Figure 2: Comparison of the 95%-confidence intervals for test-retest reliability for test lists with 20 words (top) and with 40 words (bottom) when applying the five calculation methods. To improve comparability, the right side shows an enlargement of the central sector of the left figures, respectively. Black: method 1, dark blue: method 2, magenta dashed: method 3, red dashed: method 4, light blue: method 5.
