    | Would recommend.

    Not too easy. Not too difficult.

    Course Overview:

    I recommend this course because it is a self explanatory course where the material is easy to understand if you attend every class, write notes, and practice through completing the homework.

    Course highlights:

    I learned how to interpret statistical data and conduct statistical research referring to Economics.

    Hours per week:

    6-8 hours

    Advice for students:

    I highly suggest to complete the homework because the only way you are able to fully understand the material is through lots and lots of practice.
