Measurement Characteristics of the HSCI.
Tolsma, Robert J.; And Others
The report determines the characteristics of the High School Characteristics Index (HSCI) both as a group and person measuring instrument. Four objectives are listed: (1) determine the item characteristics of the index as a group measurement instrument by using the ratio between means variance to within means variance as an index of item discrimination; (2) contrast the above analysis with the inappropriate procedure of item scale correlation and the correlation of the item means for the total group with the mean scale scores as indices of item discrimination; (3) estimate the reliability of the index both as a group and person measuring instrument; and (4) check the hypothesized factor structure using multiple group factor analysis. The index was administered to 3365 junior and senior students in 16 Iowa high schools and tested as to item discrimination, reliability and factor analysis. Findings indicate that the HSCI should not be used as a measurement device to assess similarities or differences between groups of individuals. The index can be used as a measure of individual rather than group difference. [Not available in hard copy due to marginal legibility of original document.] (Author/MC)
