What is Thurstone's method of pair comparisons?
Thurstone's method of pair comparisons can be considered a prototype of a normal distribution -based method for scaling-dominance matrices. Even though the theory behind this method is quite complex (Thurstone, 1927a), the algorithm itself is straightforward.
What is the difference between Rasch and Thurstone's law?
The Rasch model has a close conceptual relationship to Thurstone's law of comparative judgment (Andrich, 1978), the principal difference being that it directly incorporates a person parameter. Also, the Rasch model takes the form of a logistic function rather than a cumulative normal function.
What is the most frequent recourse when the 1.00-0.00 frequencies are encountered?
The most frequent recourse when the 1.00-0.00 frequencies are encountered is their omission. Thus, e.g., Guilford (1954, p. 163) has recommended not using proportions more extreme than .977 or .023, and Edwards (1957, pp. 41–42) has suggested that “if the number of judges is large, say 200 or more, then we might use pij values of .99 and .01, but with less than 200 judges, it is probably better to disregard all comparative judgments for which pij is greater than .98 or less than .02."’ Since the omission of such extreme values leaves empty cells in the Z matrix, the averaging procedure for arriving at the scale values cannot be applied, and an elaborate procedure for the estimation of unknown parameters is usually employed (Edwards, 1957, pp. 42–46). An alternative solution of this problem was suggested by Krus and Kennedy (1977).
Who said attitudes can be measured?

How do you Apply the Thurstone Scale?
You would typically apply the Thurstone scale in scenarios where you want to quantify the attitudes of people on specific issues and compare these between different respondents. The Thurstone scale is especially useful for measuring how strong an opinion a respondent holds on a certain issue. It can also be used to determine general group feelings on a subject such as in customer satisfaction measures for shops.

How is Thurstone Scaling similar to Equal-Appearing Intervals?
All of them begin by focusing on a concept that is assumed to be unidimensional and involve generating a large set of potential scale items. All of them result in a scale consisting of relatively few items which the respondent rates on Agree/Disagree basis. The major differences are in how the data from the judges is collected. For instance, the method of paired comparisons requires each judge to make a judgement about each pair of statements. With lots of statements, this can become very time consuming indeed. With 57 statements in the original set, there are 1,596 unique pairs of statements that would have to be compared! Clearly, the paired comparison method would be too time consuming when there are lots of statements initially.

This is where attitude scales come into the picture. Scales are used to associate a numerical value with respondent behavior and thoughts. It is possible to have a number corresponding to attitudes only when the attitude is considered accountable on only one scale (uni-dimensional scale).
