The route
Module 1: Encoding
Which perceptual comparison each encoding requires and how accurately it is performed, how scale and baseline choices affect the comparison a reader makes, and what an encoding omits.
- The learner can choose the graphical encoding a stated question requires, justify the choice by what the eye judges accurately, set the scale and baseline so that the visual comparison matches the numerical one, and state which readings the chosen display supports and which it forecloses.
What finishing means
Finishing this course means you have demonstrated the required skills with the level of support this course currently assesses.
1 required skill. If you reach a lesson without the background it assumes, you are pointed at the prerequisite first, and returned here afterwards.
How progress is measured
Progress is inferred from evidence you produce, not from pages you have opened. Each required skill moves through states as evidence accumulates: met, practicing with help, performed unassisted, then performed again after a delay.
This course counts a skill as finished atguided. Where the system cannot admit evidence for a stronger claim — for instance when the only available scoring is your own judgment of your written answer — the skill stays at the state the evidence supports, and the reason is shown rather than hidden.
