In Week 8, we’ll be reviewing Midterm Exam I, and then move to the next new topic, data management.

Midterm Exam I (Fall 2025)

To get a sense of the exam style and format, you can review last year’s version below:

Calculation for Total Exam Score

\[ \begin{align} &\quad(\text{Midterm Exam Score})\\ &= \max\left\{0.50 \times \text{(Midterm 1 Score)} + 0.50 \times \text{(Midterm 2 Score)},\right.\\ &\qquad\quad\;\;\,\left.0.33 \times \text{(Midterm 1 Score)} + 0.67 \times \text{(Midterm 2 Score)}\right\}. \end{align} \]

  • The Midterm Exam Score will be the higher of the following two calculations:

    1. The simple average of Midterm Exam 1 and Midterm Exam 2
    2. The weighted average, with one-third weight on Midterm Exam 1 and two-thirds weight on Midterm Exam 2

\[ \begin{align} &\quad(\text{Total Exam Score})\\ &= \max\left\{0.50 \times \text{(Midterm Exam Score)} + 0.50 \times \text{(Final Exam Score)},\right.\\ &\qquad\quad\;\;\,\left.0.25 \times \text{(Midterm Exam Score)} + 0.75 \times \text{(Final Exam Score)}\right\}. \end{align} \]

  • The Total Exam Score will be the higher of the following two calculations:

    1. The simple average of Midterm Exam and Final Exam
    2. The weighted average, with one-fourth weight on Midterm Exam and three-forth weight on Final Exam.

How Midterm Exam 1 Contributes to Your Total Exam Score

Scenario 1

  • Suppose your \((\text{Total Exam Score})\) is taken from: \[ \begin{align} &0.33\times(\text{Midterm Exam 1}) \,+\, 0.67\times(\text{Midterm Exam 2})\\ &0.25\times(\text{Midterm Exam}) \,+\, 0.75\times(\text{Final Exam}) \end{align} \]
  • \((\text{Midterm Exam 1})\) will then account for 8.25% of your \((\text{Total Exam Score})\).

Scenario 2

  • Suppose your \((\text{Total Exam Score})\) is taken from: \[ \begin{align} &0.5\times(\text{Midterm Exam 1}) \,+\, 0.5\times(\text{Midterm Exam 2})\\ &0.25\times(\text{Midterm Exam}) \,+\, 0.75\times(\text{Final Exam}) \end{align} \]
  • \((\text{Midterm Exam 1})\) will then account for 12.5% of your \((\text{Total Exam Score})\).

Scenario 3

  • Suppose your \((\text{Total Exam Score})\) is taken from: \[ \begin{align} &0.33\times(\text{Midterm Exam 1}) \,+\, 0.67\times(\text{Midterm Exam 2})\\ &0.5\times(\text{Midterm Exam}) \,+\, 0.5\times(\text{Final Exam}) \end{align} \]
  • \((\text{Midterm Exam 1})\) will then account for 16.25% of your \((\text{Total Exam Score})\).

Scenario 4

  • Suppose your \((\text{Total Exam Score})\) is taken from: \[ \begin{align} &0.5\times(\text{Midterm Exam 1}) \,+\, 0.5\times(\text{Midterm Exam 2})\\ &0.5\times(\text{Midterm Exam}) \,+\, 0.5\times(\text{Final Exam}) \end{align} \]
  • \((\text{Midterm Exam 1})\) will then account for 25% of your \((\text{Total Exam Score})\).
