It also helps evaluating the reliability of the measurement by Cronbach Alpha coefficient
The total M-FAST internal consistency and the internal consistencies of the subscales (although they were not used in practice) were calculated by Cronbach alpha coefficient
To calculate Cronbach's alpha coefficient
, first standard deviation (SD) of scores for each subset of questions of questionnaire and standard deviation (SD) of all questions must be computed then obtain alpha coefficient
of each subset of questions using below formula:
Light Foot and Oliver (1985; quoted from Rajabi, 2005) reported the Cronbach's alpha coefficient
of the Beck Short-Form and retest reliability within two weeks equal to 0.
Fraser, Hadjimichael, and Vollmer (2001) reported an alpha coefficient
Statistical processing of the findings by a means of Software Package for Social Sciences (SPSS) included the following computations: frequencies of responses, Cronbach's Alpha coefficient
, which defines the reliability, and Pearson's correlation coefficients.
He postulated that a fund manager's unique skill in forecasting market turns and selecting undervalued securities for his portfolio can be measured empirically by analyzing a portfolio manager's alpha coefficient
Reliability analysis, such as Guttman test, Spearman Brown, Cronbach alpha coefficient
and item total item correlations were applied to assess the degree of internal consistency and homogeneity between the items.
The authors reported good internal consistency with a Cronbach alpha coefficient
Internal consistency reliability of the scales was assessed by calculating Cronbach's alpha coefficient
The new experiment did not confirm Kandinsky's hypothesis in terms of distribution of results, percentages of maximum marks and Cronbach's alpha coefficient
This 18-item self-report scale was developed with an interdisciplinary sample of health care professionals, and tests for internal consistency produced an average Cronbach's alpha coefficient
