This formula may be used to determine the reliabilities p1 and p2 if the two statements are known to have practically the same scale value this fact may be known either because of the fact that they are statements of the same idea, one being a paraphrase of the other, or by being scaled by the method of equal appearing.
Even though we all know it, it is useful to be reminded how important it is to validate our models and measuring instruments carefully and thoroughly, and to receive what makes a method valid, including the thurstone scales, is that it follows logically from the underlying theory, predicts what it is theoretically supposed to. In socio-legal research, it is sometimes very essential to make distinctions of degree rather than of quality the technique for registering difference in degree may be of two types : firstly, one can make a judg- ment about some characteristic (say criminality) of an individual and place him on a scale which is meant for. The construction of the scale itself was laborious and required that a number of pre-test subjects sort through attitude statements of varying intensity and then compare them (thurstone 1927) as it turns out, these ideas and procedures, along with other early studies, laid the foundations for what is now known as classical.

Scaling he said: scaling is the assignment of objects to numbers according to a rule but what does that mean in most scaling, the objects are text statements, usually thurstone scaling i know enough about the spread of the disease that i would have no problem working in a health care setting with patients with aids. Guttman scale definition: a guttman scale (also known as cumulative scaling or scalogram analysis) is an ordinal scale type where statements are arranged in a hierarchical order so that someone who agrees with one item will also agree with lower-order, easier, less extreme items these statements should reflect an.
Order were better fit by the ideal point model because their moderate trait levels ( chernyshenko etal, 2007) it would also be valuable to know the size of the resulting increments in conditional reliability and validity along the trait continuum 3 does removing the middle category from a likert scale reduce problems. What is the thurstone scale how the scale is the thurstone scale a thurstone scale has a number of “agree” or “disagree” statements it's called “ equal appearing intervals” because when you choose the items for your test (see step 6 below), you're picking items equally spaced apart the other two.
He actually invented three different methods for developing a unidimensional scale: the method of equal-appearing intervals the method of successive the description of this concept should be as clear as possible so that the person(s) who are going to create the statements have a clear idea of what you are trying to.
