+Inter-rater and inter-rater reliability
+=======================================
+
+
+## Data set
+
+- 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)
+
+The data can be found [here](goniometer.xlsx).
+
+
+## The Challenge
+
+Visualize the data to answer the following questions:
+
+- Inter-goniometer: do the two goniometers agree?
+- Intra-goniometer: do the goniometers measure consistently the knee joint angle across the three repeated measurements?
+
+
