable. Report the regression results: show the excel

output.

c. Note that the dates for the revenue data and macro variables do not necessarily match each

other. You will need to determine the date range that has available data for all variables and

drop the extra data. For example, if the date for GDP ranges from 2000 to 2015 and the

revenue data ranges from 1995 to 2016. Then you would only keep data from 2000 to 2015.

For d and e, show and highlight the relevant excel output on the slide during your discussion.

d. Comment on the significance of the slope coefficient. Briefly discuss the relationship

(positive or negative) between the dependent variable and the independent variable. Is the

relationship expected?

e. Report R-squared and briefly comment on the fitness of the model based on your opinion.

5. Again:

a. make sure the font you use is big enough for the audience to read;

b. do not put everything you want to say on the ppt slides;

c. do not read the ppt slides;

d. rehearse before formal presentation;

6. Remember to turn in the ppt file to Dropbox before the deadline. Only one copy is needed from

each group.
