# Midterm I

• Friday 3/1 5pm through Sunday 3/3 11:55pm.
• Self-scheduled exam instructions. In particular:
• Only print from macOS computers.
• At some point you’ll need to wait 5-10 seconds for a “paper is held in queue” pop-up box to appear before you can print.
• Exam length:
• You will be given 140 mins to complete it (including transit time to writing area), however it is timed with the goal that most students will complete it much sooner.
• Timestamps will be strictly enforced. Any timestamps indicating than more than 140 minutes are subject to a 50% penalty and an honor board case.
• All Office of Disability Services forms must be submitted before the midterm start time.
• Other details:
• Closed-book, no internet, and individually completed.
• Bring colored pencils

## Topics

• Topics: Lectures 1-11 & Labs 1-3. In other words everything up to and including regression with one numerical predictor.
• No DataCamp questions. No questions involving extensive coding from memory, but you may still be asked minor coding questions and asked to write pseudocode (see practice midterm).
• What to study:
• Practice midterm questions PDF. This practice midterm is much longer than you can expect on your midterm. Solutions will be distributed on Wednesday.
• Your hand-written course notes first: they are the “executive summaries” of topics.
• The material on the course webpage chronologically, in particular the ModernDive readings.
• Problem sets corresponding to labs.

# Midterm II

• Friday 4/12 5pm through Sunday 4/14 11:55pm.
• Self-scheduled exam instructions. In particular:
• Only print from macOS computers.
• At some point you’ll need to wait 5-10 seconds for a “paper is held in queue” pop-up box to appear before you can print.
• Exam length:
• You will be given 140 mins to complete it (including transit time to writing area), however it is timed with the goal that most students will complete it much sooner.
• Timestamps will be strictly enforced. Any timestamps indicating than more than 140 minutes are subject to a 50% penalty and an honor board case.
• All Office of Disability Services forms must be submitted before the midterm start time.
• Other details:
• Closed-book, no internet, and individually completed.
• Bring colored pencils.

## Topics

• Topics:
• Lectures 9-24. In other words everything up to and including the resampling activity, but not confidence intervals.
• ModernDive Chapters 6, 7, 8, and 9 up to and including 9.2.
• No questions involving extensive coding from memory, but you may still be asked minor coding questions and asked to write pseudocode (see practice midterm).
• No direct DataCamp questions, but note that it covers the same material as we covered in class so it is good practice.
• What to study:
• Practice midterm questions PDF.
• This practice midterm is longer than you can expect on your midterm.
• The question on “1. Seattle House Prices” is much harder than you can expect.
• You can skip “4. Sampling Distribution” part a)/
• Your hand-written course notes first: they are the “executive summaries” of topics.
• The material on the course webpage chronologically, in particular the ModernDive readings.
• Problem sets corresponding to labs.

# Midterm III

• Between Tuesday May 7th and Friday May 10th: See email titled “Self-Scheduled Final Exams May 7-10” sent on April 15th.
• Other details:
• Closed-book, no internet, and individually completed.
• Bring colored pencils.
• Bring a calculator. Scientific calculators are acceptible, but smartphone calculators are not.
• Office hours: Monday 5/6 from 1pm-5pm and Wednesday 5/8 from 10am-12pm and 1pm-3pm by appointment. If a particular slot is booked, please feel free to still come!
• I will also be on Slack during reading week; please post questions in #questions channel.

## Topics

• Lectures 20-40.
• ModernDive Chapters 8, 9, 10, and 11.
• No DataCamp.
• No coding questions.

Top priorities to study:

1. Midterm II solutions covered in Lecture 36: One question from Midterm III will be asked again
2. Practice Midterm III and corresponding solutions, in particular the “Formatting is off” question we covered in class in Lectures 39 and 40. This will give you the best sense of what types of questions you’ll be asked: no coding questions, but rather conceptual and more pen/paper type questions. If there is anything you don’t understand, refer back to class notes and the corresponding lab.
3. ModernDive Section 8.5.2 Table 8.6 on the different sampling scenarios: Be able to generalize sampling and inference to all 6 scenarios.
