Abstract
This article describes the construction of a scale for the measurement of attitude toward Chicanos using the method of equal-appearing intervals as outlined by Thurstone and Chave. The description includes the methods and procedures used for the collection of statements. The procedures used to calculate the median, that is, the scale value (S value) and the interquartile range (Q value) for each of the items are delineated. Both the S values and the Q values constitute the criteria for the final selection of the items for two forms of the scale. The results are set forth together with the methods for scoring the scale. Finally, the result of equivalent-forms method used to estimate the reliability of the scale is reported.
