Data Science Achievements#
In this course there are 5 learning outcomes that I expect you to achieve by the end of the semester. To get there, you’ll focus on 15 smaller achievements that will be the basis of your grade. This section will describe how the topics covered, the learning outcomes, and the achievements are covered over time. In the next section, you’ll see how these achievements turn into grades.
Learning Outcomes#
By the end of the semester
(process) Describe the process of data science, define each phase, and identify standard tools
(data) Access and combine data in multiple formats for analysis
(exploratory) Perform exploratory data analyses including descriptive statistics and visualization
(modeling) Select models for data by applying and evaluating mutiple models to a single dataset
(communicate) Communicate solutions to problems with data in common industry formats
We will build your skill in the process and communicate outcomes over the whole semester. The middle three skills will correspond roughly to the content taught for each of the first three portfolio checks.
Schedule#
The course will meet MWF 3-3:50pm in Chafee Social Sci Center 235. Every class will include participatory live coding (instructor types code while explaining, students follow along)) instruction and small exercises for you to progress toward level 1 achievements of the new skills introduced in class that day.
Programming assignments that will be due each week Tuesday by 11:59pm.

Assignments and Skills#
Using the keywords from the table above, this table shows which assignments you will be able to demonstrate which skills and the total number of assignments that assess each skill. This is the number of opportunities you have to earn Level 2 and still preserve 2 chances to earn Level 3 for each skill.

Warning
process achievements are accumulated a little slower. Prior to portfolio check 1, only level 1 can be earned. Portfolio check 1 is the first chance to earn level 2 for process, then level 3 can be earned on portfolio check 2 or later.
Portfolios and Skills#
The objective of your portfolio submissions is to earn Level 3 achievements. The following table shows what Level 3 looks like for each skill and identifies which portfolio submissions you can earn that Level 3 in that skill.
