Experiment AE
This interactive scatterplot explores eye-tracking data from a WPI MAPLE Lab study, showing how problem order relates to metrics like average fixation duration, response time, or no-fixation percentage. Users select the y-axis variable via a menu, and each point is colored by correctness. The visualization uses d3.scaleLinear for axes, d3.scaleOrdinal for color mapping, and displays a red trend line computed via linear regression. Hovering over the d3 color legend highlights correct or incorrect data points. Data is loaded from a CSV and parsed with d3.csvParse.
AI-generated descriptionThis is a dataset from WPI MAPLE Lab study conducted in 2021-2022. 86 undergraduate students solved math problems in the lab and their eye-movements during the solving process were collected with eye-tracking software. Each participant solved 24 problems: 12 with and 12 without brackets.
Data dictionary:
- Participant_ID' - Anonymized participant ID. Categorical.
- 'Problem_ID' - Problem title. Categorical.
- 'Order' - The order of the problem in the experiment. Ordinal.
- 'Brackets' - If equation contains brackets. Categorical.
- 'Response_time' - How long did it take fot participant to response. Quantitative.
- 'Correct_or_not' - If participant’s response was correct ot not. Categorical.
- 'Average_duration_of_fixations' - How long participant fixated on each digit (on average). Quantitative.
- 'No_fixation_percentage' - On how many digits participant did not fixate? Quantitative.
The following information could be visualized:
- Did average fixation duration change over the time of the experiment? Did it change differently in different participants?
- Was response time associated with correctness? Did this association change over the time of the experiment?
- Did people tent to answer longer in problems with brackets and did this association change over the time of the experiment?
- Was tendency to use peripheral vision associated with response corectness? Did this association change over the time of the experiment?
