marginally significantp = .07
In other words, the K estimates increased from Set Size 2 to Set Size 4 and stopped increasing thereafter (as supported by marginally significant linear, F (1, 53) = 3.4, p = .07, η p 2 = 0.06, and significant quadratic, F (1, 51) = 8.9, p < .01, η p 2 = 0.14, effects.
