Sentence examples for items coefficient from inspiring English sources

Among these methods, scoring by experts selected 36 items, coefficient of variation selected 46 items, discriminatory analysis selected 46 items, multiple regression selected 32 items, Cronbach'α coefficient selected 59 items, coefficient of correlation selected 53 items, factor analysis selected 54 items, and cluster analysis selected 46 items (see additional file 3).

To assess whether an item is coherent enough to be included in the scale, the corresponding item coefficient H i is used.

The reliability of the NEECHAM confusion scale was determined by means of the following reliability indicators: interrater reliability (Cohen's Kappa) and internal consistency (Pearson's item-total coefficient of correlation, Pearson's inter-item coefficient of correlation and Cronbach's alpha).

The internal consistency of the scale is good, as it is in all the other studies [ 16- 19] (Cronbach's alpha ≥ 0.81), and the physiological functions did not correlate with the total item coefficient of correlation.

It was found that while the reading item coefficients appeared to be normally distributed, some of those for the structure items indicated non-normal distribution.

A supplementary partial log likelihood analysis as proposed by Lancsar et al. [24] yielded a similar hierarchy as the interpretation based on the item coefficients.

This process is similar to using inter-item coefficients when testing the Cronbach's α of Likert-type subscales; removal of the original item #2 allowed for the resulting Guttman item pool to reach acceptable reliability.

The inter-item coefficients for the subscales were.51,.44, and.53 respectively, indicating good discriminatory power [ 12].

Only one item, i.e. 'financial impact', had negative inter-item coefficients with six other items in the child impacts section.

The sufficiency of homogeneity is tested by several item coefficients, scale reliabilities Cronbach's α, and phenotypical factorial structure in explorative factor analyses (EFA).

A supplementary (partial) log-likelihood analysis as proposed by Lancsar et al. [ 15] yielded to the same hierarchy as the interpretation based on the six item-coefficients.
