Get involved and develop your data visualisation knowledge & skills.

Here's how it works:

• Each month a new challenge will be provided, including access to the relevant dataset.
• Download the data, and develop your own data visualisations.
• Develop your graphics and code (using any programming language or tool) and submit your entry.
• Attend the monthly webinar, to hear your submission discussed by our expert panel. Alternatively, please feel free to simply attend the webinars, view the submitted graphics and listen to the panel discussion.

We welcome suggestions for new challenges! Please feel free to submit your idea here or send us an e-mail.

Current Challenge: inter-rater and intra-rater reliability

Data:

• The data is based on a paper by Eliasziw et al., 1994.
• One therapist uses two goniometers (i.e., electro vs. manual) to measure knee joint angles three times.
• Twenty-nine subjects (n=29) were measured three consecutive times (m=3) on each goniometer (t=2) at one joint position (i.e., full passive extension)

Challenge:

• Inter-goniometer: do the two goniometers agree?
• Intra-goniometer: do the goniometers measure consistently the knee joint angle across the three repeated measurements?
