Stat Critique 1 Grading Guide

Pop Visualization (NYT) & Scientific Visualization

1. Visualization included!

2. Aesthetics are correctly identified

Double Encoding

It’s okay if they only mention one of the aesthetics that a variable is associated with when it is mapped to multiple aesthetics.

Growing

  • Doesn’t name variables mapped to each aesthetic (e.g., only says the x-axis, y-axis, and color are used)

Feedback: We want you to state specifically the names of the variables mapped to each aesthetic!

  • Says a color aesthetic is used but the same color is used for every observation

Feedback: Careful! Aesthetics are places where variables are being incorporated into the plot. Is the color in this plot associated with a variable?

  • Misses an aesthetic that is being used

Feedback for general plots: You’ve got a great start, but there are some aesthetics in this plot that are missing from your description. Technically, there are [multiple plots / multiple colors / multiple lines] not just one. What variable is associated with these separate [plots / colors / lines]?

Feedback for maps: You’ve got a great start, but there are some aesthetics in this plot that are missing from your description. Technically, we have “hidden” x- and y-variables. What variables are associated with the location of a state on the map?

3. Offers two aspects the visualization does well

Growing

  • Only says one thing the visualization does well

Feedback: Careful! You were asked to provide TWO aspects of the visualization that are done well.

  • At least one statement about what the visualization does well is unclear

Feedback: I’m having a hard time understanding what specific aspect you believe the visualization does well.

4. Offers two aspects of the visualization that could be improved

Growing

  • Only says one thing the visualization does well

Feedback: Careful! You were asked to provide TWO aspects of the visualization that could be improved.

  • At least one statement about what the visualization does well is unclear

Feedback: I’m having a hard time understanding what specific aspect you believe could be improved.
