**Previous Exams**

- Midterm Exam 1.: On Descriptive Statistics
- Fall 2015, Spring 2016, Fall 2016, Spring 2017, Fall 2017, Spring 2018, Fall 2018, Spring 2019, Fall 2019, and Spring 2020
- As for Fall 2020, I have posted here the print-out of the Canvas exam for Section II and Section III along with the formula sheet. The answer to each question appears as the first choice. Those choices were reshuffled, however, for each student and over each attempt. Later on, my GTAs will put these exams into their formal format.

- Midterm Exam 2.: On Probability
- Fall 2015, Spring 2016, Fall 2016, Spring 2017, Fall 2017, Spring 2018, Fall 2018, Spring 2019, Fall 2019, and Spring 2020
- As for Fall 2020, I have posted here the print-out of the Canvas exam for Section II and Section III along with the formula sheet. The answer to each question appears as the first choice.

- The Final: On Inferential Statistics
- Comprehensive Make-up Exam: On Descriptive Statistics and Probability

**Statistical Packages and Econometrics**

As described in Course Description, I use MS Excel to illustrate how descriptive and inferential statistical analyses may be conducted using computers. This software is chosen because students have already had some exposures to MS Office, and they also have free access to this package at the University of Oklahoma.

Upon completion of this course, students are able to learn more about statistical packages. As indicated in the lecture series, there are many packages out there. (Wikipedia, for instance, keeps a long list of those packages). Given what students have access to at the University of Oklahoma, I recommend the following courses.

Go on Lynda, sign in using your 4×4, and look for:

- Statistics with Excel (part one is 3h45m, and part two is 2h)
- Learning R (2h25m)
- R for Excel Users (1h26m)
- R Statistics Essential Training (5h59m)
- Python for Data Science Essential Training (6h32m)

The above are video series, using which you may learn how to employ statistical packages for descriptive and inferential statistical analyses. At this point, this is your choice. Given your background and interest, you may choose any of the above courses. Excel is already available to you. R and Python are also freely available. Go for the package of your choice, and have fun learning.

Also, if you would like to learn more about applied statistics and inference in economics, I encourage you to take this online course in econometrics. It is offered by Dr. Josh Angrist, who is an MIT econometrician. If you would like to go into more details, I encourage you to take the econometrics course that is offered regularly at our department. The above online course could, in fact, complement our on-campus course.
