Figure 3
The line graph shows “Expected Value” plotted against “Person Location (logits)”. The horizontal axis is labeled “Person Location (logits)” and ranges from negative 14 to 11 with labeled ticks at negative 14, negative 9, negative 4, 1, 6, and 11. The vertical axis is labeled “Expected Value” and ranges from 0.0 to 4.0 with increments of 1.0 unit. A smooth S-shaped curve begins near (negative 14, 0.0), remains close to 0.0 until about (negative 6, 0.1), then rises steeply between (negative 5, 0.5) and (negative 2, 2.0). The curve continues upward to around (1, 2.8), gradually approaches (4, 3.0), and then increases slowly toward the upper boundary, reaching near (11, 4.0) and leveling at 4.0. A dashed horizontal reference line appears at y equals 4.0. Three black data points appear near the middle of the curve around (negative 2.5, 2.0), (0, 2.4), and (2.5, 2.7). Small red tick marks are shown along the horizontal axis near values between negative 2 and 3, marking threshold locations. Note: All numerical data values are approximated.ICC for item 83 in early iterations of the MEL scale. Source: Authors’ own work
