Introduction

In this 5-minute presentation you will describe a real-world example of biased data. Sticking with our focus from last week, you should prioritize working on the structure, clarity, and conciseness of your presentation.

Different from last week, you are not expected to make an argument in this presentation. The information you share can be purely expository. In this regard, your goal is develop among your peers a clear understanding and appreciation of your example.

Evaluation

Your presentation will be scored in the following dimensions:

  1. Structure and format - 3 pts
    • A score of 3/3 clearly fulfills items #1-3 under “Expectations” and is exceptionally organized and structured.
    • A score of 2/3 fails to fulfill at most one of #1-3 under “Expectations” or contains clear structural flaws.
    • A score of 0/3 fails to fulfill two or more of #1-3 under “Expectations”.
  2. Content - 4 pts
    • This score is a holistic assessment of how well your presentation conveys the things listed in item #4 under “Expectations”.
  3. Delivery - 3 pts
    • A score of 3/3 reflects a delivery with a pacing, speaking volume, and rhythm that are engaging but not overwhelming. This is something you should practice! If you tend to be soft-spoken, you should practice speaking more audibly with greater emotion. If you tend to be an overly energetic speaker, you should practice a calmer and more authoritative delivery.
    • A score of 2/3 reflects a delivery with 1-2 areas that could be improved upon to increase engagement. (ie: stumbling over transitions, needing to backtrack, minor issues with pacing or speaking volume, etc.)
    • Scores of 0/3 or 1/3 reflect major issues related to delivery that overwhelm the content of the presentation (ie: speaking too quietly to be heard, or speaking so fast that no one can keep up, etc.)

You will also be responsible for a \(\leq1\)-page written reflection that discusses what you’ve learned from the presentation describes 1-2 skills that you’d like to improve upon in future presentations. This reflection will be scored holistically with a maximum score of 5 pts.
