“…Furthermore, for persons with abilities within the range of practical interest here (-4 ≤ θ ≤ 4), there are more than 50% chances for correct performance of at least two attributes. On the other hand, the cutting θ-scores on the logit scale at which a person has more than 50% chances to perform correctly at least 3, 4, 5, 6, or 7 attributes are (a) θ ≈ -0.5 for at least 3, (b) θ ≈ 0.5 for at least 4, (c) θ ≈ 1.0 for at least 5, (d) θ ≈ 1.5 for at least 6, and (e) θ ≈ 2.0 for at least 7 attributes, respectively [65][66][67][68][69].…”
